China National Offshore Oil Corporation (CNOOC) said that the company has successfully drilled two new oil and gas discoveries, Bozhong 2-1 well and Qinhuangdao 29-2 well. Both the wells are located offshore China.
According to CNOOC, the discovery well Bozhong (BZ) 2-1-2 penetrated oil pay zones with total thickness of 50.9m. The well drilled to a total depth of 3,910m, with water depth of about 26m. The well was tested to flow at an average rate of 1,270 barrels of oil and 393 thousand cubic feet of natural gas per day via a 11.91mm choke.
In addition, the discovery well Qinhuangdao (QHD) 29-2-1 is located on QHD 29-2 structure, with a total depth of 3,991m. It encountered oil pay zones with total thickness of 34.7m and gas pay zones of 47.9m. The water depth averages approximately 27m, said the company.
CNOOC has carried out drill stem test for four layers, and the well flowed at an average rate of 3,930 barrels of oil and 15.2 million cubic feet of natural gas per day.
Zhu Weilin, Executive Vice President of CNOOC and GM of Exploration Department, said: These results brought a good start-up for the company’s exploration activities in 2009. Both of the structures are on large scale with thick oil pays, and contain light crude. It is of the significance to improve the current heavy oil dominant asset profile in Bohai Bay.
