On the 2nd and 3rd of April, COSL's five technical projects of LWD-SPOTE, LWD neutron, LWD density, LWD sonic and formation testing while drilling passed CNOOC's inspection. The inspection committee considered that the five projects completed all the researches as stated in the contracts, and met the standards it required. The projects also produced satisfactory results with complete data for inspection and reasonable research expenses.

The projects, which passed the inspection, had undergone early drilling tests by an expert committee. They laid the technological groundwork for further marine applications.
