On Ashalchinskoye viscous oil (EVO or natural bitumen) of "Tatneft" achieved an average production rate per well over 52 tons per day, the press service of the company.
Trial operation of oil and gas deposits is controlled "Nurlatneft" since 2006. In developing the technology used steam assisted gravity effects through paired horizontal wells (through one of them steam is injected through the other — pumped oil). At present, 11 pairs of drilled wells, 7 of them in operation. 8-th pair is scheduled to work at the end of March this year.
In order to develop and steam injection into the reservoir was built boiler domestic production (Biysk) capacity of 50 tons of steam per hour. For steam injection at 9 injection wells are currently used capacity of one boiler. At night, he produces about 550 tons of steam. Bring the work of the boiler at full capacity is planned in August this year as the commissioning of new wells.
Development project is developed with the support of EHV government agencies, research organizations, and the Republic of Tatarstan, Russia. In the development and implementation of new technologies, equipment and methods of work involved specialists and workers NGDU "Nurlatneft" TatNIPIneft and service companies.
Recall that in 2011 "Tatneft" on Ashalchinskoye natural bitumen from 7 pairs of wells produced 41.5 million tons of oil. In January of this year, the maximum production rate of one pair of 44 tons per day.
This type of hydrocarbon is considered one of the alternatives against the depletion of conventional oil. And in Tatarstan, where resources SVN can reach 7 billion tons, even thought that its development could be a new strategic direction for the country’s oil industry.
Natural bitumen — a semi-solid or solid mixture predominantly hydrocarbon composition, soluble in organic solvents. Genetically, they are, to varying degrees degassed, lost light ends, viscous semi-natural oil derivatives — Malta, asphalt, asphaltites.
Natural bitumen — it is an integral part of the fossil fuels. These include natural oil derivatives resulting from the violation of conservation of its deposits as a result of chemical and biochemical oxidation, eg asphalt, kerites, Malta, etc. ozokerites extraction is carried out mainly quarry or mining method.
Traditional bitumen used less frequently, but produced on the basis of their bitumen-polymer materials and synthetic oil are very popular. It symbolizes a new era in the development of the market of bitumen. The largest reserves of bitumen are in Canada. In recent years a steadily rising rates of bitumen production at its base synthetic oil.
Despite new developments which occur only while in Canada, mainly used in the construction of bitumen, in particular for the production of roofing materials. In the former USSR identified about 700 deposits of bituminous rocks, mainly in Russia, Kazakhstan and Azerbaijan. In the Russian natural bitumen resources according to various estimates range from 30 to 75 billion tons. In the United States produces about 28 million tons of bitumen, of which about 10 million-modified.
