BHP revealed on Wednesday that output for the 12 months to 30 June totalled about 240 million barrels of oil equivalent, 6% less than it produced in the 2015 financial year.

The company blamed the deferral of development activity at its onshore US operations for the decline in production and offsetting the performance of its conventional production.

Along with sliding production, BHP has had to contend with falling commodity prices, with the company achieving an average oil and condensate price of US$39 per barrel, down 43% on the US$68 per barrel achieved over the previous 12-month period.
