The Russian closed joint-stock company, Gazprom zarubezhneftegaz, has begun large-scale mobilisation work in the Sarikamish prospecting field in the Shakhrinavsky district of Republic of Tajikistan.
The head of the company’s branch in RT, Sergei Tumanov, informed journalists that at the beginning of April, representatives of the Saratovneftegeophysika contract company, which will lead the geophysical work, visited the Sarikamish site and studied ways of delivering the hardware needed, as well as defining the area to be occupied by the camp where specalist and technical personnel will be centred. According to him, the site has already been selected and agreed by the local authorities.
“Company experts have identified routes for delivering equipment, as there are practically no roads in the area, but plenty equipment. The seismic group intend to take around 35-40 platforms and associated equipment. At this moment, 15 are already in transit, five will be there either today or tomorrow, and the rest will arrive around 10th May", he remarked. “As expected, towards the end of May, the camp will by then be fitted out, and equipment delivered, so the surveyors can begin their work, and then the seismographers - so we are aiming for success by June.”
Meanwhile, according to Mr. Tumanov, before starting field work the company will sign a subsoil use contract with the Tadjikistan government, which is the main document determining the basis for taxation and a number of other organisational points.
Speaking about the work carried out in the Sargazon prospect, the company representative mentioned that the work was conducted according to a standard two-dimensional seismic profiling method, though during the work the method was considerably strengthened, so that fairly good results were given. “The results of the study gave very interesting new information about the deep-deposited beds which are the most promising”, emphasised Igor Shatalov, the deputy director for production. “This work showed that the architecture does not exist as it was when drawn before. Many local experts urged that immediate deep drilling be carried out. Gazprom did not go along with this, and decided to inspect whether it was present by exploration and were right to do so. If we had sunk a well (assuming a depth of 6 kilometres, the cost of which would be around $50 million), then money would have been spent for no reason”.
According to him, the 2D seismic profiling method allows features of interest requiring further exploration to be singled out, and this method is the one which will be implemented.
In addition, research has shown that in order to study the area it is necessary to proceed to the most complex method – 3D. “This method has not been used yet in Tajikistan, because of its complexity and high cost.
“As a rule, the area-based method (3D) is used on sites where prospect drilling has already obtained inflows of oil or gas. 3D is used for more accurate definition of the structure of deposits, so that afterwards, based on this survey, the network of exploratory wells can be located correctly”, he noted. “We took a different path, decided to take the lead for a little while and are already at the exploration stage of sinking a deep well, to provide a 3D seismic exploration profile at our own risk. We are confident that the data we get will help us to site an exploratory well accurately, in order to obtain inflows of hydrocarbons.”
The company representative also mentioned that the work which had been carried out in Sargazon went to the leading schedule - that is, even before an agreement was signed regarding the general principles for conducting a geological study of the subsoil for oil- and gas-rich areas in Tajikistan - which is an unprecedented occurrence for Gazprom.
OAO Gazprom (joint-stock company) is the largest gas company in the world. Its main areas of activity are the geological exploration, extraction, transportation, storage, processing and production of gas and other hydrocarbons.
The closed joint-stock company Gazprom zarubezhneftegas was established in 1998. The company is an operator for Gazprom for the exploration and development of hydrocarbon deposits and the construction of facilities for the oil and gas industry abroad, principally in Middle and Near East countries, South-East Asia and Afrika, but also in CIS (Commonwealth of Independent States) countries. From January 2007 the company has been wholly-owned by the public limited company Gazprom.
Currently Gazprom zarubezhneftegaz is successfully implementing a number of overseas projects on Gazprom’s behalf, particularly in Uzbekistan, Kyrgyzstan, Tadjikistan, Vietnam, India and other countries.
