Reliability of Russian-made rotary steerable drilling system confirmed by Gazprom Neft
Gazprom Neft has successfully tested a Russian-made rotary steerable system (RSS) at its Yuzhno-Priobskoye field. This equipment is designed for drilling complex-structured wells, with extensive horizontal and directional sections. Rolling-out this technology will significantly reduce equipment costs and improve cost effectiveness in well construction.
Rotary drilling differs from traditional drilling in that the entire drill string, rather than just the drill bit, rotates. Rotary steerable systems mean the drilling trajectory can be adjusted quickly, ensuring optimum accuracy in hole making and production efficiency.
The RUS-GM-195 well-drilling RSS has been developed by Russian scientific and production enterprise BURINTEKH and tested at Gazprom Neft assets, the first prototype having been tested at the Yuzhno-Priobskoye field in February 2017. Final testing in October 2020 has confirmed the reliability of this domestically produced system — a well-section of more than 1,900 metres having been drilled using the RUS system.
As is the case for existing imported RSS, this new solution can be used for drilling all kinds of wells. The RUS-GM-195 is expected to go into serial production in 2021.
“I am delighted by the successful testing of a Russian rotary steerable system — in one of the most commonly used sizes, used in more than 10% of the domestic drilling market. Going forward, we will be able to move over to developing more compact and high-tech standard sizes, more than covering market demand for Russian technologies”, — Deputy Minister for Industry and Trade of the Russian Federation Mikhail Ivanov.
“We work with hard-to-recover reserves, which comprise an increasingly important proportion of our portfolio, year after year. Developing these successfully demands high-tech equipment. Utilising domestic solutions mean we can cut costs in drilling complex wells and improve project viability — that is to say, our competitiveness: something that is critically important in today’s economic environment. We are developing and deploying a multitude of new technologies, tools and equipment, independently and with partners. In addition to which, we were the first in the industry to roll-out a ‘technology test-site’ format, giving Russian companies the opportunity to test their cutting-edge technologies. This is not only improving stability throughout the entire industry, reducing dependence on imported equipment, but also means we are getting tools appropriate for the specific geological and other characteristics of Russian fields”, — Deputy CEO for Exploration and Production, Gazprom Neft Vadim Yakovlev.
“BURINTEKH has been producing high-tech drilling and well-workover tools for more than 20 years. Successful testing of the RUS-GM-195 system — the stringent restrictions of the pandemic notwithstanding — has meant successful testing across the entire company, whose teams have been able to mobilise, adapt and find their way through to a successful outcome. We have created a unique product, that can be used at all kinds of wells, is reliable, and easy to operate. The Russian Federation’s Industrial Development Fund, from whom we received considerable financial support, in their allocating a loan to develop the RUS-GM-195 system — has given life, and considerable promise — to this project”, — CEO, BURINTEKH Gniyatulla Ishbaev.
