The article reveals the effect of new oil and natural gas classification establishment, which came into force on January 1st, 2016, as well as its positive and negative aspects. The classification is adjusted to the international standards of Society of Petroleum Engineers (SPE) and the USA Security and Exchange Commission (SEC). Its basic feature is the priority of economic efficiency. The practical value lies in the provision of state interests at reserves cost evaluation, which builds the major part of national wealth, as well as in the consideration of tax incentives eligibility. Introduction of such classification should result in the increase of Russian deposits investment potential as well as in the economic efficiency of hydrocarbon reserves production under the conditions of qualitative and quantitative mineral-resource base characteristics deterioration. However, the geological (reservoir type, reserve calculation algorithm, degree of reservoir structure complexity, reserves division), technological (well spacing, oil recovery factor), organizational (computer modeling) and administrative (schedule reduction and special technical and economic features of project approval) aspects could negatively reflect on small subsurface users developing one or several small and middle-sized deposits. Considering the reviewed issues, the author suggests the additional correction of legal and regulatory framework with the aim to eliminate the abovementioned consequences and to support the financial position of small subsurface users.
PROMISING PERSPECTIVES OF OIL RE-EXPLORATION IN PALEOCENE SEDIMENTS OF BLAGODARNENSKAYA STRUCTURE IN STAVROPOL REGION
Stavropol Region is one of the oldest petroleum producing regions of the country. To date, much of its fields are depleted and prospects for the discovery of large hydrocarbon deposits have been exhausted. At the same time, there is still the possibility of opening small and medium-sized deposits localized in the source rock formations.
In the middle of the last century, similar deposits have been identified within Prikumsk-Tyulenevskiy (Praskoveyskoe, Achikulakskoye, Ozek-Suat and a number of other fields) and Chernolesskiy (Zhuravskoye, Vorobyevskoye) tectonic elements. However, these findings were largely spontaneous due to lack of approved and unified approach to the petrophysical evaluation of dedicated reservoirs from well logs. At the same time the experience of shale reservoirs studies, as well as the results of its implementation to evaluation of deposits of Zhuravsky-Vorobyevsky petroleum accumulation zone, allows to revise existing well log materials for deep wells of explorational and depleted structures, and to identify promising intervals for further re-exploration and testing.
In this work, Paleocene sediments of Blagodarnenskaya explorational structure of the Stavropol Region were studied. Despite the approval of the oil bearing of these deposits within the Prikumsk-Tyulenevskiy tectonic element and the positive signs of hydrocarbon saturation from initial well logs data, its evaluation and testing within Blagodarnenskaya structure dedicated to the North-Stavropol tectonic element, were not conducted. However, the results of well logs analysis performed by us with the use of interpretation technique approved on shale reservoirs of Zhuravsky-Vorobyevsky petroleum accumulation zone, as well as the core tests indicate the presence of oil-saturated reservoirs in the Paleocene sediments of Blagodarnenskaya structure.
The sum of the obtained results and confirmation of the oil saturation of Paleocene sediments on the other structures allows us to propose promising perspectives of re-exploration of the Paleocene deposits within Blagodarnenskaya structure. The presence of a large number of abandoned deep exploration wells suitable for the re-entry allows performing re-exploration by means of the existing wells fund without drilling a new one, what would significantly reduce costs and ensure the profitability of the operation in the event of success.
The purpose of the article – state analysis, trends and prospects of development of the global hydrocarbon market. In particular, detailed analysis of the market categories such as supply and demand was made. Factors of demand for oil and natural gas, the major regions of consumption of hydrocarbons, the market structure of oil and natural gas consumption of the countries are represented. It was revealed that the growth in demand for energy resources was caused by increased motorization of individual countries (especially India and China). The major share of oil and natural gas demand at the regional level provide the Asia-Pacific region and North America, at the country level – United States (US) and China. The largest oil producer at the regional level is the Middle East, at the country level – Saudi Arabia, the United States and the Russian Federation. Saudi Arabia and the Russian Federation provide the maximum export oil supplies. The main flows of oil imports are sending to the United States, China, India and Japan. The Russian Federation leads the global natural gas market the largest proven natural gas reserves belong to Russia. The country provides the maximum export pipeline natural gas. The largest import purchases of natural gas occur in Germany, USA, Italy and Turkey. The authors calculated the figure availability of natural gas reserves of countries. Security of the Russian Federation in 2015 was 56 years. To actively growing market for liquefied natural gas is analyzed. LNG shipments rose by almost half over the past decade. The factors for expansion of markets for LNG sales are shown.
Evaluating the effectiveness of implementing a program in any of the company is the initial stage of its implementation. Therefore, for accurate results, it is important to assess the effectiveness, taking into account all the factors affecting it. In the oil and gas companies, large-scale projects, usually affecting both the internal and the external environment. Therefore, the industry is very important to carry out an accurate assessment of program effectiveness. To this end, it is important for each program to determine and take into account the existing risks in it.
In this paper we consider the program of pipeline transport of oil and oil products. Analyzing the main activities of the industry, four types of programs aggregated groups were identified that can be implemented in oil and petroleum products transportation industry. Accordingly, these programs have distinctive characteristics, which do not allow the use of any method of accounting and risk assessment. Therefore, on the basis of the existing features of the software company’s oil pipeline transport in the isolated methods of accounting and risk assessment, which are suitable for each type of consolidated programs. These methods can be used in the evaluation of the program, but with respect to the study branch these methods do not allow to allocate certain types of risks. These methods can calculate the quantitative value of the onset of the possible risk, taking into account only the general types of risk events. The individual and specific risks remain without attention and consideration.
