my country's first 100-meter water depth oil and gas in-situ expansion platform goes into operation

Reporters learned from CNOOC today (9th) that as the first expansion adjustment well of the Enping 24-2 oil field was successfully put into production, my country's first 100-meter water depth oil and gas in-situ expansion platform was officially put into use, opening up a new path for tapping the potential and increasing efficiency of old offshore oil fields.

The in-situ expansion platform of the Enping 24-2 oil field, which was put into operation this time, is located in the waters of the Pearl River Mouth Basin about 200 kilometers southwest of Shenzhen, with an operating water depth of nearly 100 meters. The project adopts the innovative model of "installing new modules in situ on old platforms". Without stopping production or reconstructing the original production system, a new operating platform is accurately installed, adding 12 well slots and deploying 16 adjustment wells, effectively breaking the development bottleneck of saturated well locations and limited production capacity on the original platform.

As the main producing oil field in the core of the Pearl River Mouth Basin, Enping 24-2 Oilfield has produced more than 12 million tons of crude oil since it was put into production in October 2014. After more than ten years of continuous development, the oil field's original production platform operating space and drilling well locations have been completely saturated, and a large amount of remaining oil and gas reserves cannot be effectively utilized.

In recent years, my country's offshore oil and gas development has insisted on advancing the new and the old simultaneously. While promoting the construction of new projects, it has accelerated the transformation to improve the quality and efficiency of existing oil fields. Tapping the potential and increasing efficiency of old oil fields has become an important support for stable offshore oil and gas production. The successful implementation of the 100-meter water depth level in-situ expansion technology has further improved my country's deepwater oil and gas development technology system, and has important demonstration significance in consolidating the foundation for stable offshore oil and gas production and improving domestic energy independent guarantee capabilities.
