Exploratory and development drilling is advancing in western Siberia's Kalchinskoye field area.
Black Sea Energy Ltd., Calgary, said three rigs are working on the Tura project, and another five rigs soon will begin drilling for Tura Petroleum Co., 50% owned by Black Sea.
"Our Tura joint venture is on schedule for our planned second quarter drilling program of three exploratory wells and three development wells," said Clint Hussin, Black Sea president.
The company plans two new exploratory wells and three new development wells in the third quarter.
Kalchinskoye operations
The Tura project involves 75,000-acre Kalchinskoye field and surrounding 1 million-acre North Kalchinskoye exploration block.
Black Sea's share of proved reserves is 27 million bbl, and another 133 million bbl are classified as probable reserves.
The project has 30 producing oil wells and six water injection wells.
Five wells in the Kalchinskoye pool were hydraulically fractured recently, resulting in increased flow rates of 255-1,430 b/d/well.
Enhanced production has aided in increasing total field output to the current rate of 6,100 b/d, up from an average 4,680 b/d at the end of the first quarter.
Oil is being sold at $13.20/bbl on the domestic market, well ahead of earlier projections of $10.55/bbl. Sales totaled 160,800 bbl in May, officials said, and they estimate June sales will total 182,750 bbl.
In July, a portion of the production will be sold on the export market at world prices.
Other work
Black Sea said work is proceeding on schedule on the Kuban project, its second joint venture in Russia.
Kuban Technologies, 50%-owned by Black Sea, has begun an incremental oil recovery project that's initially focused on rehabilitating 400 wells in Anastaskievsko-Troitskoye field in southern Russia, near the Black Sea.
The company is now conducting its first well workover, the first of an initial five-well program designed to evaluate specific gas-coning and water shutoff technologies.
