Chevron

CHEVRON's earnings for the fourth quarter of 2013 are expected to be comparable with third-quarter results from the same year.

The major player's upstream operations took a hit as planned downtime and maintenance occurred across a number of projects in the Gulf of Mexico, Australia and Angola.

Meanwhile, downstream returns were up due to the absence of planned maintenance in the third quarter at the El Segundo, California, refinery.

Statoil

A gas leak at Statoil's Snohvit LNG plant at Melkoya Island, off Hammerfest, has attracted an investigation from the Petroleum Safety Authority of Norway.

The PSA has been told that the leak was substantial, with actual numbers unknown after a pump in the process plant failed. This was followed by a condensate leak from a heat exchanger after fixing the first leak.

Statoil said all necessary repairs were complete and that it would undertake its own investigation into the incident.

Range

Range Resources is expecting the $US30 million ($A33.3 million) sale of its Texas assets to be finalised by the end of the month.

The announcement comes after significant delays in the completion of the sale due to the buyer undergoing unexpected changes required for corporate restructuring.
