Abstract One of the main objectives for the successful development of the majority of producing oil and gas companies in western Siberia is the development of the Achimov strata. It contains a commercially attractive volume of reserves. This reservoir in most oilfields belongs to the hard-to-recover oil - it has a permeability of less than 2 mD. In this regard, the development of the Achimov strata is impossible without carrying out measures for production enhancement. Where most common is hydraulic fracturing. The wells tests with hydraulic fracturing conducted at the Salym group of fields showed that not all reserves are economically attractive, and the decline rate in the first year is extremely high. In this connection, the needs of finding more effective solutions for the production enhancement has become urgent. This article describes the results of pilot work on two wells using a mixture based on a high-viscosity friction reducer (HVFR) as the hydraulic fracturing fluid. The work was carried out at wells where hydraulic fracturing based on cross-linked gel had already been performed and the wells were launched into production. The results of the work, the lessons learned and the analysis of the subsequent production of these wells is the purpose of this work.

Hydraulic fracturing has been booming in the last decade in the United States. While natural gas extraction and production has improved the national energy security, it has raised questions around the water security of those communities where extraction is taking place. Both scientists and residents are concerned about hydraulic fracturing’s impacts on surface- and groundwater, especially regarding how hydraulic fracturing impacts residents’ access to safe household well water. In the past decade, the Marcellus Shale has been developed in Northwestern West Virginia, yet the human geography dimensions of oil and gas extraction in West Virginia remain to be investigated. This article, based on 30 in-depth interviews, explores household groundwater insecurity due to hydraulic fracturing experienced by residents (i.e., mineral owners, surface owners, and concerned citizens) in Northwestern West Virginia. The concept of water affect is used to attend to the emotional and subjective dimensions of water security by unveiling the power, emotional struggles, and mental stress inherent in water testing practices and environmental regulation around hydraulic fracturing. Water testing is typically conducted by contractors hired by oil and gas companies, but it is mired in delayed test results and incorrect testing procedures, triggering residents’ negative feelings toward oil and gas companies. This article furthers the understanding of water security, commonly defined in terms of individual access to adequate water quality and quantity, by studying Appalachian residents’ anxieties about well water contamination and uncertainty around the long-term water impacts of hydraulic fracturing. By investigating the uneven power relations around groundwater in West Virginia, the emotional experiences and responses are articulated to further the notion of water affect as impacting household groundwater security.

Abstract Since the arrival and advancement of horizontal drilling and hydraulic fracturing (hydrofracturing) technologies, developing and producing unconventional formations like the Bakken Formation have become a mystery solved for operators in North America. This has also made unconventional reservoir assets the central focus of the oil and gas/energy industry at the state, national, and global levels. However, the produced water from these activities has high salt contents (∼110,000 to 350,000 ppm) total dissolve solids (TDS) in the Bakken Formation) and poisonous if untreated and in contact with the environment. The most common disposal method in the Bakken Formation is deep injections into disposal wells. However, there have been some fears that continuous injections, in addition to contaminating the ground water, could potentially lead to seismic activities either at the time of injection or in the near future. If treated and made fit for its respective applications, this water could be reused in the hydrofracturing process, thereby reducing operator costs of water acquisition and disposal. In addition, it could be used for power generation or to support coal mining and irrigation. Previous studies have discussed various means of improving the quality of the produced water. However, none have been able to cope with the issue of wastewater and residual oil high in TDS. This paper aims to study all relevant means that allow the Bakken Formation to produce water that can be used as an alternative based fluid for use with polymers like high viscosity friction reducers (HVFRs) to make hydraulic fracturing fluids that will be stable with reservoir conditions and able to reduce environmental footprints and operating costs. This research presents an experimental investigation using the Bakken Formation's hypersaline water with HVFRs. This work includes experimental research divided into base case scenarios that serve as a standard for comparison of the effectiveness of the other cases. The results show that the Bakken water high in TDS treated with higher dosages (4-8 GPT) of HVFRs withstand the effect of hardness, salinity, and heavy metals and remain stable at various shear rates (66-330 s−1). No treatment was done on the Bakken produced water except filtration and dilution.

With every year, the application of merges and acquisitions strategy becomes more and more topical for Russian companies. One of the most topical issues is carrying out the analysis of efficiency of M&A transactions that is also confirmed by increasing the number of works in the field of assessment of efficiency of M&A transactions of companies. In this article, the main methods of assessment of efficiency of M&A transactions, and also possibility of use of the DEA method in determining efficiency of transactions of the oil and gas companies are considered for example. The comparative analysis of application of traditional methods and the DEA method using example of an assessment of efficiency of acquisition of JSC Rosneft is carried out. Results of the analysis showed that it is necessary to carry out a complex assessment of productivity of the M&A transaction, using some methods and assessment approaches, since the DEA method not always works in a section of an assessment of efficiency before and after the transaction. So, according to the given calculations, the effect of acquisition in the first year after acquisition was positive (0,001%), but by 2014 became 0,9%. Profitability of assets as started decreasing, and two years later the total change became 5%. Thus profitability of the capital increased in the first year by 26% however in a year this value decreased. At the same time, this method is applicable for an express choice of the companies purposes from a large number of the companies. The sequence of steps is developed for DEA method application in an assessment of efficiency of carrying out transactions on merges and acquisitions, and also a technique of definition of DMU for an assessment of efficiency of one transaction within DEA method use that gives to research the high practical importance. Recommendations about express selection of the companies purposes for carrying out the transaction of M&A are made.

Abstract Currently oil and gas companies are spending billions of dollars on digitalization efforts. One important aspect of a project that needs to be digitized are requirements. Most oil and gas companies receive project documentation and requirements as PDF files. Receiving PDF documents make it very difficult for companies to manipulate the content to identify which parts of the document are requirements and which parts are just background information. In addition, documents that contain requirements have poorly written requirements that are ambiguous, and can have many interpretations, making it difficult to show compliance. To solve the issues caused by poorly written requirements and receiving PDF files instead of receiving requirements in a more usable format, the solution is to rewrite the requirements and use a requirements management (RM) tool to put the requirements in a database. The American Petroleum Institute (API) 17O 2nd Edition document and a representative list of High Integrity Pressure Protection System (HIPPS) product requirements are used to show the benefits of using a requirements management tool. This paper will describe the prerequisites prior to selecting an RM tool, show how using a requirements quality analyzer tool can aid in preparing requirements to be imported into an RM tool, demonstrate the main benefits of using an RM tool in a project context, and discuss lessons learned from adding an RM tool to a document-based project.

Induced Seismic Activity

High-volume hydraulic fracturing combined with horizontal drilling has “revolutionized” the United States’ oil and gas industry by allowing extraction of previously inaccessible oil and gas trapped in shale rock [1]. Although the United States has extracted shale gas in different states for several decades, the United Kingdom is in the early stages of developing its domestic shale gas resources, in the hopes of replicating the United States’ commercial success with the technologies [2, 3]. However, the extraction of shale gas using hydraulic fracturing and horizontal drilling poses potential risks to the environment and natural resources, human health, and communities and local livelihoods. Risks include contamination of water resources, air pollution, and induced seismic activity near shale gas operation sites. This paper examines the regulation of potential induced seismic activity in Oklahoma, USA, and Lancashire, UK, and concludes with recommendations for strengthening these protections.

Subject. This article discusses the practice of ensuring the economic security of oil and gas companies operating under the terms of production sharing agreements, where minerals are the object of security. Objectives. The article aims to justify the need to apply professional judgment in the organization of reliable accounting of minerals, explored and extracted under the terms of the production sharing agreement implementation, to avoid various risks to the entity's economic security. Methods. For the study, I used the methods of deduction and modeling. Results. The article presents proposals to arrange accounting of intangible exploration assets (geological information on mineral reserves) and finished products (the part of the extracted minerals owned by the investor and the part owned by the State). Conclusions. As strategic minerals, oil and gas are the targets of various economic risks. Professionals familiar with the specifics of accounting operations in the implementation of the production sharing agreement should be prepared to prevent these risks. The results obtained can be used to design accounting policies and develop local regulations on the tasks and functions of the economic security service of the organization implementing the production sharing agreement.
