Russian oil firm Gazprom Neft has commenced production at the Otdalennaya group of fields located in the Yamalo-Nenets Autonomous Okrug.

In this regard, its subsidiary Gazpromneft-Noyabrskneftegaz had concluded the drilling and testing of the first production well at the Zapadno-Chatylkinskoye field which is estimated to have over 40 million tonnes of oil reserves in place.

According to Gazprom Neft, the constructed well has a total length of 4.14km which includes a 730m-long horizontal section.

During testing of the first production well at the West-Chatylkinskoye field, the initial production rate was found to have crossed over 500 tonnes per day of anhydrous low-sulphur oil.

Gazprom Neft expects the daily production rate of new wells to surge up to 700 tonnes upon completion of the construction of transport infrastructure.

Gazprom Neft first deputy CEO Vadim Yakovlev said: “The operational drilling programme at the Zapadno-Chatylkinskoye field will continue throughout 2018. We plan to build eight production wells here, ensuring production of up to 500,000 tonnes of oil per year.

“According to our calculations, peak production across the entire Otdalennaya group of deposits will be reached in 2023–26, at approximately two million tonnes of oil per year.”

The Zapadno-Chatylkinskoye oil field is part of a remote group of deposits found in the in the southern part of the Yamalo-Nenets Autonomous District. It brings together the different assets held by Gazprom Neft in the region.

Gazprom Neft says that the position and occurrence of hydrocarbons at the Zapadno-Chatylskinskoye deposit are identical to those at the Chatylkinskoye oil field.

Gazpromneft-Noyabrskneftegaz has started developing the Chatylkinskoye field which has seen high daily inflows along with a low rate of natural depletion.
