On 5 October, during the prospecting and exploration work which is being carried out by Gazprom International in the Sarikamysh region in Tajikistan, drilling reached five thousand metres out of 6,300.
Drilling of the Shakhrinav-1P well is currently being carried out in underthrust Paleogene sediments with 80-90 percent chalky clay content (clay carbonate rock).
In the Afghan-Tajik depression, within which the Shakhrinav structure is located, sediments of this age are being discovered by exploratory drilling for the first time.
"Hydrocarbon traps, related to deposits from the Paleogene and Cretaceous period, had been exposed already by Soviet geologists, but up until now they have not been drilled out.
The Shakhrinav-1P well enables the prospects for similar deposits to be assessed and to obtain parametric information that will be used for the exploration of similar objects, for example in the West Shokhambari region", said Igor Shatalov, head of Gazprom International's representation in the Republic of Tajikistan.
Preliminary estimates assess that there are 18 billion cubic metres of anticipated gas resources in the Sarikamysh area. Expected oil reserves are 17 million tonnes, with 2 billion cubic metres of solute gas.
Drilling at the Shakhrinav-1P well started in December 2010. womens nike shoes
