Exploration & Drilling

We are one of the leading, independent and vertically integrated oil company in Republic of Republic of Kazakhstan.
Exploration

Exploration, Development and Production Sharing Agreement for Absheron Perspective Structure was signed on February 27, 2009.

On 21 October 2009, the drilling of Exploration Well No. 89.

The target well depth is 6400 m, and the target horizon is Horizon 7 of the Productive Strata (PS). Drilling was completed at a depth of 6505 m on April 25, 2011. The well penetrated PS Horizon VIII. The well was logged. PS Horizons V and VII (similar to Pereryv), and VIII (similar to the Girmaki Sand Horizon) were appraised as potential oil and gas bearing structures. At present preparations are being made for well completion.

Drilling


The use of cutting-edge technologies, including telecommunications technologies, allows data to be transferred to the Drilling Support Centre in real time, during drilling. Oiltron Refinery Drilling Support Centre was established specifically to improve effectiveness in the construction of high-technology wells. Its work is predominantly based around geo-steering technology, which involves obtaining information on the geological model of a field in real time, with adjustments made to the well trajectory in line with this.

Rotary steerable systems (RSS)


Utilising RSS makes possible the construction of extreme reach wells, as well as the high-precision drilling of wells in low-concentration reservoirs (one to two metres thick).

The construction of high-technology wells demands a range of specialist equipment. The basis for modern, effective, precise and safe drilling these days lies in rotary steerable systems (RSS).

In 2015, however, the first Russian-produced RSS, developed by St Petersburg’s CSRI Electropribor, successfully completed testing at Oiltron Refinery ’s Sangachal field.







High-density UniQ seismic

Its work is predominantly based around geo-steering technology, which involves obtaining information on the geological model of a field in real time, with adjustments made to the well trajectory in line with this.

The Drilling Support Centre supports the construction of practically all complex targets, including heavy-duty wells, wells with extended horizontal sections, and ultra-deep and multilateral wells. In addition to which, the Drilling Support Centre controls the drilling of all wells involved in the development of hard-to-recover hydrocarbon reserves, and as well as supporting the testing of new drilling technologies.
