ALMATY, Oct 1 (Reuters) - Kazakhstan expects its oil production to stay around 2013 levels until 2016, when it hopes to restart the giant Kashagan oilfield halted by an industrial accident, a senior Kazakh official said on Wednesday.
The Central Asian nation aims to produce 81.8 million tonnes (1.64 million barrels per day) of crude this year, Deputy Energy Minister Magzum Mirzagaliyev told reporters on the sidelines of an international oil and gas conference.
“Next year production is expected to be at the 2014 level,” he added.
The second-largest ex-Soviet oil producer after Russia raised its oil output to 81.7 million tonnes last year from 79.2 million tonnes in 2012.
A further increase in production after the 3 percent rise last year has been thwarted by delays at the giant Kashagan oilfield in the Caspian Sea.
Kashagan, the world’s biggest oil find in recent decades, was launched in September last year after repeated delays and cost overruns. But its output was halted just a few weeks later after gas leaks were detected in its pipelines.
Now it is not expected to resume output before the first half of 2016. “The fact remains ... that in any case production at Kashagan finally began, there is oil in the reservoir, and we hope that once we have replaced the pipelines, output will resume in 2016,” Mirzagaliyev said.
Official data show that Kazakhstan’s oil output edged down to 53.6 million tonnes in January-August this year from 54.0 million in the same period of 2013.
“We expect that we will be able to meet our production target (for 2014),” Mirzagaliyev said.
“Today we are looking for resources (to keep output stable). In particular, production at (the) Tengizchevroil venture is crucial,” he said.
Tengizchevroil (TCO), Kazakhstan’s largest producer, is a Chevron-led joint venture which operates the mammoth Tengiz onshore oilfield in the west of the country.
TCO is due to begin scheduled repair and maintenance work this month on the Tengiz field. A senior Kazakh energy official said in July the repair work was expected to last for 45 days.
“We expect that this planned repair work will be done in a fast tempo and we believe that we will achieve planned output there,” Mirzagaliyev said.
“Our latest data show that this repair may be conducted in just 23 to 28 days.”
Mirzagaliyev said TCO was forecast to produce “around 27 million tonnes” of oil this year.
Last year the joint venture produced a record 27.1 million tonnes, up from 24.2 million in 2012.
Chevron holds 50 percent of TCO, while Exxon Mobil owns 25 percent, Kazakh state oil company KazMunaiGas 20 percent and Lukarco, controlled by Lukoil, the remaining 5 percent. (Writing by Dmitry Solovyov; Editing by Tom Hogue and Mark Potter)
