my country has discovered the world's first ultra-deep water and ultra-shallow large gas field

Up to now, CNOOC’s proven natural gas geological reserves in three basins including Qiongdongnan and Pearl River Estuary have accumulated more than 1 trillion cubic meters.

"To ensure the safety of offshore drilling operations, the industry generally avoids crossing dangerous shallow gas layers when designing well locations. We are rising to the challenge this time." CNOOC Hainan Branch Introduction to relevant personnel of the Engineering Technology Operation Center. After rigorous technical demonstration, CNOOC carried out the world's first ultra-deep water and ultra-shallow drilling operation, successfully completed many goals such as drilling and testing of ultra-deep water and ultra-shallow gas reservoirs, obtained relevant regional stratigraphic data with high quality, and accurately outlined the large gas fields. A comprehensive underground picture is provided to achieve accurate and rapid evaluation of the world's first ultra-deep water and ultra-shallow gas field.

The exploration practice of Lingshui 36-1 has verified that ultra-deep water and ultra-shallow gas resources have been transformed from "disaster gas" that affects the safety of drilling and completion operations into clean energy with development value. The possibility has guiding significance for resource exploration and development in similar sea areas in my country and even the world, and will help improve my country’s independently established deepwater complex oil and gas resource exploration and development technology system with Chinese characteristics.
