Recoverable С1+С2 reserves at Afanasyev field were estimated at 3.8 mln. tons (including С1 – 0.6 mln. tons, С2 – 3.2 mln. tons), JSOC Bashneft informs. Recoverable reserves, approved by the State Reserves Committee, were estimated following the testing of two prospecting holes.

In December 2008 Bashneft won the tender for Khasanovskoye area located in Bakalinsky region in the western part of Bashkortostan. The area shares a border with Kalayevskoye, Mustafinskoye and Ardatovskoye oil fields already developed by Bashneft.

2D seismic survey found two promising structures, namely Zarechnaya and Ikskaya. In 2012 Bashneft completed drilling at two exploration wells of these deposits. Currently both wells produce nearly 80 tons per day as part of the production testing and have a strong potential for oil production growth.

In 2013 Bashneft will carry out 3D seismic survey in the territory of Khasanovskoye area in order to clarify Afanasyev field limits. The drilling of a new exploration hole will be completed. It is also expected to drill four horizontal wells as part of the test production project the same year.

According to the Bashneft Vice President for Geology and Development Yuri Krasnevsky the success of Khasanovskoye area convincingly shows good prospects of further exploration activities in the territory of Bashkortostan.

“Although the previous four exploration wells were a failure, the Company specialists penetrated the reservoir with unique permeability at the first try based on the comprehensive 2D seismic analysis and stratigraphic drilling for the upper part of the profile», Yuri Krasnevsky says.
