RussNeft continues to develop Shapshinskoe group of fields /Khanty-Mansiysk Autonomous District, Western Siberia/ implementing ambitious drilling programs, ramping up production, and putting into operation new oilfields of this license area.
In May 2009 Sredne-Shapshinskoe oilfield has been put into operation. In the end of 2008 Verkhne-Shapshinskoe oilfield was put into test operation. Earlier in 2006 there was started operation and maintenance phase at Nizhne-Shapshinskoe oilfield. The remaining recoverable reserves of these oilfields exceed 80 million tons of oil.
The execution of this project is of strategic importance for OJSC Oil and Gas Company "RussNeft". In 2004-2005 the Company has created the basic engineering infrastructure of these oilfields, has built the most important production and administrative-social facilities and has prepared the group for the staged commissioning, which began in 2006 with the industrial operation of Nizhne-Shapshinskoe oilfield. Shapshinskoe froup of fields is being developed by the subsidiary enterprise of the Company – "NAK "Aki-Otyr".
The enterprise actively carries out works on exploitation drilling. For the year the operating well stock increased by 2 times and made 76 wells. Only in the beginning of 2009 there were constructed 20 new /in 2008 for the same period there were put into operation 5 wells /. Four of them have horizontal bored sections. The daily production rate of horizontal wells makes 88 per day, vertical – 40 per day. By the end of 2009 it's planned to put into operation 35 new wells.
The significant growth of oil production at Shapshinskoe group of fields depends on the commissioning of new wells. For five months of 2009 the oil workers of the enterprise have produced more than 343 thousand tons of oil, which is by 2,6 times more than for the same period last year. The level of daily output in Shapshinskoe oilfields in June 2009 was very close to 3 thousand tons.
Implementation of program on geological and engineering operations also made for the growth of oil output. In 2008 in the fields of the enterprise there were conducted 3 hydraulic fracturing operations with efficiency of 25 tons per day in the wells of the carry-over assets.
In 2008 at Sredne-Shapshinskoe oilfield there were conducted seismic exploration operations. There was explored the area of 191 square kilometers. This year exploration works are carried out at Verkhne-Shapshinskoe oilfield, in which there were explored 105 square kilometers of the territory.
Large-scale engineering operatins, creation of interfield production infrastructure of the enterprise, which are today carried out by Oil and Gas Company "RussNeft" in respect of Shapshinskoe group of fields, allow "Aki-Otyr" in the nearest future to exceed oil output by 1,5 million tons.
