REMINGTON OIL AND GAS CORPORATION APPARENT HIGH BIDDER
ON 8 GULF OF MEXICO OFFSHORE LEASE BLOCKS

DALLAS, TX, March 16, 2006 — Remington Oil and Gas Corporation (NYSE: REM) was the apparent high bidder on eight (8) offshore lease blocks at the OCS Sale 198 held in New Orleans, Louisiana, yesterday. The Company’s net financial exposure, if all blocks are awarded, totals $15 million. Remington will operate all 8 blocks if awarded.

Of the 8 lease blocks, 4 lease blocks were in water depths that varied from 50 feet to 100 feet, and 4 lease blocks were in water depths that varied from 2,400 feet to 3,200 feet.

Remington Oil and Gas Corporation is an independent oil and gas exploration and production company headquartered in Dallas, Texas, with operations concentrating in the onshore and offshore regions of the Gulf Coast.

Statements concerning future revenues and expenses, production volumes, results of exploration, exploitation, development, acquisition and operations expenditures, and prospective reserve levels of prospects or wells are forward-looking statements. Prospect size and reserve levels are often referred to as “potential” or “un-risked” reserves and are based on the Company’s internal estimates from the volumetric calculations or analogous production. Other forward-looking statements are based on assumptions concerning commodity prices, drilling results, recovery factors for wells, production rates, and operating, administrative and interest costs that management believes are reasonable based on currently available information; however, management’s assumptions and the Company’s future performance are subject to a wide range of business, mechanical, political, environmental, and geologic risks. There is no assurance that these goals, projections, costs, expenses, reserve levels, and production volumes can or will be met. Further information is available in the Company’s filings with the Securities and Exchange Commission, which are herein incorporated by this reference. Information in this document should be reviewed in combination with the Company’s filings with the Securities and Exchange Commission and information available on the Company’s website at www.remoil.net.
