This research is relevant as the development of world energy over the past decades is characterized by increased production and consumption of natural gas. One of the leading gas producing countries is Russia, which accounts for more than 25% of the world’s total gas production. In the Energy Program of the Russian Federation, by 2020, the planned volume of gas production will be 700 billion m3. The development strategy of the gas industry provides for the extraction of residual geological reserves. All these aspects are pushed to create new and effective technologies for gas preparation, as well as modernization of existing technological processes and equipment for gas preparation.
Every year, the role of gas in the global fuel and energy balance is becoming increasingly important. Thus, in 2002, global production amounted to approximately 2.800 billion m3. Of these, only 522 billion cubic meters of gas were produced by Russia’s Gazprom. The growth of gas production in Russia by 2005 was about 5%.
The state of the oil and gas industry is characterized by low automation, the use of obsolete and worn-out equipment, a decrease in gas production in exploited deposits, an ever-increasing remoteness of developing deposits, and so on. In conditions of increased competition from foreign producers, modernization of gas engineering and increasing the efficiency of gas production are vital for ensuring energy security and stable economic development of the country.
The article discusses the problem of exploitation of gas fields, at a late stage of development. The operation is complicated, because of the accumulation of condensation and formation water, a limited number of technological processes are used, as a result of which the productivity of the wells decreases or irreversible gas losses occur during process blowdowns.
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.
Optimization of geological and prospecting works for maintenance of oil recovery level by the example of Orenburg region
Considered State-of-the-art oil resource base the Orenburg region. Traced trends in oil production during the period 1996-2011, the growth stocks and filling, the effectiveness of geological exploration work and success looking for perspective objects. Identify areas for optimization of geological exploration work to maintain levels of oil production in Orenburg region.
The complex analysis of seismic data, core analysis, wireline logs information and well tests results has been made for identification of fracture zones within reservoir. Reservoir model has been justified and it allows to increase efficiency of development.
The analysis of the factors, influencing upon the efficiency of hydraulic fracturing on injection wells in Vostochno-Leninogorskaya field of oil-and-gas production department “Aznakayevskneft”
The efficiency of hydraulic fracturing according to the production rate and production performance of the neighboring recovery wells were assessed. The influence of such technological factors as breakdown pressure, perforated formation thickness, proppant volume, breakdown fluid volume was examined. Incremental oil production versus reservoir characteristics such as porosity, permeability, shaliness and oil saturation were analysed. Incremental oil production from respondent wells versus their distance to the nearest injection well fractured were studied.
