Central to Rosneft’s plan to revive production at Yuganskneftegaz is the development of deposits known in Russian as “hard-to-recover resources”.
The terminology is important: until 2014, such resources were often described by western and Russian companies in English as “shale”. When the US and Europe imposed sanctions restricting sales of equipment and services to Russian shale oil projects, many feared they would scupper development of such projects.
But Russian executives say only the giant Bazhenov formation, which is estimated by the US energy department to hold 75bn barrels of oil, has been affected. Meanwhile, work on other “hard-to-recover” deposits, such as the Tyumen or Achimov, has continued. Like shale, these are low-permeability formations which require horizontal drilling and fracking to exploit, but the executives say they are geologically distinct from shale and therefore do not fall under the
sanctions.
There are some things connected to the Bazhenov which fall under sanctions,” says Alexander Vitevsky, chief geologist at Yuganskneftegaz. “But in fact the main part of our hard-to-recover resources is not the Bazhenov: it is prospects in the Tyumen and Achimov formations.” He says the Bazhenov accounts for an “absolutely insignificant” share of Yuganskneftegaz’s resources.
Mr Tatriev predicts that output of hard-to-recover oil atYuganskneftegaz will increase more than threefold to 200,000 b/d by 2020.
At well pad number 258, Mr Stefanishin rattles off a list of western service companies working with Rosneft. “We have working with us very successful companies — Baker Hughes, Halliburton — we’re using their rotary steerable systems for drilling horizontal sections.”
There are signs that Rosneft is preparing to use Yuganskneftegaz as a model for its other brownfield assets. It has lifted drilling at Samotlorneftegaz, another western Siberian subsidiary, by 50 per cent this year. “We’re applying the same strategy as Yugansk — the plan is to turn around all these brownfields,” Eric Liron, Rosneft’s first vice-president, told investors earlier this year.
