Gazprom International, PJSC Gazprom’s sole operator of hydrocarbon prospecting and exploration projects abroad, together with Petrovietnam, Vietnam Oil and Gas Group, have completed a five-year drilling programme at Blocks 05-2 and 05-3 on the continental shelf of Vietnam. The project results were reviewed by the members on 22 and 23 December in Vietnam at a geotechnical meeting organized by Bien Dong POC, a branch of Petrovietnam.
The meeting was attended by managers and specialists from the companies involved in the project, as well as representatives of the Vietnamese Ministry of Industry and Trade and of Petrovietnam Drilling, the key drilling contractor.
The parties highlighted that a total of 16 production wells have been drilled in accordance with the development plan of the Hai Thach and Moc Tinh fields located within Blocks 05-2 and 05-3. Nine of them have been constructed in the Hai Thach field and seven are situated at the Moc Tinh field. The depth of the wells is at approximately 5,000 metres.
During the meeting, the Russian and Vietnamese specialists stressed that there had been no incidents leading to occupational injuries during the drilling works. All of the activities were carried out in strict compliance with Vietnamese legislation and international regulations.
Gas production at the Hai Thach and Moc Tinh fields started in 2013. Last December, the partners fulfilled the 2016 natural gas production plan for the contract blocks ahead of schedule, exceeding the rate of 2 billion cubic metres. The total accumulated hydrocarbon crude production at the blocks has reached nearly 6 billion cubic metres.
Blocks 05-2 and 05-3 are situated in the Nam Con Son oil and gas basin in the southwest of the South China Sea. Two gas condensate fields, Moc Tinh and Hai Thach, have been discovered within their territories. The development project for these fields has been implemented under production sharing agreements for Blocks 05-2 and 05-3. Gazprom International entered into these agreements in July 2013 on the basis of a share transfer agreement for PSAs signed with Petrovietnam the previous year.
Gazprom International holds a 49% share in the project, while Petrovietnam holds 51%.
The projected annual gas production rate was 2 billion cubic metres and this figure was reached in 2016. All the gas produced under the project is supplied to the coastal Phu My distribution centre via the Nam Con Son-1 gas transport pipeline.
