The Who Dat field is located on Mississippi Canyon Blocks 503, 504 and 547 in the Gulf of Mexico in 3,000 feet (914 meters) of water. LLOG operates the field with a 67.5% interest.
The Ocean Victory semisub discovered the LLOG OCS-G-27277 well in December 2007. The discovery well found more than 380 feet (116 meters) of gas and oil pay zones in four separate reservoir packages. The field was further appraised by two wells testing additional targets in 2010. Once appraisal operations were completed, Who Dat was deemed commercially viable.
Who Dat is primarily an oil field consisting of nine stacked, amplitude-supported reservoirs in a salt withdrawal mini-basin. The wells targeted reservoirs ranging in depths from 12,000 to 17,000 TVD. Collectively, the three ...

The field was further appraised by two wells testing additional targets in 2010. Once appraisal operations were completed, Who Dat was deemed commercially viable.
Who Dat is primarily an oil field consisting of nine stacked, amplitude-supported reservoirs in a salt withdrawal mini-basin. The wells targeted reservoirs ranging in depths from 12,000 to 17,000 TVD. Collectively, the three wells penetrated more than 700 feet (213 meters) of net pay in nine distinct reservoirs. It is believed the field holds more than 300 MMboe.
Field Development
The development plan for Who Dat, moored on MC 547 in 3,100 feet (945 meters) of water, consisted of completing three existing subsea wells, drilling an additional two wells and producing the wells through a subsea system capable of handling up to 12 wells. The wells should flow through three subsea manifolds to the OPTI-EX FPS through flexible risers.
The OPTI-EX FPS, delivered to LLOG in July 2011, is capable of producing up to 60,000 bopd, 150 MMcf/d and 40,000 bwpd.
Initial production from the Who Dat field commenced on December 9, 2011. LLOG is ramping up production and expects to achieve a rate of 20, 000 bopd and 22 MMcf/d from the three existing wells.
The development plan for the field calls for the company to drill nine additional wells, which would fully utilize the 60,000 bopd and 150 MMcf/d capacity of the floating production system.
