BZ 3-2, with an averaged water depth of 25 meters, is located in the central part of Bohai Bay and about 20 kilometers southeast of producing field Qinhuangdao 32-6.

Mr. Chen Bi, Executive Vice President of the Company, said, "We have accumulated a set of effective technologies for marginal fields based on rolling development and regional development during our offshore operations.
