The joint operating company Vietgazprom is preparing to carry out tests on the VGP-113-BV-3X exploratory well in the Bao Vang structure (in the central part of the continental shelf of the Socialist Republic of Vietnam).
The well was drilled to a depth of 1,600m in August this year. The four prospective objects were selected for testing according to core sampling results and based on GIS data interpretation results.
The drilling of the VGP-113-BV-3X exploratory well is being carried out by the Joint Operating Company Vietgazprom within the scope of fulfilling the Oil-and-Gas Contract for block 112, signed on 11.09.2000.
The contract provides for the drilling of three prospecting holes and three exploratory wells. The first well was drilled by the joint operating company in the Bach Chu structure in 2004. As a result of the drillhole survey, it was proposed that the Contract's area of application be widened to include the adjacent block number 113.
The second prospecting hole (VGP-113-BD-1X) was drilled by Vietgazprom in June 2007.
Three wells in the Bao Vang structure, drilled by Vietgazprom in August 2007, indicated recoverable reserves of gas.
According to this survey, inflows of gas amounted to around 400,000 cubic metres per day. There is also gas condensate present in the well's production.
Because the boundaries of the open Bao Vang deposit exceed the limits of block 113, in 2008 the Vietnam government licensed the expansion of the Contract's area to block 111/04, where after a while Vietgazprom drilled the VGP-111-BV-2X exploratory well.
Continuing its work in the blocks, in 2009 Vietgazprom drilled prospecting holes in the Pribrezhny structure and the Bao Chang structure.
Subsequently another prospecting hole (VGP-113-BD-2X) was drilled in the Bao Den structure. According to the survey of this hole, it became possible to confirm the opening of a second gas condensate deposit with an overall gas yield of 300,000 cubic metres per day and condensate yield of 3.75 cubic metres per day.
