Major Oil Discovery Made in China's Bohai Bay Basin

摘要

A game-changing discovery has been made in China with the successful completion and production of terrestrial shale reservoirs, which have maintained a natural flow for more than 260 days. This success ushers in a new era for China's successful development of its complicated, deep, lacustrine-origin shales. As of Feb. 27, two horizontal wells, the Guandong-1701H and Guandong-1702H wells have produced shale oil for more than 260 days by natural flow from the continental shale formation of the second member of the Paleogene Kongdian Formation in the Guandong area in the eastern Bohai Bay Basin, eastern China, with a stable daily oil production of 145 barrels and 220 barrels, respectively, and a cumulative oil production of more than 73,500 barrels. The shale oil production in the Guandong area with an estimated reserve of more than 735 million barrels marks the start of the commercial development of continental shale oil by PetroChina in the Bohai Bay Basin.
