Gazprom Neft boasts major oil find in the Sea of Okhotsk

GazpromneftSakhalin, which is a subsidiary of Gazprom Neft, has completed drilling a wildcat at its Ayashsky license block situated on the Okhotsk Sea continental shelf.

The company reported last week that a new oil and gas field had been discovered with estimated initial in-place reserves of 255 Mtoe (mln tons of oil equivalent) and added that a detailed evaluation of the reserves would be completed by the middle of 2018.

Alexander Dyukov, CEO of Gazprom Neft, pointed out that the development and exploration of all offshore license blocks in the company’s portfolio will be continued and that this major oil field discovery in the Sea of Okhotsk proved their experience and allowed them to re-evaluate prospects to develop offshore projects.

The company representatives reported that the well had been constructed during a tiny window of an ice-free period at the Okhotsk Sea, and it had been completed on time and without incidents.

According to the company, the decision to start drilling in the Ayashsky prospective horizon was made based on 3D seismic data. The survey data acquired during offshore operations at the Sea of Okhotsk was thoroughly analyzed before the drilling program was developed. Coring samples from as deep as 162 meters were taken from estimated reservoirs to construct this 2,700-m deep well, in addition to open-hole and cased-hole geophysical and hydrodynamic measurements.

The Ayashsky block in the Okhotsk Sea operated by Gazpromneft-Sakhalin is part of the Sakhalin-3 project. The license block is situated in the northeast of the Sakhalin’s continental shelf approximately 55 km offshore.
