ConocoPhillips drilled the PL 19-9-1 exploration well, 2 mi east of the PL 19-3 field in January 2003. The well encountered 31 m of net hydrocarbon pay in Lower Minghuazhen and Guantao sandstone reservoirs. The discovery and the adjacent structures will be part of PL 19-3 Phase II development.

ConocoPhillips completed drilling on the PL 13-1-1 exploration well, 18 mi north of the PL 19-3 field, in March 2003. The well encountered 40 m of net hydrocarbon pay in Lower Minghuazhen and Guantao sandstone reservoirs. The company plans to drill additional wells to appraise the discovery and the structures in the same trend.

ConocoPhillips continues to have success with its Bohai Bay exploration program. These two wells bring the number of discoveries in Bozhong 11/05 to seven.

Phase I of the PL 19-3 development began production in December 2002, and the field is producing 30,000 b/d. Phase I facilities include a 24-slot wellhead platform and an FPSO facility. Phase II development plans are under way and will incorporate knowledge gained from the Phase I drilling and production results.

ConocoPhillips and Cnooc signed a petroleum contract in December 1994 granting ConocoPhillips the right to explore block 11/05, a 2.3 million-acre area in Bohai Bay. ConocoPhillips operates the block with a 100% working interest in all fields discovered to date with the exception of PL 19-3 development, in which the company has a 49% interest. Cnooc elected to participate in the PL 19-3 Phase I development with a 51% working interest, and has the right to acquire up to a 51% working interest in any development in the Bozhong 11/05 block.
