Vostochny Makarovskoye gas-condensate field
The Vostochny-Makarovskoye Licence Area encloses the producing Vostochny Makarovskoye gas and condensate field. The Vostochny-Makarovskoye field was discovered in 1989 by a LUKoil Group entity. The licence was acquired at a government auction in 2006 by the Volga gas subsidiary, GNS.
Gas produced at the Vostochny Makarovskoye field is transported by intra-field flow lines to the Group’s gas processing facility located at the Dobrinskoye field site at a distance of approximately 5 km.
GNS has access to the regional pipeline system via a common connection with the Dobrinskoye field through the Korobkovsky-Zhirnovsk gas pipeline, which connects to a Gazprom terminal in the city of Zhirnovsk.
After undertaking the required modifications to the Dobrinskoye gas plant, the first two production wells, drilled by Volga Gas during 2008, were connected to the plant and commenced commercial production in October 2012.
Shortly after purchasing the licence, Volga Gas acquired 20 km2of 3-D seismic to define the drilling programme which commenced in September 2007. The first well, VM#1 successfully tested commercial rates of gas and condensate. This was followed by further wells:
- VM#2 was successfully completed and tested in 2008.
- VM#4 encountered a relatively small productive pay-zone and will in the near future be deviated to a more promising zone for production.
- Well #30 (designated Dobrinskoye #30, although it is actually drilled on the VM field), drilled by a previous licensee, was re-entered during 2012 and successfully recompleted as a third production well.
From 2010 to 2012, the company carried out extended test production on wells VM#1 and VM#2. Following the completion of the preliminary stages of the upgrade to the Dobrinskoye gas processing plant, production commenced from the two initial wells.
During the first half of 2013, a successful workover on the VM#1 production well more than doubled that well's estimated daily productive capacity to 300,000 cubic metres of gas and over 600 barrels of condensate, a total of more than 2,700 barrels of oil equivalent per day.
As the plant capacity expands on completion of the upgrade project, further development drilling on the VM field will be undertaken between 2015 and 2016 including a sidetrack of well VM#4 and two new wells on locations identified as VM#3 and VM#5.
