The company also posted sales revenue of $114.1 million, compared to $135.3 million for the first half of 2012. This was generated from 1.1 million barrels of oil equivalent, at an average realized oil price of $104.21 per barrel compared to $118.33 per barrel last year.

Production was also down 5% to 1.17 million barrels of oil equivalent, primarily due to natural field decline from five producing fields in Australia, China and the UK.
