MOSCOW, October 30 (Itar-Tass) —— One of Russia’s leading oil producers, Rosneft company, reported that it had explored a new oil and gas field, Lebedinskoye, on the Sakhalin shelf, and it would be profitable to develop the field from the shore.

“As a result of the exploration drilling of hole No 1 at the Lebedinskoye licences block, located on the shelf of the Sea of Okhotsk, specialists of the company yielded an oil flow to surface up to 150 cubic metres a day,” the company said in its report.

“Recoverable oil resources of the southern sector of the field are estimated at more than 3.3 million tonnes under Russia’s classification,” the report said.

“The fruitful drilling at the Lebedinskoye block confirmed the prospects of further development of this part of the Sakhalin offshore zone,” the company stressed in the report.

“The company links additional possibilities of that licensed block with the northern sector of the Lebedinskoye block,” Rosneft said, adding, “With this in mind, the company plans to start construction of the second exploratory well Lebedinskoye No 2 at the aforesaid area in the middle of November.”

While carrying out the exploration activities, the company observed all obligations envisaged by the licence and implemented all environmental protection measures in full. During the Lebedinskoye No 1 hole drilling, specialists of the company used several unique technical novelties. For instance, they drilled a well with considerable vertical deviation. During the drilling, workers carried out a record high number of formation pressure measurements (57). The use of new methods and technologies made it possible to decrease the well construction period.

The Lebedinskoye block is located three kilometres of the shore in the shallow-water part of the Sea of Okhotsk and borders on two fields – Odoptu (Sakhalin-1 project) and Odoptu-Sea-Northern Dom (Rosneft-Sakhalinmorneftegaz company).

According to DeGolyer & MacNaughton, the field’s prospective reserves are estimated at 12 million tonnes of oil and 5.4 billion cubic metres of gas.

Rosneft received the licence for the exploration of hydrocarbons at the Lebedinskoye field in 2007. From 2009, a special subsidiary, Rosneft-Shelf-Far East, is involved in the management of works over the project.

Rosneft is the leader of Russia’s petroleum industry, and ranks among the world’s top publicly traded oil and gas companies. The company is primarily engaged in exploration and production of hydrocarbons, production of petroleum products and petrochemicals, and marketing of outputs.
