VINCA OIL FIELD Test site


The Bakhtinskaya Reservoir is located on the territory of the Ermekeyevsky and Bizhbulyaksky districts of Bashkortostan. In the west and southwest, the reservoir adjoins the Orenburg region. The subsoil user is VINKA JSC.The Bakhtinskaya Oil Reservoir was discovered in 1991 and put into trial operation in 1998. In 1995 (Protocol No. 1834 dt. 23.05.1995), for the first time, the oil reserves of the Bakhtinskaya Reservoir of the Znamensky Oil Field were registered in the State Reserve Register. In 2009, the reserves of the Bakhtinskaya Reservoir on productive formation members P 2, P 3, P 4 and P 5 were reviewed and approved by the State Commission for Reserves (GKZ) (Protocol No. 1870 of 06.03.2009). In 2010, based on the results of exploratory drilling and seismic exploration of the MOGT 2D, an operational calculation of oil and dissolved gas reserves was carried out for the reservoirs of formation members P 4 of the Kungurian, P 5 of the Artinskian and P 6 of the Sakmarian stages of the Bakhtinskaya Reservoir of the Znamenskoye Field (Rosnedra Protocol No. 18/400 of 07.07.2010). 

In 2018, an operational recalculation of reserves was carried out in order to bring the boundaries of the categories of reserves into compliance with the requirements of the Current Classification. 

The initial geological reserves of oil, which will be registered in the State Reserve Register on 01.01.2019, are: 

  • 9,117 thousand tons - category B 1;

  • 44,861 thousand tons - category B 2.
