Full textAbstract:
Soccer players perform a variety of training drills to develop the physical, technical and tactical qualities required for match-play. The role of coaches in prescribing training suggests that players may not always meet physical targets set by conditioning staff. To quantify the physical outputs elicited by different training drill types, 183 professional soccer players were monitored over 8 seasons using Microelectromechanical Systems during normal training, yielding 65,825 drill observations [362 ± 341 observations·player−1]. Linear mixed models assessed the influence of drill type, head coach and playing position on physical output. Drills lasted ~14 min, eliciting total distances and high speed running of ~1000 m and 40 m, respectively. Conditioning drills elicited substantially greater relative high-speed running [18.8 ± 27.2 m.min−1] and Sprint [3.5 ± 9.4 m.min−1] distances than all other drill types. The proportion of training drill types used and external outputs elicited per drill were affected by the head coach. Midfielders recorded the highest total distance [77.3 ± 36.1 m.min] and PlayerLoad™ [8.29 ± 3.54] of any playing position, whilst the lowest outputs were recorded by goalkeepers. This study provides reference data for practitioners when seeking to manipulate training prescription to achieve physical output targets whilst also meeting the team’s technical and tactical objectives.

Purpose:To quantify the physiological responses, time–motion characteristics, and reproducibility of various speed-endurance-production (SEP) and speed-endurance-maintenance (SEM) drills.Methods:Sixteen elite male youth soccer players completed 4 drills: SEP 1 v 1 small-sided game (SSG), SEP running drill, SEM 2 v 2 SSG, and SEM running drill. Heart-rate response, blood lactate concentration, subjective rating of perceived exertion (RPE), and time–motion characteristics were recorded for each drill.Results:The SEP and SEM running drills elicited greater (P < .05) heart-rate responses, blood lactate concentrations, and RPE than the respective SSGs (ES 1.1–1.4 and 1.0–3.2). Players covered less (P < .01) total distance and high-intensity distance in the SEP and SEM SSGs than in the respective running drills (ES 6.0–22.1 and 3.0–18.4). Greater distances (P < .01) were covered in high to maximum acceleration/deceleration bands during the SEP and SEM SSGs than the respective running drills (ES 2.6–4.6 and 2.3–4.8). The SEP SSG and generic running protocols produced greater (P < .05) blood lactate concentrations than the respective SEM protocols (ES 1.2–1.7). Small to moderate test–retest variability was observed for heart-rate response (CV 0.9–1.9%), RPE (CV 2.9–5.7%), and blood lactate concentration (CV 9.9–14.4%); moderate to large test–retest variability was observed for high-intensity-running parameters (CV > 11.3%) and the majority of accelerations/deceleration distances (CV > 9.8%) for each drill.Conclusions:The data demonstrate the potential to tax the anaerobic energy system to different extents using speed-endurance SSGs and that SSGs elicit greater acceleration/deceleration load than generic running drills.

Full textAbstract:
Purpose:To examine the acute effects of generic drills (running drills [RDs]) and specific (small-sided-games [SSGs]) long-sprint-ability (LSA) drills on internal and external load of male soccer players. Methods:Fourteen academy-level soccer players (mean ± SD age 17.6 ± 0.61 y, height 1.81 ± 0.63 m, body mass 69.53 ± 4.65 kg) performed four 30-s LSA bouts for maintenance (work:rest 1:2) and production (1:5) with RDs and SSGs. Players’ external load was tracked with GPS technology (20-Hz), and heart rate (HR), blood lactate concentration (BLc), and rating of perceived exertion (RPE) were used to characterize players’ internal load. Individual peak BLc was assessed with a 30-s all-out test on a nonmotorized treadmill (NMT). Results:Compared with SSGs, the RDs had a greater effect on external load and BLc (large and small, respectively). During SSGs players covered more distance with high-intensity decelerations (moderate to small). Muscular RPE was higher (small to large) in RDs than in SSGs. The production mode exerted a moderate effect on BLc while the maintenance condition elicited higher cardiovascular effects (small to large). Conclusion:The results of this study showed the superiority of generic over specific drills in inducing LSA-related physiological responses. In this regard production RDs showed the higher postexercise BLc. Individual peak blood lactate responses were found after the NMT 30-s all-out test, suggesting this drill as a valid option to RDs. The practical physiological diversity among the generic and specific LSA drills here considered enable fitness trainers to modulate prescription of RD and SSG drills for LSA according to training schedule.

Purpose:To quantify the external training loads of positional groups in preseason training drills.Methods:Thirty-three elite rugby league players were categorized into 1 of 4 positional groups: outside backs (n = 9), adjustables (n = 9), wide-running forwards (n = 9), and hit-up forwards (n = 6). Data for 8 preseason weeks were collected using microtechnology devices. Training drills were classified based on drill focus: speed and agility, conditioning, and generic and positional skills.Results:Total, high-speed, and very-high-speed distance decreased across the preseason in speed and agility (moderate, small, and small, respectively), conditioning (large, large, and small) and generic skills (large, large, and large). The duration of speed and generic skills also decreased (77% and 48%, respectively). This was matched by a concomitant increase in total distance (small), high-speed running (small), very-high-speed running (moderate), and 2-dimensional (2D) BodyLoad (small) demands in positional skills. In positional skills, hit-up forwards (1240 ± 386 m) completed less very-high-speed running than outside backs (2570 ± 1331 m) and adjustables (2121 ± 1163 m). Hit-up forwards (674 ± 253 AU) experienced greater 2D BodyLoad demands than outside backs (432 ± 230 AU, P = .034). In positional drills, hit-up forwards experienced greater relative 2D BodyLoad demands than outside backs (P = .015). Conversely, outside backs experienced greater relative high- (P = .007) and very-high-speed-running (P < .001) demands than hit-up forwards.Conclusion:Significant differences were observed in training loads between positional groups during positional skills but not in speed and agility, conditioning, and generic skills. This work also highlights the importance of different external-load parameters to adequately quantify workload across different positional groups.

Purpose: To determine the relationship between drill type and accelerometer-derived loads during various team-sport activities and examine the influence of unit fitting on these loads. Methods: Sixteen rugby league players were fitted with microtechnology devices in either manufacturer vests or playing jerseys before completing standardized running, agility, and tackling drills. Two-dimensional (2D) and 3-dimensional (3D) accelerometer loads (BodyLoad™) per kilometer were compared across drills and fittings (ie, vest and jersey). Results: When fitted in a vest, 2D BodyLoad was higher during tackling (21.5 [14.8] AU/km) than during running (9.5 [2.5] AU/km) and agility (10.3 [2.7] AU/km). Jersey fitting resulted in more than 2-fold higher BodyLoad during running (2D = 9.5 [2.7] vs 29.3 [14.8] AU/km, 3D = 48.5 [14.8] vs 111.5 [45.4] AU/km) and agility (2D = 10.3 [2.7] vs 21.0 [8.1] AU/km, 3D = 40.4 [13.6] vs 77.7 [26.8] AU/km) compared with a vest fitting. Jersey fitting also produced higher BodyLoad during tackling drills (2D = 21.5 [14.8] vs 27.8 [18.6] AU/km, 3D = 42.0 [21.4] vs 63.2 [33.1] AU/km). Conclusions: This study provides evidence supporting the construct validity of 2D BodyLoad for assessing collision/tackling load in rugby league training drills. Conversely, the large values obtained from 3D BodyLoad (which includes the vertical load vector) appear to mask small increases in load during tackling drills, rendering 3D BodyLoad insensitive to changes in contact load. Unit fitting has a large influence on accumulated accelerometer loads during all drills, which is likely related to greater incidental unit movement when units are fitted in jerseys. Therefore, it is recommended that athletes wear microtechnology units in manufacturer-provided vests to provide valid and reliable information.

Objective: Most of the baseball coach whether in amateur or professional level in Taiwan all prefer crossover step for the stolen base and MLB team now encourage player to use drop step for stolen base, therefore this study is to investigate the relationship between the sprinting speed and the initial speed in two different base stealing techniques (Drop step, DS and Crossover step, CS). The research method is as follows: 12 Group A baseball players (age: 25.92±3.5 years, height: 176.86±4.02 cm, weight: 78.25±11.11 kg) who perform two type of base stealing techniques, and the performance are captured by the system of optical gate division timer and three-dimensional motion analysis. The best record is used as analysis data. Statistical analysis: The data obtained in this study was analyzed using for Paired samples t-test Chinese version software. According to statistics, the results show that there is no difference in the number of seconds elapsed between the DS and CS runs, and there is a significant **p < .01 difference in the number of seconds consumed between the start point and the 0-5 meter interval, The number of elapsed seconds for a 10-meter range of metric intervals is significant **p < .01. which means DS is faster than CS on starting point and first few meters interval. Conclusions: There is no difference in the speed of performance of base stealing in DS and CS, but it is more efficient in starting point and initial speed.

The A and B drills are commonly used by sprinters as part of training. The purpose of this study was to compare the biomechanics of the A and B drills to sprinting. Eight university level sprinters were recruited to participate in the study. The participants completed the A and B drills as fast and as technically perfectly as possible, followed by two 60 metre runs at maximum speed. While performing the drills and sprinting, the participants were videotaped from the frontal and sagittal views. These videotapes were then used for a kinematic comparison of the drills and sprinting, based on select variables associated with sprint performance. There were significant differences in vertical displacement, vertical velocity, step frequency, support time, non-support time, shoulder range of motion (ROM), elbow flexion angular velocity (AV), trunk flexion, trunk rotation, pelvic rotation, hip flexion, hip extension AV, knee extension AV, ankle ROM, plantarflexion AV, and dorsiflexion AV. There were no significant differences in shoulder extension AV, elbow ROM, elbow extension AV, hip flexion AV, knee ROM, and knee flexion AV. Differences among the three skills were seen in the timing of peak angular velocity at the shoulder, hip, and knee. Differences among the three skills were also seen in the angle at which peak angular velocity occurred in the shoulder and ankle joint range of motion. It was concluded that the kinematics in the A and B drills were not the same as sprinting. (Abstract shortened by UMI.)

Full textAbstract:
For many runners, running technique is an afterthought—one they don't think about until an injury or plateau keeps them from achieving their goals. Running Form underscores the importance of proper form and shows you how to elevate your performance to the greatest possible extent with the smallest risk of injury. Owen Anderson, PhD, is a coach to elite runners from around the globe. In Running Form, he describes the common problem of runners moving on “square wheels” by braking with each step, adopting inefficient stances, or risking injury with excessive ground impact. He pinpoints the components of good form—foot-strike, shin and shank angle, stance time, cadence, body lean, and posture—to help you understand where you can make small changes that offer significant improvements. Then, using a basic video camera or smartphone, you can analyze your own form and apply specific drills and exercises to correct any deficiencies. Numerous photos incorporate lines and arrows to help you clearly identify the appropriate angles and movements of sound technique. No expensive software or biomechanics degree is required to learn how to run faster and with more efficiency and to significantly reduce your risk of injury. Get rid of those running patterns that hurt performance and destroy running economy. Running Form gives you the knowledge to perfect your running form so you can train consistently and improve with each stride. AUDIENCE A guide for serious runners, coaches, and triathletes. Runners who have experienced chronic injuries due to form flaws will appreciate this book.

This chapter contains instructions for ski detachments in platoons and companies. It first provides the parade formations for a platoon, with directions for forming up, turning, and movement. The chapter then turns to company formations. In all forming up of the platoon and company, the intervals and distances between individuals are the same as those indicated for the platoon parade line. Finally, the chapter turns to company battle-arrays. It provides instructions for when the ski detachments are caught under live fire during actual battle, in which case particular importance accrues to prolonged, rapid running. Furthermore, on the firing line, a rifleman can either be on skis or have skis removed and then drag them behind, according to his preference.

Tommy Tune’s earliest work as a director-choreographer engaged with issues of gender, sexuality, culture, and politics. The Club was an evening of songs and jokes set in an exclusive Victorian-era men’s club that featured all roles played by women. Tune led the cast in creating a stylized body language that approximated male behavior but, as performed by women, blurred gender lines in ways both challenging and exhilarating. The cross-gender performance of this material laid bare its misogyny without overstatement, and The Club was a long-running off-Broadway hit. Tune next joined the creative team of The Best Little Whorehouse in Texas, based on a true story about the closing of a bordello prompted by a crusading television personality. As choreographer and co-director, with Peter Masterson, Tune injected a burst of musical comedy brightness into the homey musical. His creativity was boundless, and numbers featuring macho, clog-dancing football players and a female drill team made up of both live dancers and life-size sex dolls were crowd pleasers that also contributed to the show’s sly skewing of culture and politics.

After much debate, Davis assignd General Joseph E. Johnston permanent command of the Army of Tennessee. Johnston inherited an army that was not prepared to go on the offensive. Davis promoted John Bell Hood, who received a broken arm at Gettysburg and had a leg amputated after Chickamauga, to lieutenant general. After the reassignments, Davis and Bragg pushed for an offensive campaign in middle Tennessee, but Johnston contested due to lack of supplies and troops. Johnston proposed Davis send him troops before an offensive, but to no avail. Johnston improved the discipline of the army by doing things such as running drills for three hours a day and having roll call five times a day. Johnston’s drills and use of mock battles in addition to voluntary re-enlistment of three year-troops lead to increased national identity among Army of Tennessee troops.

Full textAbstract:
In planning for a deepwater well, running/retrieval of a drilling riser in advance of rapidly developing seas was identified as a critical operation. The harsh seastates required careful attention to the well-specific operating criteria, (WSOC), or the metocean conditions that limit specific operations. Certain conditions would warrant the operation being shut down so that the riser could be pulled or run before conditions became excessive. In deep water, a running/retrieval operation can take several days and the consequences of being shut down part way can be severe. Moderately high current profiles can cause the riser to bind in the diverter housing, preventing further running or retrieval. If binding occurs, a dynamically-positioned vessel can carry out “drift running” operations to increase its operability. However, if conditions prohibit further running/retrieval, the riser may need to be hung off “hard” (with no compensation) at the drill floor or “soft” on the tensioners and/or drill string compensator. In such a case, in addition to large top riser angles, vessel heave motion can cause tension variation, depending on the hang-off conditions and the length of the deployed riser. This paper discusses how riser analysis was used to support the operational understanding of the riser running/retrieval process for this deepwater well. The results were used to assist in the planning and decision-making involved in drilling this well.

Abstract Our rig crews regularly work around structures that pose risks such as dropped objects and pinch points. HSE and operational performance is highly dependent on human performance. Human performance or human factors have resulted in a relatively high frequency of serious Health, Safety and Environment (HSE) incidents associated with tubular handling on ADNOC Onshore rigs. An example is the fatality on a rig in Abu Dhabi while preparing to run casing in February 2018. We believe we can prevent major incidents, enhance efficiency and reduce risk by removing our people from harm's way through mechanization and intelligent automation of drill floor activities. The objective of this work is to reduce the human factor as low as reasonably practicable through mechanization and intelligent automation of tubular handling operations on ADNOC Onshore rigs. An incident prevention workshop recommended a technology search to enable hands free operations and reduce the human to machine interaction as much as reasonably practicable. A quick market research and a "Go, See, Assess" exercise with ADNOC Shareholders revealed several potential offerings on the market. ADNOC Onshore collaborated with two major technology providers and jointly designed a mechanized set up for ADNOC Onshore land rigs. The solution involved the use of mechanized equipment such as Casing Running Tools complete with hydraulically actuated single joint elevators, hydraulic catwalk, automated power slips, remote operated tong system with supporting alignment systems, air operated elevators, remote operated stabber, etc. The solution was successfully implemented on multiple rigs. The mechanized set up reduced the number of people in the so called RED Zone by 50% (Stabber, Tong Operator, Thread Inspector and Floor man) during casing and completion running operations. Other benefits realized include: Reduced reliance on human performance Reduced risk of harm to people due to dropped objects and pinch points on the rig floor Assured consistency in executing repetitive tasks such as running casing, etc This level of mechanization and intelligent automation is a first in the ADNOC Group, represents a STEP CHANGE in operational safety and has transformed how we do our business, underpinning HSE as priority number one.

Abstract This paper presents an innovative concept to run Electrical Submersible Pumps (ESP) and upper completion utilizing dual derrick drillship rigs in deep water wells. The availability of a second deck to assemble, test and rack long assemblies brings the possibility to conduct a safer, efficient and reliable operation. The experience in Brazil running complex completions and high horsepower ESPs shows how important is to implement initiatives to reduce rig time. The main objective of the new process is to have every completion tool readily available in the drilling deck, requiring minimum time to connect it to the completion string. In the standard process, the tool sits in the pipe deck until completion string reaches its set position and only then the equipment is brought into the rig floor to be serviced and made up to the completion string. The methodology to assemble ESP and completion tools offline in the auxiliary derrick was developed in partnership with the operator, the service company, and the drilling rig contractor. The offline preparation concept was considered as part of the completion design phase analyzing every step of the upper completion run, looking for efficiency improvement and reduced total rig time. The modern automated pipe handling system was used to manipulate the long and heavy assemblies from the auxiliary deck to the racking system and from the racking system to the main deck without any safety concern, and with minimal human intervention. Eight deep-water operations were completed in Brazil using the new concept and the results brought important rig time reduction in the upper completion running time. The tools that were part of the completion included DHSV, permanent downhole gauges, chemical injection valves, 1600 HP ESP system and tubing test valves. The new process allows the team to service equipment without the usual operation rush reducing installation related failure therefore increasing equipment reliability. The methodology presented on this paper contributes to oil industry as a field-proven reference for offshore ESP and completion deployment technique reducing HSE exposure and total well construction cost. This is particularly important for deep and ultra-deepwater projects which are associated with high intervention costs. Dual derrick rigs were designed with focus to improve drilling operations and after the new process development, the modern robotized machinery empowers ESP and completion activities with improved efficiencies.

"Successful Deployment of Drill Through Turbine Casing Reamer Shoe in Longest Challenging Intermediate Sections on Abu Dhabi Jack Up Operations." In ADIPEC.

Full textAbstract:
Abstract The trial of a turbine powered Motorized Reaming Shoe (MRS) was conducted on two fields offshore Abu Dhabi involving the running of 9-5/8″ casing to planned depths in long intermediate sections. The trials involved running casing in the longest12-1/4″ sections to date on each field. This paper will elaborate on detailed parameters, Motorized Reaming Shoe features and operating practices recorded while reaming through multiple restrictions with a cumulative length of more than 200 ft, across various formations, successfully running casing to the planned depth. It will also elaborate on casing cementing and shoe-track drilling operations where MRS were deployed. Referring to the average NPT duration of similar incidents, this initiative has saved 6 to 7 days of operation (eliminating requirement to pull the casing, perform a wiper trip, and re-run back the casing). This is estimated at an average of approximately 1M$ cost savings per NPT event. The failure to run casing to section TD with the MRS in one of the trial jobs is also analyzed including detailed operational learnings and design changes that could positively impact running long casing strings in complex wells. This paper details the technical features and potential benefits of Turbine Powered Reaming Systems, how the trials were conducted and their impact on de-risking casing deployments, with specific reference to application in long intermediate casing sections offshore Abu Dhabi.

Full textAbstract:
The mechanical friction of liner operations is investigated and compared to what is expected for a conventional drill pipe. In addition the cuttings transport efficiency for realistic conditions is studied. The work is also relevant for running completion strings. This article is based on results from laboratory scale flow loop for drilling applications. Sand particles were injected while circulating the drilling fluid through the test section in some of the tests. The procedures used to conduct the experiments are explained and experimental results and observations are discussed. The drilling fluids and additives in these experiments are similar to those used in in fields on the Norwegian Continental Shelf (NCS). Friction coefficient is calculated from the measured torque for different flow velocities and rotational velocities and the force perpendicular to the surface caused by the buoyed weight of the string.

Full textAbstract:
Abstract The recent industry downturn has forced operators and contractors to re-think and look at different ways to reduce costs while improving the complete well delivery process. Compounding challenges are longer reservoir sections with more complex well trajectories and tighter geological constraints. These complex drilling challenges have been successfully completed in the past, thru use of high-speed Wired Drill Pipe (WDP) telemetry (Schils et al. 2016; Teelken et al. 2016), where the WDP telemetry enabled bi-directional high-speed data transmission to and from downhole tools at speeds up to 57,600 bps (Olberg et al.2008). Whilst the use of WDP telemetry within the ‘drilling phase’ of the well delivery process has become more accepted and implemented globally, providing improved performance and wellbore placement, the use of WDP during the ‘completions phase’ has never been attempted. That is, till today. This paper focuses on the use of WDP during the ‘completion phase’, discussing the first ever application of the battery operated Remotely Operated Completion System (ROCS) on WDP, used offshore North Sea, for umbilical-less Tubing Hanger installation. The ROCS consists of redundant controls architecture and pumps to operate the electrical and hydraulic functions and read gauges. Thru use of the highspeed WDP telemetry, the ROCS is controlled in real-time from topside to operate the Tubing Hanger Running Tool (THRT), Tubing Hanger (TH), downhole functions and downhole gauges, eliminating the need for the traditional umbilical deployed within the Marine Riser. The WDP operated ROCS allows for a simplified system mobilization and operation, reducing total number of rig days and costs significantly. The main advantages that will be discussed and shown include: Eliminating the Electro-Hydraulic umbilical and handling equipment (costly associated equipment) Reduces personnel in red zone (umbilical-less: no clamping) Reduces/Eliminates rig interfaces, (such as Workover Control System (WOCS) container reducing the deck space demand, increasing rig flexibility) Ready to Run (ROCS including THOJ/THRT (Tubing Hanger Orientation Joint/Tubing Hanger Running Tool) tested and mobilized already connected to the TH Significantly reduces risk of Waiting on Weather Real-time readings local to tool, (accurate volumes and pressures, no umbilical influence) The system has been used for horizontal and vertical completions and can operate different running tools, offering field proven benefits for the industry.

Full textAbstract:
This paper will demonstrate how a novel drill pipe conveyed casing and cement evaluation tool can change the way operators approach well integrity decisions through the well life cycle. Through field test results we will demonstrate how operators can improve efficiency, reduce rig time and personnel on board, improve safety of operations and reduce the risk of non-productive and invisible flat time through the application of what is actually not a new technology, or measurement physics but an adaptation in mode of conveyance. The new drill pipe conveyed tool can be run anytime drill pipe is utilized in the well. A radial distribution of ultrasonic transducers arranged on the circumference of a drill collar allows for full azimuthal interpretation of the casing and cement whilst rotating the drill pipe. Analysis of the acquired data allows for interpretation of caliper, thickness and an evaluation of the material in the annular space behind the casing. Additionally, the tool can provide casing collar location in real-time and has the ability to orient downhole devices such as whipstocks, perforating guns and oriented cutters. We will demonstrate through case histories the range of applications of this technology both in recorded mode and in real-time decision making to provide solutions where well integrity measurements are critical in solving problems throughout the well life cycle. Direct comparisons with wireline will demonstrate the efficacy of the technique. Real-time examples of casing collar location (CCL) show the need, especially in deviated and deep wells of running CCL on the actual operation to correctly position devices downhole and eliminate the depth discrepancies that can arise from comparison of wireline and drill pipe conveyed techniques. Examples conclusively demonstrate that the tool can be run in parallel with existing operations to minimize rig time and eliminate the need for a dedicated, standalone wireline operation. Additionally, we will discuss the advantages and disadvantages of drill pipe deployed well integrity measurements and the technology advances used to overcome some of the inherent challenges of this technique.

Full textAbstract:
Coiled tubing is utilized in a variety of oil well operations. For applications such as drilling, completions, and remediation, coiled tubing offers the benefits of reduced costs, increased insertion speed, and reduced environmental impact. Coiled tubing possesses a limitation, however, in that it can buckle in service causing damage to the tube and disruption of operations. There have been numerous papers published during the last 50 years on helical buckling. Numerous fast running engineering codes have been developed to determine the onset of sinusoidal buckling, helical buckling, and lock-up of drill pipe in a wellbore, with particular emphasis on coiled tubing. We provide a methodology for evaluating the complete nonlinear mechanical behavior of coiled tubing insertion from a first-principles finite element modeling perspective. Using this approach the buckling, post-buckling, and lock-up behavior of the drill pipe can be studied. Additionally, post lock-up methods such as vibration loading and downhole lubrication can also be evaluated.

Full textAbstract:
Abstract This paper describes the design, implementation details, and the added value of deploying a 15 kpsi Multi-Stage Fracking (MSF) system with an open hole (OH) metal expandable packer. The system would be an additional enabler for successful OH MSF system deployment, especially for wells with concerns over wellbore stability (pack off and/or washouts), getting stuck while running with the completion string to the deployment depth and in Extended Reach Drilling (ERD) wells. The system used four (4) stages deployed in a 5-7/8″ open hole with a length of 3,000 ft. The completion equipment was successfully deployed. Rigless activities commenced by fully expanding the packers (with 12,400 psi), before the multistage fracturing was conducted successfully. The slim Outer Diameter (OD), the ability of drill pipe rotation, the 15 kpsi fracturing capabilities in hole size up to 6.5 inches and the lack of internal moving parts like sleeves or mandrels; enabled the system to deliver the fracking capabilities required with challenging OH conditions. The system provided reservoir compartmentalization with 15 kpsi capabilities between different stages, 15 kpsi fracturing capabilities in hole size up to 6.5 inches and slim outer diameter to enable the deployment of the completion string into challenging open hole conditions. Furthermore, the system has the ability of drill pipe rotation to enable the deployment of the completion equipment to overcome any obstruction while running in hole and no internal moving parts, which lessen the mechanical failure risks. The 15 kpsi MSF with metal expandable frac packer system has the following novel features in wells with wellbore stability (washouts) concerns, where the 15kpsi fracturing capabilities in hole size up to 6.5 inches, as well as long seal length. As for wells with wellbore stability (pack-off) concerns, the system provides relatively slim OD, for smoother running and, that, can be helpful in wells with differentially stuck concerns. Also, it provides better reliability and robustness, as there are no internal moving parts.

Full textAbstract:
Abstract For years the drilling industry has used sour service drill pipe within a narrow set of specifications and industry guidelines. That left room for original equipment manufacturers (OEM) to have customization on an iterative basis, which resulted in a wide product offering to fulfill operator needs. While this method worked, it did not lead to building the product in the most efficient and economical manner. As a result of this product diversity, drilling engineers could specify the best product to deliver their projects when running drilling models, only to have to redesign it around what is effectively available on rigs or for rental. This disconnect puts pressure on the industry players and is the result of a lack of standardization. We wiped the board to provide a simple solution that is more suited to allow alignment between operators, contractors, and rental companies. The new philosophy is based on the National Association of Corrosion Engineers (NACE) MR0175-2015 severity diagram, where environmental severity is defined in regions (1, 2, and 3), which have been used by oil companies’ engineers for their oil country tubular goods (OCTG) product selection. Even though the drill string will not be exposed to the well fluid for the same extended time and is surrounded by a more forgiving medium, the drilling fluid, the diagram allows a segmentation of customer's needs. This framework helped define targeted product properties. A research and development (R&D) and industrialization test campaign could then be started to confirm that sound product configurations could be offered with targeted properties. The study also explored the limitations imposed on connection make-up torque in a sour gas environment relative to the NACE severity diagram. Emphasis was given on methods to increase the make-up torque, which is needed to deliver the most extended reach wells that are now commonplace. The result of this two-year development campaign is a short list of grades with an optimized balance between pipe subcomponents strength and sulfide stress cracking (SSC) resistance. Region 1 (mild severity) products will offer as much tension and torque as possible, matching or exceeding these of API products, including excellent resistance to SSC, thus making drilling operation safer. Region 2 (medium severity) will offer products with medium to high strength and enhanced SSC resistance. Finally, region 3 (high severity) products will be aligned with the industry specifications for maximized SSC resistance and lower strength. This paper discusses a proactive approach that contrasts with a historical, more reactive one. As the drill stem technology leader, we saw an opportunity to drive this initiative that will benefit the drilling industry by offering a more natural way to select drill stem products. For the first time a sour service product range aligns with the needs of drilling engineers and the inventory of their selected service companies.
