July 31 (Reuters) - Origin Energy ( OGFGF ) reported a 7%

sequential decline in its fourth-quarter revenue from its stake

in the Australia Pacific LNG (APLNG) project on Wednesday due to

lower LNG sales volumes and reduced average realised LNG prices.

The energy retailer said that its share of revenue from

APLNG, a joint venture with U.S. based oil and gas giant

ConocoPhillips ( COP ) and China state-owned Sinopec

, fell to A$590 million ($385.74 million) for the

three months ended June, as compared with A$633 million in the

previous quarter.
