Specialists of the company “RN-Purneftegaz” started industrial exploitation of Achimov deposits. Development is conducted in Tarasovskoye field in Yamal-Nenets Autonomous Okrug, the initial geological reserves on category АВ1+В2 are estimated in 47 million 800 thousand tonnes of oil. In the coming years in the field it is planned to drill 66 extraction wells on 7 cluster sites.
5 oil wells with the production rate exceeding the expected indexes have been input to operation since the beginning of pilot development of Achimov deposits in 2017 in Tarasovskoye field. Thus, the amount of extraction in one well made 213 tonnes of oil per day instead of the planned 105 tonnes, as the office of information policy of “Rosneft” informs.
The reserves of oil in Achimov layers at the depth about 3-3.5 thousand meters are referred to the category of hard-to-recover. Extraction is complicated with geological heterogeneity of layers, as well as low permeability of oil-bearing rock. The technology of multi-stage hydraulic fracturing is used for effective extraction of reserves with difficult geological structure. The project of extraction of difficult reserves of Achimov deposits was prepared within joint work of geologists of “RN-Purneftegaz” and specialists of “BashNIPIneft”.
The company “RN-Purneftegaz” is one of the basic centers of oil and gas extraction of the oil company “Rosneft”. The enterprise is situated in the town Gubkinskiy and fulfills production activity on 13 license areas. During development of fields “RN-Purneftegaz” extracted more than 260 million tonnes of oil and gas condensate, more than 110 milliard cubic meters of gas.
