The article considers the most effective and environmentally friendly methods of utilization of associated petroleum gas (APG) for advanced oil and gas companies, as well as the developed method of utilization of associated gas using downhole steam-gas generator. The downhole steamgas generator burns APG at the bottomhole in the combustion chamber, and the combustion products - nitrogen and carbon dioxide - are supplied to the oil reservoir. A method for calculating the theoretical amount of air and combustion products is proposed.

Cooper Basin

The Tirrawarra Oil and Gas Field, discovered in 1970 in the South Australian portion of the Cooper Basin, is the largest onshore Permian oil field in Australia. Development began in 1981 as part of the $1400 million Cooper Basin Liquids ProjectThe field is contained within a broad anticline bisected by a north-south sealing normal fault. This fault divides the Tirrawarra oil reservoir into the Western and Main oil fields. Thirty-four wells have been drilled, intersecting ten Patchawarra Formation sandstone gas reservoirs and the Tirrawarra Sandstone oil reservoir. Development drilling discovered three further sandstone gas reservoirs in the Toolachee Formation.The development plan was based on a seven-spot pattern to allow for enhanced oil recovery by miscible gas drive. The target rates were 5400 barrels of oil (860 kilolitres) per day with 13 million ft3 (0.37 million m3) per day of associated gas and 70 million ft3 (2 million m') per day of wet, non-associated gas. Evaluation of early production tests showed rapid decline. The 100 ft (30 m) thick, low-permeability Tirrawarra oil reservoir was interpreted as an ideal reservoir for fracture treatment and as a result all oil wells have been successfully stimulated, with significant improvement in well production rates.The oil is highly volatile but miscibility with carbon dioxide has been proven possible by laboratory tests, even though the reservoir temperature is 285°F (140°C). Pilot gas injection will assess the feasibility of a larger-scale field-wide pressure maintenance scheme using miscible gas. Riot gas injection wells will use Tirrawarra Field Patchawarra Formation separator gas to defer higher infrastructure costs associated with the alternative option of piping carbon dioxide from Moomba, the nearest source.

The oil rim reserves development suggests complexity in maintaining the balance of gas and oil withdrawals from the reservoir, choosing the optimal well design and geosteering, justifying well operation conditions, etc. In addition, gas and oil reservoir can be complicated by diagenetic alterations of deposits, blocked structure, abnormal thermobaric conditions. The paper presents the results of conceptual approach to the Botuobinskiy horizon’s oil rim development design at the Chayandinskoye oil and gas condensate field with the presence of the above complications. This experience can be applied to assess the majority of fields in Eastern Siberia.

The Marcellus Shale is one of the largest natural gas fields in the world and has been the site of a massive natural gas development effort involving hundreds of oil and gas companies. With the onslaught of the “shale revolution,” developers moved into states like Pennsylvania and began drilling/completing natural gas wells by the hundreds. This development occurred so rapidly that attention to issues such as wellbore natural gas intrusion was not initially given the priority it demanded in all cases. This led to instances of alleged natural gas migration and impacts to groundwater supplies in several areas of the region. Although there has been an onslaught ofevaluations geared toward the study of groundwater contamination, the author has researched the natural gaswells themselves. Based on thousands of wellbore integrity studies in the Marcellus and other worldwide shale regions, this paper will summarize the forensic processes, analysis methods, and approaches used in assessing wellbore integrity as part of a natural gas migration investigation. The paper will also present details that pertain to remedial alternatives and approaches to wells requiring attention.

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.

Subject. This article explores the market valuation ratios of the twenty five leading public oil and gas companies between 2006 and 2018. Objectives. The article aims to identify key trends in the changes in market valuations of the largest public oil and gas companies, and identify the factors that have caused these changes. Methods. For the study, I used comparative, and financial and economic analyses, and generalization of materials of the companies' consolidated financial statements. Results. The article shows certain changes in the main indicators of market valuation of the leading public oil and gas companies and identifies the main factors that contributed to these changes. It establishes that the most significant for comparison and valuation are ratios based on balance sheet values of assets and equity, and EBITDA, DACF and net income ratios are appropriate as auxiliary ratios. The article says that the exchange segment of the industry has increased the debt load, so instead of market capitalization as a component of the coefficients of this group, it is advisable to apply the company's value indicator. Conclusions and Relevance. The article concludes that the market sentiments towards the stock market segment of the global oil and gas industry are getting impaired. This is quite natural against the background of falling profitability of most leading companies. The results of the study can be useful in evaluating, forecasting and developing measures to increase the market capitalization and value of public oil and gas companies.
