On 29 January, during the drilling of the Shakhrinav-1P exploratory well at the Sarikamysh licensed field in Tajikistan to a 5,563-metre bottomhole, the strengthening of the well using a 117.8mm-diameter production string was completed.
All technological operations were executed without any failures, strictly in accordance with the work plan. This means that the degree of completion of the well, whose construction has been on-going since December 2010, currently stands at more than 90%.
After the cement hardens, routine geophysical work will be carried out in the string and the deepening of the well will continue under the next section. Upon reaching the planned depth and whilst strengthening using the aforementioned string (production liner), procedures for testing the prospective objects identified will be carried out in the well.
Cooperation between Gazprom and the Republic of Tajikistan has been built on an Agreement on the general principles of conducting geological study of the subsoil in prospective fields since 2008. Gazprom has two licences for the exploration of prospective sections of the subsoil in Tajikistan (the Sarikamysh and West Shokhambari fields).
The planned depth of the Shakhrinav-1P well in the Sarikamysh field is 6,300 metres. It will be the deepest well ever drilled in Central Asia.
Preliminary estimates at Sarikamysh indicate that there are
18 billion cubic metres of anticipated gas resources. Expected oil reserves are 17 million tonnes, with 2 billion cubic metres of solute gas.
