A complex gas
The Gas Field Division of the Association deals with production, treatment and also delivery of gas condensate to the processing facilities. The personnel of this division provide service to 15 complex treatment plants for Senomanian gas and 4 plants for Valanzhinian gas as well as to 26 booster compressor stations and 4 gascooling stations. Gas and condensate are recovered from the Valanzhinian and Senomanian reservoirs by more than 2000 development wells.
The Senomanian is the pure gas
reservoir (almost pure methane). Gas dehydration and treating is carried out at a complex gas treatment plant with diethylene glycol used as an absorbent. The total annual output of absorption gas dryers is 15-20 billion cubic meters. Gas from Valanzhinian reservoirs differs from the Senomanian gas by high content of heavy hydrocarbons (ethane, propane, butane and etc.). The Valanzhinian gas is treated in low-temperature separators at 4 complex gas treatment plants.
The products of these plants are dried gas and unstable gas condensate.
The Division of Oil Recovery Enhancement and Well Repair provides efficient operation of the wells. The Division performs more than a hundred repairs and prevents shutdown of up to 40 wells annually.
To stabilise the volume of gas production, the program of development of new fields and prospects of gas production from the developed reservoirs for the period of 1998 to 2015 were adopted in the Association, It is planned to put on production Senomanian gas reservoirs of Tab-Yakhinskoye area (the Pestsovoye field) and expand the drainage area of Yen-Yakhinskoye by drilling additional development wells.
In Apill 1978, the fil-st complex gas
treatment plant was commissioned
tit the Urengoi field.
