Intro
Who Dat is a deepwater spar platform located in Mississippi Canyon Block 547 in the Gulf of Mexico. First production began in 2011. The facility produces oil and gas and serves as a host for subsea wells, exporting hydrocarbons via pipelines connected to regional infrastructure.
Field
The Who Dat Field lies in the Mississippi Canyon area and produces from Miocene deepwater sandstone reservoirs. The field is moderate in size and developed using subsea wells tied back to a central spar platform.
Facilities
The Who Dat spar is installed in approximately 3,100 ft (945 m) of water and supports subsea production wells connected via flowlines and steel catenary risers. The facility includes separation systems, oil stabilization, and gas compression. Oil is exported via a 12-inch pipeline connecting into the Poseidon oil system, delivering crude to shore. Gas is exported via a 10-inch pipeline into regional Gulf of Mexico gas networks. Produced water is treated prior to discharge. The platform includes water injection systems for reservoir support. Power generation is provided by gas turbines. The spar is moored using a catenary mooring system. Subsea infrastructure includes manifolds and electro-hydraulic control systems for remote operation.
