Oil production at the Chevron -led Tengiz field, Kazakhstan’s largest, fell sharply on May 26 as a result of an accident, two industry sources told Reuters yesterday.
The first two sources said daily output at Tengiz, which had only just recovered from a previous incident, fell to between 5,000 metric tonnes and 10,000 tonnes on Tuesday, compared with the usual level of 125,000 tonnes or 995,000 barrels.
Speaking on condition of anonymity due to the sensitivity of the situation, the sources did not give any details of the accident or its cause, but said they expected oil production to be gradually restored within roughly a week. A third source said output at the field, operated by Tengizchevroil, stood at around 82,000 metric tonnes on May 27.
