Abstract In the Russian Federation, the main gas reserves are located in Siberia, and they are also present in the North Caucasus and the Black Sea basin. The largest gas fields in Russia are in harsh climatic conditions and drilling remains the main method of their development. Prior to its use, a preliminary study of rocks is required. Safety rules in the oil and gas industry are always relevant, taking into account, as a rule, harsh natural and climatic conditions in promising gas production regions. The forecasts for the growth of Russia’s gas industry varied greatly depending on the overall future prospects for the development of the country’s economic situation. This would entail examining the risks posed by the combined effects of natural and man-made factors on the environment and human health in areas affected by the gas industry. The most effective and widespread method of gas production, but at the same time the most traumatic of the articles is drilling. The article presents the main reasons for the injury of workers during drilling operations: technical, sanitary, organizational and psychological. Based on the causes of injuries in the performance of brown work, the authors developed and presented in the article a number of measures aimed at the pre-rotation or reduction of the impact of dangerous and harmful factors on workers when drilling gas wells. Gas mixtures of explosions and fire hazards, as well as when inhaled, can lead to poisoning of workers or an emergency. The development of a list of measures to protect against peacetime emergencies for gas facilities is presented in the second part of the work in the form of organizational and engineering measures. The list of measures for protection in peacetime emergencies for gas facilities is aimed at ensuring industrial safety, emergency resistance of hazardous production facilities, creating safe working conditions during drilling operations.

Introduction/Aim Carbon monoxide (CO) is a gas produced by incomplete combustion of carbon compounds and is a leading cause of poising throughout the world. The objective of this paper is to analyze 5 cases of acute carbon monoxide poisoning in petroleum industry workers, occupying a shared accommodation and to present diagnostic, therapeutic and preventive measures. Case report the workers had to be treated by the emergency medical service during the night for health problems arising from carbon monoxide inhalation from a faulty installation. Venous blood samples were collected to measure the concentration of carboxyhemoglobin (COHb) and gas analyses were done upon admission and 120 minutes later. They were treated with parenteral therapy and oxygen by mask, and they made a complete recovery. Conclusion Faulty installation of a gas-powered heating system caused acute carbon monoxide poisoning in 5 people occupying the space. After 120 minutes in a closed environment, the carbon monoxide concentration was high enough to cause a significant increase of COHb in the venous blood. Prompt diagnosis and adequate therapy are crucial to ensure a favorable treatment outcome. Preventive measures, such as educating workers and introducing health and safety measures into the work environment are extremely important in preventing accidents such as these.

Abstract Oil and gas industry processes are associated with significant expenditures and risks. Adequacy of the decisions on safety measures made during early stages of planning the facilities and processes contributes to avoiding technological incidents and corresponding losses. Formulating straightforward requirements for safety instrumented systems that are followed further during the detailed engineering design and operations is proposed, and a mathematical model for safety system design is introduced in a generalized form. The model aims to reflect the divergent perspectives of the main parties involved in oil and gas projects, and, therefore, it is formulated as a multi-objective problem. Application of black box optimization is suggested for solving real-life problem instances. A Markov model is applied to account for device failures, technological incidents, continuous restorations and periodic maintenance for a given process and safety system configuration. This research is relevant to engineering departments and contractors, who specialize in planning and designing the technological solution.

This paper provides a brief update on some of the key environmental issues that arose during 2009. In Queensland, activity is dominated by coal seam gas projects and specifically coal seam gas (CSG) to liquefied natural gas (LNG) projects. Environmental milestones for these projects are discussed, and the State Government’s response policy and regulation development response is reviewed. The progress of the more conventional LNG projects in Western Australia and the Northern Territory is also discussed. The final report on the mandated ten year review of the Environment Protection and Biodiversity Conservation Act 1999 was released in December 2009. Seventy-one recommendations were made, and some key recommendations related to our industry are discussed here. Climate change has again dominated the media, with the United Nations Climate Change Conference held in Copenhagen in December 2009. In Queensland, the Government released a paper that presented a range of strategies and policies, building on a number of existing schemes and introducing new measures. Gas is identified as a key transitional fuel while low emission coal technology and emerging renewable energy sources are being developed. Greenhouse gas legislation is continuing to be developed across several states, but subordinate legislation is yet to be finalised. In Victoria, submissions on the Greenhouse Gas Geological Sequestration Regulations closed in October 2009, and the Greenhouse Gas Geological Sequestration Act 2008 came into effect on 1 December 2009. In March 2009, ten offshore acreage releases were made under the Commonwealth legislation; however, the closing date for submissions is dependent upon the development of the regulations. South Australia passed an Act amending the Petroleum and Geothermal Act 2000 on 1 October 2009 to allow geosequestration. A number of reviews of the regulatory framework or the administrative systems associated with the upstream oil and gas sector have been completed in the last decade. All these reviews make similar findings and recommendations, and most recently the Jones Report, tabled in Western Australian Parliament on 12 August 2009, found that most key recommendations from previous reports and reviews had not been addressed or properly implemented. There seems to be little point in undertaking regulatory and system reviews that consistently make similar findings, if these findings are never addressed. The hurdles to implementation of key recommendations need to be identified, so that progress can be made in improving the approvals processes for the industry, and improving the environmental outcomes.

Problem statement. Taking into account the world experience, the most effective is risk managementbased on achieving a certain level of safety, a balance of benefits and costs within a separate facility, territory, industryand the state as a whole. Today, risk management mechanisms aimed at reducing their values have not received widepractical application in the oil and gas industry of Ukraine. Thus, a quantitative risk assessment is used only in relationto industry workers during the execution of work, and a qualitative risk assessment in relation to machines,mechanisms, equipment is not used at all, including the likelihood of a positive compensatory impact of measures toУкраїнський журнал будівництва та архітектури, № 4 (004), 2021, ISSN (Print) 2710-0367, ISSN (Online) 2710-0375 46 counter security threats is not predicted, as well as technical condition and safety of facilities, primarily those that areoperated with defects. At the same time, imperfection of regulatory legal acts and inconsistency at the state and industrylevel of risk management methods do not allow the industry to achieve risk levels corresponding to the levels ofeconomically developed countries. The need to introduce conceptual foundations for ensuring the safety of the industry(management of the risk of accidents) is integral to labor protection, industrial, public, man-made, environmental safetyand energy resource efficiency, caused by the presence in the industry of a large number of organizational and manmade hazards.

Full textAbstract:
The aim of this study was to identify, discuss and make recommendations regarding causal factors associated with injuries and accidents among seafarers and rig workers providing support to the WA offshore oil and gas industry. These incidents cause significant personal and economic burdens for employees, employers and the community in general.
A sample of 484 participants were recruited from a workforce of 9800 employees (approximately 5%). Participants were stratified into 2 cohorts; those who had suffered injury (286 – study group) and those who had not (198 - controls).
Data from the study group were stratified into oilrig workers and vessel seafarers. A one-way analysis of variance revealed that the injury incidence rate for the seafarers in the study group was significantly higher (mean 14.4 injuries) in the first quarter of each multi week work period ( "swing") (P=0.001), compared to means of 4.125 and 2.44 and 4 for the subsequent quarters. For the oil rig workers, the mean injury incidence rates across the four quarters remained similar.
It was recommended that a safety officer be assigned to each vessel to support workers for the 1st quarter of each swing. Implementation of this practice has been trialled in another study leading to a reduction in the number of incidents over a 12 month period (Brown, 2009). Other factors that influenced injury incidence rates were age and level of experience, with younger and less experienced workers being more injury prone. Encouraging older, experienced workers to mentor younger employees and to manage their workload according to their physical capabilities will be a useful intervention. The implementation of these recommendations will reduce the injury incidence rate of this unique cohort of employees thus reducing the economic burden of injuries and accidents to the employee, the employer and the community in general.

Full textAbstract:
Surface plasmon resonance sensors that incorporate graphene as one of the layers in the sensor structure have been proven to provide higher sensitivity in the detection of biomolecules, compared to sensors without graphene. Graphene an allotrope of carbon facilitates better adsorption to biomolecule samples due to the carbon-hydrocarbon affinity to biomolecules, thereby resulting in higher sensitive biosensors. Recently, a revolutionary method has been presented, at least in theory for now, that there is still a possibility to increase the sensitivity of the SPR sensors by the application of electric bias across the metal-graphene sensor system. A mathematical treatment to understand the physics of how the electrical bias contributes to an increase in sensitivity is presented in this chapter, using a sensor surface structure comprising of Au-MoS2-Gr. The results indicate that the application of electrical bias across the sensor surface consisting of Gr and other materials provides a method to increase the sensitivity of these biosensors. The scope and impact of this research can be felt in many industries that need sensors either in the food industry for food contamination check, harmful gas detection for environmental monitoring or safety measures, medical diagnostics etc.

Full textAbstract:
Instances of gas accumulation in the subject systems have occurred since the beginning of commercial nuclear power plant operation. NRC Generic Letter 2008-01, “requests that each licensee evaluate its ECCS, DHR system, and Containment Spray system licensing basis, design, testing and corrective actions to ensure that gas accumulation is maintained less than the amount that challenges operability of these systems, and that appropriate action is taken when conditions adverse to quality are identified.” All of the three NPPs have accomplished this evaluation and propose some corrective measures like revision of the operation procedures, installing the venting valves etc. Taipower also committed AEC to establish the acceptable quantity of the gas accumulation and continue to follow the development of gas transport methodologies in the industry. According to the NRC NRR Action Plan TAC.NO. ME3939 GAS MANAGEMENT (March 2011), other safety related systems, in additional to the systems covered by GL 2008-01, also have the gas accumulation issue and therefore must be concerned. This project will develop the numerical evaluation process with two phase flow software to simulate the gas accumulation and the transportation phenomena for the GL 2008-01 systems and validate the results by experimental analysis.

Full textAbstract:
Gas intrusion into safety related systems, such as the Emergency Core Cooling System (ECCS), Decay Heat Removal (DHR) and Containment Spray (CS) system in nuclear power plants is undesirable and has led to pump binding and damaging water hammer events. Furthermore, total or momentary loss of hydraulic performance in safety related pumps has occurred, which has led to pump damage rendering the pumps unable to perform their safety functions or reduce the pump discharge pressure and flow capacity to the point that the system cannot perform its design function. Extreme cases of water hammer can result in physical damage to system piping, components and supports, and possible relief valve lifting events with consequential loss of inventory. The U.S. Nuclear Regulatory Commission (NRC) issued Generic Letter GL-2008-01, “Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems,” requiring U.S. utilities to demonstrate that suitable design, operation and testing measures are in place to maintain licensing commitments. GL-2008-01 outlines a number of actions that are detailed in nature, such as establishing pump void tolerance limits, establishing limits on pump suction void fractions, assuring adequate system venting capability, identifying all possible sources of gas intrusion, preventing vortex formation in tanks and determining acceptable limits of gas in system discharge piping. Regarding one of these issues, GL-2008-01 indicates that the amount of gas that can be ingested without significant impact on pump operability and reliability is not well established and is known to depend on pump design, gas dispersion and flow rate. Each U.S. nuclear power plant licensee is required to evaluate their ECCS, DHR and CS system design, operation and test procedures to assure that gas intrusion is minimized and monitored in order to maintain system operability and compliance with the requirements of the U.S. code of federal regulations 10 CFR 50 Appendix B. Typically, gases get into the safety related systems through a number of mechanisms, such as maintenance, gas desorption, vortex activities, cavitation, etc. This paper discusses the sources of gas into safety related systems and the challenges associated with management of gas voids in these systems. A number of technologies exist that can detect the gas that accumulates in the safety related piping. These technologies are discussed and an integrated approach for monitoring gas accumulation in safety related pipes is presented. Issues such as methods to get rid of gases and venting periodicity are discussed. Industry efforts to address the management of gases in these systems are also presented.

Full textAbstract:
Abstract This paper presents a novel approach to finding solutions to unsafe work practices in oil and gas environments—from manufacturing facilities to offshore platforms. The ‘Center of Excellence’ approach is a stepwise process for classifying safety events and harnessing data to reduce incidents during offshore oil and gas E&P activities. The approach includes identifying focus topics related to unsafe practices, forming cross-functional teams with significant field or impacted personnel participation, developing and implementing measures, utilizing the hierarchy of controls to mitigate the issue, and raising company-wide awareness through training and targeted information campaigns. The Center of Excellence process gives top priority to those activities in order to reduce the highest severity and most frequent safety incidents. The teams are then able to more clearly identify feasible solutions, including engineering controls, training, campaigns, and procedures to contain the hazards. The active engagement and involvement of frontline employees who either work in the field or on the factory floor is critical to understand the daily hazards of their work activities and the success of the Center of Excellence approach. With these employees acting as a champion of the developed solution, other workers are more likely to accept and adopt it in their daily routine. This paper reviews practical examples of how the Center of Excellence approach has led to safer practices in the workplace. Examples include improved safety measures for using tightening tools, which led to more than 50% reduction in hand injuries and other safety incidents. A recent example of using the approach to develop safer practices during manual handling of loads (MHL) is also presented. The examples highlight the benefits of bringing multifaceted teams and multiple industry-accepted safety concepts together to resolve common work safety challenges, which can serve as a blueprint for oil and gas companies to reduce incidents across their enterprise.

Full textAbstract:
Dynamically positioned (DP) vessels are widely used in marine operations in the offshore oil & gas industry. The risk caused by DP vessels’ position loss is not negligible, and managing DP safety in marine operations is indispensable. This paper presents an overall framework for DP safety management in offshore marine operations. It consists of the following three key steps, i.e. 1) Identification of position loss scenarios, 2) Risk analysis in terms of position loss frequency and consequences, and risk evaluation, 3) Mitigation of risk via measures to eliminate the risk, or to reduce the likelihood of position loss, as well as to mitigate the consequence in marine operations given DP vessel position losses. Case studies from DP shuttle tankers and DP mobile offshore drilling units are presented to illustrate key principles in each of the above three steps. Quantitative risk analysis and evaluation approach is highlighted, and the associated challenges are described. Recommendations to further improve DP safety management in offshore marine operations are proposed.

Full textAbstract:
Bowtie diagrams have become a widely-used method for demonstrating the relationship between the causes and consequences of hazardous events following the identification of Major Accident Hazards (MAHs). They are particularly useful for illustrating how safeguarding measures protect against particular threats or mitigate the various consequences of an incident. Bowtie diagrams have been widely used in a range of industries for over twenty years and are widespread in the upstream oil and gas industry, as well as other high hazard industries such as mining and nuclear. Bowtie diagrams are used for a range of purposes. At their simplest, they provide an overview of the measures in place to prevent and mitigate hazardous events, and as such are valuable additions to training programmes. A bowtie diagram provides an excellent platform to show regulatory authorities, trainees and new employees the various threats to a pipeline system, and what barriers are in place to prevent and control major accidents, such that the risks are as low as reasonably practicable. The bowtie process may be used during design, construction, operations and decommissioning. The bowtie for construction is different to that for design and operations, being more to do with occupational safety rather that loss of containment. However, the construction bowtie diagram still plays a vital role in minimising risk. Whilst the typical failure mechanisms for pipelines are generally well-established during operations, bowties have a key role in informing senior management of the measures in place to reduce risk. Furthermore, a large proportion of major accidents may occur at above ground installations (AGIs), and bowtie diagrams provide a mechanism to help management in the protection of personnel and potentially of nearby populations. For both cross-country pipelines and AGIs, the effectiveness of each barrier can be established to ensure that the risk of loss of containment is minimised. More detailed bowties may be used to assist in identifying safety critical elements (SCEs) or safety critical tasks; developing performance standards and defining process safety performance indicators. Often, the hardware shown by the barriers may be considered as SCEs, particularly in the case of effective barriers, such as vibration detection along the right-of-way (RoW) (prevention) or gas detection at AGIs (recovery). Where such barriers are defined as key to a major threat, the bowtie diagram illustrates the importance of good maintenance systems to ensure that the barriers have a high reliability. Thus, by defining the SCEs in a logical manner, bowties may be a key element in managing the risk from a pipeline system.

Abstract In the current oil and gas drilling industry, the modernization of rig fleets has been shifting toward high mobility, artificial intelligence, and computerized systems. Part of this shift includes a move toward automation. This paper summarizes the successful application of a fully automated workflow to drill a stand, from slips out to slips back in, in a complex drilling environment in onshore gas. Repeatable processes with adherence to plans and operating practices are a key requirement in the implementation of drilling procedures and vital for optimizing operations in a systematic way. A drilling automation solution has been deployed in two rigs enabling the automation of both pre-connection and post-connection activities as well as rotary drilling of an interval equivalent to a typical drillpipe stand (approximately 90 ft) while optimizing the rate of penetration (ROP) and managing drilling dysfunctionalities, such as stick-slip and drillstring vibrations in a consistent manner. So far, a total of nine wells have been drilled using this solution. The automation system is configured with the outputs of the drilling program, including the drilling parameters roadmap, bottomhole assembly tools, and subsurface constraints. Before drilling every stand, the driller is presented with the planned configuration and can adjust settings whenever necessary. Once a goal is specified, the system directs the rig control system to command the surface equipment (draw works, auto-driller, top drive, and pumps). Everything is undertaken in the context of a workflow that reflects standard operating procedures. This solution runs with minimal intervention from the driller and each workflow contextual information is continuously displayed to the driller thereby giving him the best capacity to monitor and supervise the operational sequence. If drilling conditions change, the system will respond by automatically changing the sequence of activities to execute mitigation procedures and achieve the desired goal. At all times, the driller has the option to override the automation system and assume control by a simple touch on the rig controls. Prior to deployment, key performance indicators (KPI), including automated rig state-based measures, were selected. These KPIs are then monitored while drilling each well with the automation system to compare performance with a pre-deployment baseline. The solution was used to drill almost 60,000 ft of hole section with the system in control, and the results showed a 20% improvement in ROP with increased adherence to pre-connection and post-connection operations. Additionally, many lessons were learned from the use and observation of the automation workflow that was used to drive continuous improvement in efficiency and performance over the course of the project. This deployment was the first in the region and the system is part of a comprehensive digital well construction solution that is continuously enriched with new capabilities. This adaptive automated drilling solution delivered a step change in performance, safety, and consistency in the drilling operations.

Full textAbstract:
Abstract Oil price is primarily determined by global supply and demand forces as well as governments policies and action or inaction of institutions like OPEC. However, in recent times, it has become evident that public health is a vital factor influencing demand and in turn oil price. In US, oil price reached a negative value for the first time in history by April 2020. Personnel and public health have been shown to have profound effect on operational expenditure (OPEX) of organizations, this in turn affecting the profitability of such organizations. Extra measures involving cost, had to be taken by organizations all over the world to ensure health and safety of their personnel in their sites. In Nigeria, effect of covid-19 measures for companies were, shut in of production, declaration of force majeure on ongoing contracts, slashing of costs, suspension on evaluation of future projects, profile assets for sale, remote/tele working, etc. Huge costs were also incurred as a part of corporate social responsibility for host communities/states where they operate. The consequential outcome is that there are reports of lower than planned profitability and liquidity positions. This paper examines action taken during this covid crisis and their impact on the financial status of their organizations. Using a quantitative and descriptive research design, an online survey has been used to gather information from respondents from different oil and gas companies of cost incurred by them. Secondary data was also obtained from quarterly reports of some companies of the oil majors to show their profitability comparing Q1-Q4 of 2019 and 2020. The paper also appraises action and inaction by corporate/government bodies to stimulate economic growth and help its personnel/citizenry. An attempt is also made to glean experience and lessons from organization that lived through the periods being examined.
