Gazprom International has begun testing at a second exploratory well, drilled in the Kumoy prospective field on the Ustyurt plateau in the Republic of Uzbekistan.
The Kumoy-2 well, with a depth of 4,170 metres, has revealed six productive horizons, which are also due to be tested. The first assessments of the prospects for gas content at this field will be made following this work, which is expected to be completed by the end of the year. According to preliminary data, the productive objects contain high-quality methane gas with extremely low hydrogen sulphide and carbon dioxide content.
The Kumoy field is located within the boundaries of Gazprom International’s Shakhpakhtin investment block, 25 km from the Dzhel deposit, which was opened here in 2009 and whose anticipated resources amount to approximately 6 billion cubic metres of gas, and more than 40,000 tonnes of gas condensate. A full geological exploration complex has been built on the Shakhpakhti block under a five-year programme of geological surveying, the completion of which was announced by Gazprom International at the start of this year. Work is currently being carried out according to calculations of reserves at the deposit to be put forward to the State Commission for Reserves under the Cabinet of Ministers of Uzbekistan.
Gazprom’s collaboration with the Republic of Uzbekistan is built on an Agreement regarding the principles of conducting geological surveying of the subsoil in the investment blocks of the Ustyurt region from 2006. The agreement provides for granting Gazprom the exclusive right to future development of new hydrocarbon deposits under the terms of a Production Sharing Agreement (PSA). The Dzhel deposit is located 235 km from the main Central Asia – Centre gas pipeline. Around US$400 million have been invested since the start of the programme (December 2006) in exploration in the Ustyurt region of Uzbekistan.
Concurrently with the exploration programme, Gazprom has been constructing facilities and undertaking development at the Shakhpakhti deposit on Kara-Kalpak territory.
