April 30 (Reuters) - Beach Energy BPT.AX said on Friday it has undertaken an urgent review of its reserves across the Western Flank oil and gas fields after a recent decline in oil production.
The company downgraded its annual pro-forma production forecast to 25.2 million barrels of oil equivalent (MMboe) to 25.7 MMboe from 26.5 MMboe to 27.5 MMboe earlier.
Beach also withdrew its five-year outlook.
