Murphy Oil Corporation’s Thunder Ridge exploration well located in Mississippi Canyon Block 737 has been temporarily plugged and abandoned. The primary objectives found wet sands, with a secondary shallower objective encountering a small oil accumulation. The exploration well and subsequent sidetrack were drilled in over 6,100 feet of water.

Post-drilling analysis will continue to determine if the resource found can be commercially viable as a tie-back to another facility. Thunder Ridge lies in close proximity to the Company’s recently sanctioned Thunder Hawk development that will include a stand-alone semi-submersible floating production unit.

Murphy owns a 37.5% working interest in the field and serves as operator. Partners are Dominion Exploration & Production, Inc., a subsidiary of Dominion Resources (NYSE: D), 25%, Hydro Gulf of Mexico, L.L.C., 25%, and Marubeni Offshore Production (USA) Inc., a subsidiary of Marubeni Corporation, 12.5%.
