CNOOC Liuhua 4-1

LIUHUA 4-1 (LH4-1) oil field is located in the South China Sea, approximately 215km from Hong Kong and 240km for Shenzhen.  It will be tied back to the existing LH11-1 infrastructure about 11km southeast of the field.

Standard EHXT configuration will be employed for this project.  Each well will be completed with two Electrical Submersible Pumps (ESPs) requiring the Tree Cap and Tubing Hanger to provide high voltage electrical connections to allow power supply to the ESPs.  The Tree Cap will also have a power switch to allow switching between the two ESPs.

Dedicated Subsea Control Modules on each tree equipped with MRM modems will allow EH control of the wells by the topside mounted Subsea Production Control System.  Well jumpers with FMC Torus III connection system will connect each well to a production manifold.


Production from the LH4-1 field will be mixed with the LH11-1 production via a Bridging Manifold, which is also provided by FMC on a separate contract.
