Abstract:

Developing a forecasting model for oilfield well production plays a significant role in managing mature oilfields as it can help to identify production loss earlier. It is very common that mature fields need more frequent production measurements to detect declining production. This study proposes a machine learning system based on a hybrid empirical mode decomposition backpropagation higher-order neural network (EMD-BP-HONN) for oilfields with less frequent measurement. With the individual well characteristic of stationary and non-stationary data, it creates a unique challenge. By utilizing historical well production measurement as a time series feature and then decomposing it using empirical mode decomposition, it generates a simpler pattern to be learned by the model. In this paper, various algorithms were deployed as a benchmark, and the proposed method was eventually completed to forecast well production. With proper feature engineering, it shows that the proposed method can be a potentially effective method to improve forecasting obtained by the traditional method.

Abstract:

The selection of effective surfactants potentially can mobilize oil up to 50% of residuals in mature carbonate oilfields. Surfactants’ screening for such oilfields usually is complicated by the high salinity of water, high lipophilicity of the rock surface, and the heterogeneous structure. A consideration of features of the oilfield properties, as well as separate production zones, can increase the deep insight of surfactants’ influence and increase the effectiveness of surfactant flooding. This article is devoted to the screening of surfactants for two production zones (Bashkirian and Vereian) of the Ivinskoe carbonate oilfield with high water salinity and heterogeneity. The standard core study of both production zones revealed no significant differences in permeability and porosity. On the other hand, an X-ray study of core samples showed differences in their structure and the presence of microporosity in the Bashkirian stage. The effectiveness of four different types of surfactants and surfactant blends were evaluated for both production zones by two different oil displacement mechanisms: spontaneous imbibition and filtration experiments. Results showed the higher effect of surfactants on wettability alteration and imbibition mechanisms for the Bashkirian cores with microporosity and a higher oil displacement factor in the flooding experiments for the Vereian homogeneous cores with lower oil viscosity.

Abstract:

As a mature tertiary oil recovery technology, polymer flooding has been widely used in domestic oilfields, especially in Daqing oilfield, its polymer flooding production has reached more than 25% of total output. Therefore, there are important theoretical significance and application value to do further research of polymer flooding mechanism and use to guide the production. In order to understand the mechanism of polymer flooding, polymer flooding oil film based on the decrease of residual oil range is the biggest, established the dynamics model of polymer solution displacement of rock wall oil film under the condition of tensile and shear flow.

Abstract:

Due to the influence of long-term waterflooding, the reservoir physical properties and percolation characteristics tend to change greatly in offshore unconsolidated sandstone reservoirs at ultrahigh water-cut stage, which can affect the remaining oil distribution. Remaining oil characterization and proper development strategy-making are of vital importance to achieve high-efficiency development of mature reservoirs. The present numerical simulation method is difficult to apply in reservoir development due to the problems of noncontinuous characterization and low computational efficiency. Based on the extended function of commercial numerical simulator, the time-varying equivalent numerical simulation method of reservoir physical properties was established, and the research of numerical simulation of X offshore oilfield with 350,000 effective grids was completed. The results show that the time-varying reservoir properties have a significant impact on the distribution of remaining oil in ultrahigh water-cut reservoir. Compared with the conventional numerical simulation, the remaining oil at the top of main thick reservoir in X oilfield has increased by 18.5% and the remaining oil in the low-permeability zone at the edge of the nonmain reservoir has increased by 27.3%. The data of coring well and the implementation effect of measures in the X oilfield are consistent with the recognition of numerical simulation, which proves the rationality of numerical simulation results. The new method is based on a mature commercial numerical simulator, which is easy to operate and has reliable results.

Abstract:

The waterflooding development of Oilfield fringe area and scattered blocks are restricted by the existing pipe network design and pipeline transportation distance and so on. In order to improve the development effect of these blocks, by using advantages of ESP including high head, range capacity and mature technology, technology of exploiting and waterflooding in one well with ESP was discussed. Then, some key problems were settled such as sand prevention, sealing, downhole monitoring of process parameters, structure design and so on, and three process schemes were summarized including exploiting the upper layer and waterflooding the lower layer, exploiting the lower layer and waterflooding the upper layer and downhole pressurized injection. The technology proposed by this article has achieved good results proved by field applications. The success of the technology provides an economical and reliable energy supply technology for oilfield development, and has a broad market prospect.

Abstract:

AbstractThe Balmoral Oilfield is a mature asset in its final phase of production. Associated with the Balmoral development have been the less significant Glamis and Stirling Fields. Each field is different from the perspective of geology and many other issues. Balmoral is a typical Paleocene oilfield with good water drive from a large regional aquifer. Interestingly this was not recognized at the start of the development when water injection facilities were commissioned. Glamis is a smaller field of Late Jurassic age containing somewhat lighter oil than Balmoral. Water injection has been necessary to maximize recovery in this field. Stirling is one of the few fields in the North Sea to produce commercially from the naturally fractured Devonian Sandstone. This field is developed by a single horizontal well.Balmoral oil recovery has significantly exceeded original expectations, whilst Glamis and Stirling have produced as much as expected.

Abstract:

This chapter discusses the origins of Britain’s postwar oil strategy, which aimed at making Britain independent of imports from other great powers, especially the United States. It begins by reviewing Whitehall’s increasing preoccupation with oil as a matter of national security before 1914, including the Royal Navy’s shift to oil and the government’s purchase of a majority of shares in the Anglo-Persian Oil Company. It then examines the British experience during and immediately after World War I, when officials began pursuing two of the key objectives of British strategy—securing British majority ownership of Shell and the oilfields of Mesopotamia. The chapter concludes with an assessment of how oil influenced Britain’s war aims in the Middle East and Anglo-American competition over the region’s oil.

Abstract:

Abstract CNOOC Iraq Limited (CILB) operates the Missan oilfield in Iraq, which consists of three oilfields: Buzurgan oilfield, Abu Gharib oilfield and Fauqi oilfield. To maximize production from the field it has been necessary to overcome different challenges related to asphaltenes (tubing deposition, formation damage, emulsions) – firstly by properly understanding the fluid behaviour, and then by developing and implementing mitigation strategies. To understand the asphaltene stability of the reservoir fluids, an isothermal depressurization study was performed on a monophasic bottomhole sample from the reservoir's main production unit. Asphaltene Onset Pressures (AOPs) were identified and used for tuning an equation-of-state model to generate an asphaltene precipitation envelope (APE). Modelling software was used to calculate pressure-temperature profile of fluids both in the near wellbore region and production wells and determine if they entered the APE. This was reviewed against historical field data to assess if asphaltene issues were predictable. Common fluid property screening tests (e.g. De Boer plots, Colloidal Instability Index) under-predicted the occurrence of asphaltene precipitation in the oilfields. When fluid pressures and temperatures in the reservoir and well environment were compared against the modelled APE, they showed the reservoir fluids passing through the asphaltene instability region for most wells, indicating a risk of deposition in the tubing and in the formation. Comparing predictions with field data highlighted that precipitation of asphaltenes does not always result in tubing deposition and additional factors such as watercut and oil viscosity need to be considered. Other fluid-related issues, such as stable emulsions and formation damage, have been observed in the field and require managing. Results from this study show that these can be explained in terms of asphaltene stability issues arising from fluid P/T behavior and interactions with water. The importance of drawdown management, already practiced by the field operator, is shown to be a key tool for managing and controlling asphaltene issues. The value of optimizing solvent-based stimulations and retaining the ability to stimulate ESP-lifted wells is also demonstrated. Measuring asphaltene stability using virgin reservoir samples, and applying fluid screening tests, are common activities during new field appraisals. The results inform high value decisions, ranging from completion design to reservoir management strategy. This study, conducted on a mature field with known production history, shows how results from fluid characterisation studies relate to actual experience of asphaltenes during production. The use of fluid studies in diagnosis and treatment of operational challenges is also demonstrated.

Abstract Abundant faults, long oil-bearing intervals (up to 500m), and diverse fluids including conventional oil and heavy oil, result in P oilfield became one of the most complex oil fields in the Bohai Bay. The main characters ofinitial development plan are directional well with commingle production, open hole completion, large draw down, high oil production rate, and reverse nine-point well pattern. At present, the oilfield has entered a stage of high water cut, with average water cut more than 85%. What can we do next, decommissioning or rebirthing? An integrated solution was proposed to redevelop the oilfield which focus on the layers’ subdivision, the fine description of the sand body,a large number of horizontal wells on the top of the water-flooded layer are used to tap the potential, increase the water injector to transform the stream lines and rebuild the reservoir pressure, and search for potential sand bodies to increase reserves.

Abstract:

Abstract To remain economical, mature offshore oil fields require unique, time-efficient and cost-efficient drilling and completion operations for each well. This paper is a case study of a rapid selection method for determining the operational process for each offshore oil well candidate and its application in the Zhaodong oilfield. In mature oilfields, maintaining production requires drilling and completing sidetrack wells. There are 3 key steps to rapidly selecting the most suitable drilling, completion and operational strategy for each well. First, review historical production data and operational costs to set production targets for each well. Second, evaluate the potential drilling and completion operations both technically and economically to achieve the target. Third, optimize the selected operations based on prior field application and production results. This process was applied with newly sidetracked wells in the Zhaodong oilfield. The wells were either completed using a multi-zone cased hole fracturing technique or an open hole completion technique, per the selection process. One candidate well completed with the multi-zone fracturing technique had a daily production rate of 134 tons of oil, and another candidate well completed with an open hole technique had a production rate of 236 tons of oil. These two wells were the most prolific in the Zhaodong oilfield. Using relatively basic engineering work integrated with simple economic calculations, this methodology is far less complicated and costly than computer simulation modeling for the operator. The performance in the Zhaodong oilfield reinforces this methodology used for selecting the proper candidate and completion process, providing more value and confidence for offshore operators.
