The field is producing at a volume of more than 2,200 barrels of oil per day from four wells. LD 5-2, with a water depth of approximately 30 meters, is located in Liaodong Bay of Bohai Bay. It is adjacent to the producing field Suizhong 36-1. The peak gross production capacity is designed at 9,600 barrels of oil per day with 22 producing wells on line. LD fields, which currently consist of three fields, LD 4-2, LD 10-1 and LD 5-2, have come on stream successfully. Thanks to the joint development and sharing with Suizhong 36-1 of its producing facilities, the fields will deliver better economic returns. Mr. Liu Jian, Executive Vice President of the Company commented, "CNOOC Limited discovered and developed the LD fields independently. It takes only three years to bring them on line. This is another piece of evidence of the Company's capability to optimize the economic margin via quick development and sharing of existing facilities." The Company holds 100% interest of the LD fields and acts as the operator.
