State owned Kuwait Oil Company (KOC) said it had contained a minor leak at its biggest oilfield with no impact on exports, state news agency KUNA reported on Sunday.
OPEC member Kuwait is still estimating how much oil leaked at the al Ahmadi field, part of the world's second largest oilfield at Greater Burgan.
The leak occurred on Sunday morning from a pipeline, KUNA cited a KOC official as saying.
It was controlled in no more than an hour, the agency said.
The world's fourth largest oil exporter pumped 2.28 million barrels per day (bpd) in December, according to a Reuters survey.
KOC runs domestic oil output and exploration. (Reuters)
