Combining several operations limits production losses at King and King West Fields.
Amrin F. Harun, BP America*
King and King West oil fields are in the GOM and 100% BP operated. The fields include three subsea wells: King D5 and D6 wells and King West D3 well, located in 5,200-ft to 5,400-ft water depths. The wells are tied back to the Marlin TLP in 3,200-ft water depth.
D3 well is connected to D5 well through a 2.3-mi, 6-in. by 10-in. pipe-in-pipe flowline. D5 and D6 are connected to the TLP via 17-mi, 8-in. × 12-in., dual actively heated west and east flowlines, respectively, Fig. 1. A remotely-operated, subsea-pigging valve located close to D6 is normally open.
D5 and D6 are producing from the same reservoir, while D3 produces from another reservoir. For reservoir management purposes, D3 is equipped with a SubSea MultiPhase FlowMeter (SS MPFM) located in a jumper between the wellhead and the flowline.
The Marlin TLP processes the production stream coming from three dry-tree wells (two oil and one gas) and five subsea wells (three oil and two gas). The fluids go to three, three-phase separators (HP, Test and IP) set at the same pressure, Fig. 2. The oil flows through the LP separator and the gas goes to the compression system before going to the export system. The produced water is treated and dumped overboard.
D3, D5 and D6 normally flow to the IP separator. However, the topside piping and manifold systems allow any well to flow to any separator, providing it does not upset the plant, mainly the water treatment process. D5 and D6 oil and gas production is allocated by the IP separator measurement after subtracting D3 well production, measured by the SS MPFM..
