Sakhalin Energy Uses the First Russia Manufactured Downhole Drilling Motor in Project History

For the first time in the history of Sakhalin-2 field development Sakhalin Energy used a downhole drilling motor (DDM) manufactured in Russia. More than a thousand metres has been drilled using this motor in the PA-B well.

The successful application of this equipment has become yet another step towards increasing the Russian content in the Sakhalin-2 project.

The company supports the state policy of import substitution while taking into account technical features of the Sakhalin-2 project and capabilities of Russian manufacturers. The downhole drilling motor produced by the Russian company Radius-Service is already being used by other oil and gas companies including one of our shareholders. “Sakhalin Energy was among the first to use this equipment for offshore drilling,” says Timur Gafarov, Sakhalin Energy Technical Director.

Before the motor installation, all the necessary preparations were made at the platform, including inspection by the manufacturer’s specialists of its compatibility with substances used in the wells. All this enabled effective and safe operation of the equipment.

In the future, Sakhalin Energy intends to use domestically manufactured downhole drilling motors at other oil and gas platforms of the Sakhalin-2 project.

PA-B is the largest platform of the Sakhalin-2 project. Since late 2008, the platform has been producing oil and associated gas from the Piltun Area of the Piltun-Astokhskoye oil field.

As of the end of 2020, the PA-B platform had 20 production wells, eight water injection wells, and two cutting re-injection wells.
