Gazprom Neft has conducted what it says is the first hydraulic fracturing ever on Russia’s Yamal Pensinsula at geologically complex Novoport oil and gas condensate field.
A subsidiary performed five frac jobs in Jurassic reservoirs in four wells—single fracs in vertical wells and a multistage frac in a horizontal well.
Gazprom Neft said all the wells were placed on stream, with total production 2.5 times the predicted rate. All the wells are on primary recovery.
The company has begun drilling the first of three wells planned at a second well pad.
Denis Kashapov, executive director of the Novy Port branch of Gazpromneft Razvitiye, the Gazprom Neft subsidiary, said further hydraulic fracturing of Novoport Jurassic reservoirs is planned.
Novoport is the largest oil and gas condensate field under development in the Yamal area, with explored and estimated reserves of 230 million tonnes of oil and 270 billion cu m of gas.
