CNOOC opens new ultra-deep gas play in central Bohai

CNOOC made a gas discovery in ultra-deep volcanic formations in central Bohai, adjacent to the Bozhong Sag. The well reached a completed depth of 5,770 m and encountered more than 120 m of cumulative gas pay in volcanic rock.

The well tested about 800,000 cu m/d of natural gas, or roughly 28,000 mcf/d.  for the well. The company said the well opened a new play for offshore ultra-deep natural gas exploration in Bohai.
