The production of natural gas at the Shakhpakhty field, a development and reconstruction project that Gazprom International has been working on since 2004, has reached 300 million cubic metres this year, which is approximately 20 million cubic metres higher than the projected level.
At present, roughly 280 million cubic metres of gas have already been recovered at the deposit in northwestern Uzbekistan, and compared with last year's indicators, extraction at Shakhpakhty has demonstrated growth of almost 40%.
During 2012, Gazprom International specialists performed capital renovation and started up five new wells. There are now 16 production wells at the deposit, and average daily gas production is 956,000 cubic metres. According to the project, a total of 19 wells must be recovered.
The total produced gas volume at Shakhpakhty since 2004 has reached 2.1 billion cubic metres.
Shakhpakhty is a gas condensate field located in Uzbekistan in the southeastern part of the Ustyurt Plateau within the Kungradsky Region of the Republic of Karakalpakstan, and was discovered in 1962. Geological surveys carried out here before 1968 confirmed initial commercial gas reserves in the amount of 46.5 billion cubic metres. Commercial production began at Shakhpakhty in 1974, comprising 2.5 billion cubic metres per year. In 1983, the Shakhpakhty booster compressor station began operation, but was stopped in February 2002 due to inadequate power for the required upstream gas supply pressure. At that time, the operating organisation decided to shut down production and the wells were preserved. During the production period, 36.5 billion cubic metres of gas were produced from the deposit, which is approximately 78.5% of the initially confirmed reserves. At present, Shakhpakhty's extractable reserves are estimated at approximately 8 billion cubic metres.
The reconstruction and further development of Shakhpakhty is a pilot project of Gazprom International in the Republic of Uzbekistan carried out under a Production Sharing Agreement signed in 2004 for a period of 15 years. In 2004, LLC Operating Company Zarubezhneftegaz - GPD Central Asia was created to execute this project (It is now one of the operational structures within Gazprom International). Its goals and tasks are field surface construction and development, production and distribution of raw material, construction of the corresponding infrastructures, gas purification and storage, performing environmental protection measures, and other activity directly related to such work. Natural gas production from the field was renewed in August 2004; commercial inflow was obtained from 10 wells.
In 2006, the operating company completed reconstruction of the Shakhpakhty booster compressor station and set up preliminary gas treatment; a modern base camp was also built at the field. The gas produced at Shakhpakhty is delivered to the Karakalpaksky compressor station and then through the Central Asia-Centre gas pipeline to consumers.
As part of the license for developing four productive formations, work on the extraction of raw materials and capital renovation work in the wells has been carried out since 2004. In 2010 the operator received a license for developing three additional underlying productive formations.
