Gazprom International has successfully completed a staggered programme of geological research works in the Ustyurt Region of Uzbekistan.
The five year programme, embarked on in 2006, contained three stages. The first two involved geological and geophysical exploration and drilling of search and exploratory wells. As a result of the third and concluding phase, carried out during 2009-2011, the Djel gas condensate deposit was opened in the Shakhpakhty Investment Area (Karakalpakstan).
Realisation of this programme involved a full-scale range of 2D seismic exploration works over 7,700 linear kilometres and 3D works over 600 km2; interpretation of the seismic data, aeromagnetic photographing and gravimetric examination of 300 km2 was followed by drilling of 20 exploratory wells in 7 investment areas.
“The geological exploration works in the investment areas were carried out with full respect for the programme and for all ecological standards”, stated Maksug Anderjanov, Gazprom International’s representative in Uzbekistan, emphasising that Gazprom International currently occupies the leading position amongst foreign companies working in Uzbekistan, in terms of volume and rate of works done.
OAO Gazprom’s joint work with Uzbekistan is built on the basis of a 2006 agreement on principles of geological study of underground resources in the investment areas in the Ustyurt Region. This agreement provides for provision to Gazprom of an exclusive right to subsequent development of new hydrocarbon deposits under conditions of a production sharing agreement (PSA).
The company is currently preparing a report calculating the natural gas and gas condensate reserves in the Djel deposit and its subsequent defence before the State Committee for Reserves in the Uzbek Cabinet of Ministers.
The Djel Deposit is located 235 km from the Central Asian Main Gas Pipeline (Centr). Since the programme began in December 2006, over $400 million has been invested in geological exploration in the Ustyurt Region of Uzbekistan.
Together with the geological exploration works programme, Gazprom International has, under the conditions of the PSA, been further developing the Shakhpakhty Deposit in Karakalpakstan.
