Novatek makes new gas condensate FID in West Siberia

Russia’s largest independent gas producer, Novatek, announced Monday the final investment decision (FID) for an exploration and pilot production project in the onshore West-Yurkharovskoye license in West Siberia, Kallanish Energy reports.

The decision was made after a subsidiary successfully completed testing the Jurassic reservoir at well #135R on the license. The well was drilled using multi-stage hydro-fracturing at a depth of 4,100 meters with abnormally high reservoir pressure of 820 atmospheres and co-mingled production from two separate Jurassic horizons.

“This was the first time such a well completion for an over-pressurized Jurassic reservoir was applied in Russia,” Novatek said, adding the well has been naturally flowing with a gas condensate mixture flow rate of 650,000 cubic meters per day.

“The commercial viability of the deeper Jurassic deposits was confirmed, and, correspondingly, an investment decision was made to commence an exploration program and pilot production from this new project site as part of the Yurkharovskoye production center,” the company said.

Novatek didn’t disclose details of the project such as the estimated timeframe and investment amount.

The giant Yurkharovskoyef gas condensate field is one of Russia’s largest producing gas fields, according to Wood Mackenzie. Its western part is located on the Taz peninsula, while the central and eastern parts are situated in the Taz River.
