London-listed Kazakh oil and gas producer KazMunaiGas Exploration Production said Wednesday its oil production rose 11% on the year to 257,000 barrels a day, or 6.28 million metric tons, in the first half of this year.

"The increase in production results from the acquisition of a 33% stake in PetroKazakhstan, which accounts for 733,000 tons," the company said in a statement.

KMG EP's core facilities Uzenmunaigas and Embamunaigas produced 4.32 million tons, or 175,000 barrels a day, which is 2% less than in the same period a year earlier.

"The decline in production was mainly caused by the failure to perform well service operations and oil field equipment repair on time amid a strike by Uzenmunaigas workers over the period from March 4 through March 18 when some of the workers refused to get back to work," KMG EP said.

The company produced 11.5 million tons of oil, or 232,000 barrels a day, in 2009. Its proved and probable reserves stood at 1.7 billion barrels last year.

KMG EP's majority shareholder is Kazakh state oil and gas company KazMunaiGas.
