In recent years, the proportion of low-permeability, low-pressure, and low-productivity oil and gas wells in China’s oilfields has been increasing year by year. As a key production mode for such wells, intermittent production plays an important role in stabilizing production, reducing energy consumption, and protecting reservoirs. However, the traditional manual intermitte... Read more.

Well completion is the process of creating an effective flow path between the reservoir and the wellbore. An effective completion must maintain the mechanical integrity of the wellbore while ensuring fluid flow within the well. This paper outlines a method for optimizing horizontal well design, using a skin factor mod... Read more.

Ultra-deep well drilling in the Zhebachang Structure and Suining-Santai Qixia Formation Slope Structural Belt of northwestern Sichuan is confronted with a harsh environment characterized by high temperature, high pressure, and high stress. The geological conditions are complex, variable, and difficult to pred... Read more.

Small leaks in pipeline systems, though less dramatic than major ruptures, pose significant long-term threats to safety, environmental health, and operational efficiency. Early detection is critical, and various online (real-time) detection techniques have been developed to address this challenge. This paper presents a comparative study of three major classes of online leak ... Read more.
