Abstract: In recent years, China National Offshore Oil Corporation (hereinafter referred to as CNOOC for short) has achieved fruitful oil and gas exploration results. Domestically, it sets up new record of oil and gas exploration discovery and its proved reserves has increased stably. It has acquired a series of major hydrocarbon exploration breakthroughs in the active fault belts in the Bohai Sea, the high temperature and high pressure areas in western South China Sea and the deep water areas of northern South China Sea. Abroad, its recoverable reserves of overseas exploration equity increases stably, and four large-scale reserve zones are formed, e.g. Sahara of North Africa and both sides of South Atlantic. As the progress of integrated exploration, development and production of unconventional oil and gas is sped up, its proved reserves and production increase fast. As for the domestic exploration in the near future, CNOOC will advance deep zone exploration in the Bohai Sea, proceed oil and gas exploration in the central south of the South China Sea in good time and make more efforts to research heavy oil reservoirs and low porosity-low permeability oil and gas reservoirs. And its overseas exploration will still follow the principle of operative exploration and stress strategic selection of potential areas so as to discover more and better quality reserves.

Key words: CNOOC, oil and gas exploration, active fault belts in the Bohai Sea, high temperature and high pressure area, overseas exploration, unconventional oil and gas exploration
