An important aspect of the analysis of accident risks at gas transport system facilities is the determination of damage areas where recipients are injured by shatters, excessive pressure of the first and second waves, pressure blast effect and fire radiation. From the above-mentioned adverse factors a special role, by virtue of its specific nature (inevitability and transiency), is assigned to a fragmentation and gasdynamic (a shock wave one from the first wave and a blast one from the high-speed gas jet) effect. The above-mentioned effects, which are realized at the initial stage of any accident, act as the main adverse factors in accidents without inflammation. The article presents the main provisions of newly developed methodological approaches to the assessment of possibilities of fragmentation and gasdynamic effects in accidents at hazardous production facilities of gas main pipelines. Analytical design ratios are presented to establish the sizes of damage areas. It is shown that when pipelines are depressurized, the sizes of human lethal areas (from an impulse action of the jet) are significantly larger than the ones from a shock wave effect.

Keywords: EFFECT OF ADVERSE FACTORS, ACCIDENT WITHOUT GAS INFLAMMATION, GAS MAIN PIPELINE.

» Review of process solutions on the development of turonian low-permeability gas deposits

Large Cenomanian deposits, which are traditional for Western Siberia, especially in the regions with a well-developed infrastructure, have been in operation for a long period of time and have been providing the main volume of produced gas up to the present day. However, the reserves of such deposits run dry and the gas output decreases over time, and therefore the production stimulation of hard-to-recover gas reserves takes on greater importance, including at remote fields with complex climatic and natural conditions. At the same time, the development of Turonian deposits is much easier and profitable than the development of shale since the prime cost of shale gas is a sequence higher than the prime cost of Turonian gas. However the level of complexity and investment of Turonian gas production is certainly higher in comparison with similar characteristics of Cenomanian gas. It makes the most sense to start developing Turonian deposits as part of the existing extraction facilities and to use the existing field infrastructure for that. When analyzing the experience of studying and developing Turonian gas deposits, one identified some difficulties that emerge in the course of development and that call on scientists and practitioners to accelerate efforts aimed at searching and implementing production stimulation means at fields with hard-to-recover reserves. The article contains an analysis of the results of the development of Turonian low-permeability gas deposits of different subsoil users in the territory of the Russian Federation. The emphasis is placed upon technical and process solutions used by different companies and upon the assessment of process efficiency following the results of gas-dynamics research (GDS) interpretation. A comparison is drawn between the results of GDA interpretation of wells with a similar pumping type for the Kharampur Gas Field and the Yuzhno-Russkoye Field.
