CNOOC Limited Marks a New Era in Deepwater Gas Discovery

CNOOC Limited Makes Strides in Deepwater Natural Gas Exploration

CNOOC Limited, a leading oil and gas company, has achieved a significant milestone in ultra-deepwater natural gas exploration. Recently, they drilled a well in the ultra-deepwater Liwan 4-1 structure located in the Pearl River Mouth Basin, demonstrating remarkable capabilities in natural resource management.

Details of the Well Drilling Achievement

This groundbreaking well has shown an impressive production capacity of 430,000 cubic meters of natural gas daily. This marks a pivotal moment for exploration in ultra-deepwater carbonate formations, setting a new benchmark for industry capabilities.

Location and Depth Insights

The well is situated in the Baiyun Sag, recognized as the most hydrocarbon-rich area within the Pearl River Mouth Basin. With a staggering water depth of around 1,640 meters and a total drilled depth nearing 4,400 meters, the technical challenges overcome during this project are noteworthy.

Gas Pay Zones and Exploration Potential

Notably, the well encountered an impressive gas pay zone, approximately 650 meters in length within its horizontal section. This discovery opens up numerous opportunities for further exploration and extraction within the ultra-deepwater Globigerinid limestone formations.

Advancing Exploration Techniques and Understanding

Mr. Xu Changgui, the Chief Geologist at CNOOC Limited, emphasized the significance of this achievement. Previously, exploration initiatives primarily focused on clastic rocks in region. The success obtained from this well unveils an extensive untapped potential in carbonate rocks found in the ultra-deep regions.

Synergy with Existing Production Facilities

The new discovery is located near the existing production facilities associated with the Liwan3-1 gas field. This proximity allows for utilizing current infrastructure, enhancing the economic feasibility of developing the newly discovered natural gas reserves within the deep-water areas of the Pearl River Mouth Basin.

Future Prospects in Natural Gas Exploration

Observation shows that the advances made with this well could significantly advance the exploration and development of natural gas resources in ultra-deepwater zones. The synergies created between existing resources and newly discovered areas are expected to pave the way for an innovative and sustainable approach to natural gas extraction.

Emphasis on Sustainable Development

CNOOC Limited's commitment to responsible exploration and extraction is pivotal as they navigate the complex dynamics of environmental regulations and sustainable practices. Their efforts will not only develop energy resources but also ensure compliance with environmental standards.

Conclusion

The recent achievement by CNOOC Limited marks a transformative period for the oil and gas industry. Continual investment in exploration technologies and methods will be vital to leveraging the full potential of deepwater natural gas resources. This well drilling initiative represents a beacon of possibility for natural resource development, setting a precedent for future projects.
