Energy Development Corp. China Inc. (EDC), an indirectly wholly owned subsidiary of Noble Affiliates Inc., Houston, has selected Houston-based Paragon Engineering Services Inc. to assist it in developing the Cheng Dao Xi Block A field in the southern half of China's Bohai Bay, Paragon said Monday.
Noble Affiliates announced recently it was given the go-ahead to develop the field (OGJ Online, Oct. 31, 2000).
Through a contract valued at $2.6 million, Paragon will perform engineering, design/drafting, and procurement services for the entire platform, including jacket, deck, and topsides equipment, for EDC/Noble, operator of the field. Paragon has completed preliminary design and is currently performing detailed design of a central drilling/production platform to be installed in 25 ft of water.
The Cheng Dao Xi field is located 5 miles off the northern coast of Shandong Province in Bohai Bay.
Paragon expects the design work to be complete by the end of the year. Activities include structural engineering, facilities engineering, instrumentation/electrical and utility design as well as procurement of all equipment, structures, fabrication, and installation. The large, six-pile fixed platform calls for a float-over deck installation, which Paragon said will make the installation of the 3,100-ton integrated deck more economic.
The facility also features two well bays completely outboard the main platform, allowing for simultaneous drilling by two different jack-up rigs. Each well bay has 12 slots.
EDC/Noble will place the platform over an existing well previously drilled, completed, and tested.
The platform will be designed to produce 8,500 b/d of oil. With minor modifications and equipment additions, a higher capacity of 12,000 b/d of oil can be achieved. Produced fluids will consist of high-viscosity oil being produced with a very high volume of formation water. The oil is a 20� API sandy crude with a very tight, high-water-content emulsion.
Topside equipment will de-emulsify production, heat it, and treat it, then transport the contract quality crude to shore. Excess water will be reinjected into the formation as necessary to maintain production reservoir bottom hole pressure and optimum oil production recovery.
Paragon will install two 5-mile subsea pipelines, both double-walled and insulated for the cold temperatures, from the platform to an onshore terminal adjacent to the existing Shengli Hai San terminal. Shengli Engineering Research Institute will perform detailed design of the pipelines.
