Building new-quality productivity in petroleum engineering to boost high-quality development of the oil and gas industry.

Building new-quality productivity in petroleum engineering to boost high-quality development of the oil and gas industry.

Ensuring the supply of oil and gas resources is one of the key issues for China's energy security and also a crucial goal for the development of the petroleum engineering industry. China’s oil and gas exploration and development have entered the “deepwater and deep-layer” phase, and the newly developed oil and gas resources are predominantly characterized by low permeability and low quality, making it increasingly difficult to maintain and increase production. Natural gas development is currently in a stage marked by major exploration discoveries and rapid production growth; in the future, unconventional natural gas is expected to account for 50% of total production, and maintaining and boosting natural gas production will become increasingly challenging.
