Phase one of China's first 100-billion-cubic-meter gas field in the Bohai Sea has entered full operation, with daily oil and gas output exceeding 5,200 tons, said the China National Offshore Oil Corporation (CNOOC) on Sunday.
Located in the central Bohai Sea, the Bozhong 19-6 gas field holds proven natural gas reserves of over 200 billion cubic meters and proven oil reserves exceeding 200 million cubic meters.
Buried at depths of more than 5,000 meters, the field features a wide distribution range and complex reservoir types, making its development challenging.
"Facing formations with temperatures reaching up to 204 degrees Celsius and hardness exceeding that of conventional carbon steel, we have established a self-developed drilling and completion technology system tailored to the deep formations of the Bohai Sea. In Phase I, we successfully drilled 10 ultra-deep wells exceeding 6,000 meters, and the average depth of wells in the phase surpasses 5,500 meters," said Zhu Guowei, a drilling manager at the industrial technology center of CNOOC Tianjin Branch.
As the largest offshore gas field in eastern China, the field has cumulatively produced more than 2.8 billion cubic meters of natural gas, playing a pivotal role in ensuring stable supply for the Beijing-Tianjin-Hebei region and the Bohai Rim region.
"We implement tailored management strategies for each gas well. The field currently produces 3.5 million cubic meters of natural gas per day, and we are making every effort to meet the energy needs of surrounding areas during the summer peak season," said Jiang An, general manager of an operating company under CNOOC Tianjin Branch.
Drilling operations for phase two of the Bozhong 19-6 gas field are underway, aimed at strengthening the role of offshore oil and gas in supporting China's domestic energy supply.
