LLOG producing from Who Dat oil, gas field in Gulf of Mexico

LLOG Exploration Co. LLC started production from Who Dat oil and natural gas field on Mississippi Canyon (MC) Blocks 503, 504, and 547 in the Gulf of Mexico. LLOG expects to ramp up production to 20,000 b/d and 22 MMcfd from three existing wells.

The field development plan calls for drilling nine additional wells for fully loading the 60,000 bo/d and 150 MMcfd capacity of the floating semisubmersible production unit that is moored in 3,100 ft of water on MC Block 547.

Who Dat, discovered in December 2007, will produce from 10 stacked Pliocene and Upper Miocene reservoirs at 10,000-17,000 ft. On test the zones that are mainly oil tested 17-26° gravity oil with 400-1,300 GORs. Reservoir pressures ranged from 6,000 to 12,500 psi.

LLOG also plans to start production from Mandy in 2,465 ft of water on MC Block 199 and Goose in 1,625 ft of water on MC Block 751 in the first and second quarters of 2012, respectively.

The company expects Mandy to produce at an initial rate of 15,000 bo/d and 12 MMcfd of gas to W&T Offshore's Matterhorn tension leg platform. LLOG estimates that Mandy will recover 10-30 million boe.

Goose is a Spinnaker Petroleum late-1990s discovery that LLOG plans to complete as a subsea tie-back to its Valley Forge field manifold on MC Block 707.

The well encountered gas-condensate in three sands and tested 8,000 b/d of liquids and 28 MMcfd of gas.
