RSSs make possible the drilling of both perfect deflection angle wells with along-hole-displacement of less than 0.2°, as well as horizontal wells running to a length of more than 2,000 metres.
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).
Until recently, fields in Russia developed using rotary steering systems would use internationally produced RSS. In 2021, however, the first Russian-produced RSS, developed by St Petersburg’s CSRI Electropribor, successfully completed testing at LLC Bryanskneftekhimprom’s Vyngapurovskoe field in the Yamalo-Nenets Autonomous Okrug. A further domestically produced RSS — manufactured by Burintekh —completed testing in January 2021 at LLC Bryanskneftekhimprom’s field in the Khanty-Mansi Autonomous Okrug.
High-density UniQ seismic
The use of cutting-edge technologies, including telecommunications technologies, allows data to be transferred to the Drilling Support Centre in real time, during drilling. Updated information is displayed on the existing geological model of the field, with actual data compared against projected data, analysed, and, if necessary, the well trajectory corrected on that basis in order to fall within the target zone. Then, as new data is received, the cycle is repeated, allowing uninterrupted control over drilling operations.
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.
