HOUSTON, Aug 13 (Reuters) - A court officer in Delaware

overseeing an auction of shares in the parent of Venezuela-owned

refiner Citgo Petroleum has requested an adjournment of the sale

process' final hearing, originally scheduled for next week to

decide the auction's winner, a court filing showed on Wednesday.

The request comes after at least two unsolicited bids were

recently submitted by groups including affiliates of hedge fund

Elliott Investment Management and commodities house Vitol, even

after the court officer had recommended a different bid by a

unit of miner Gold Reserve ( GDRZF ).
