Topic: Research Progress on Wellbore Cementing and Wellbore Integrity

Introduction: Cementing is an important step during the construction of oil and gas wells and its primary function is to provide proper sealing of the annulus space between the casing and the formation. Nowadays, with continued development of deep oil and gas resources, wellbore drilling and completion depths continue to increase and wellbore conditions become increasingly complex; additionally, more and more unconventional well are constructed for geothermal energy development and storage of carbon dioxide, hydrogen, or other gases. These new changes in the industry presents significant challenges for cementing operations and wellbore integrity. This special session welcomes submissions on the latest research advances related to cementing operations and wellbore integrity. This includes, but is not limited to, studies on the performance characterization of cementing systems under harsh downhole conditions such as high temperature, high pressure, corrosive fluids, and complex loading conditions, as well as related research outcomes in numerical simulation and optimization.

Yongjin Yu
CNPC Engineering Technology R&D Company Limited, China

Biography: Dr. Yongjin Yu is the Chief Corporate Expert at the China National Petroleum Corporation (CNPC). His research primarily focuses on cementing technology for complex oil and gas wells. he has led the development of over 20 specialized cementing admixtures and cementing fluid systems, including cementing slurries and spacers that are resistant to ultrahigh temperatures (240°C) and suitable for extra-long wellbore sections with large temperature differentials. These systems have been widely adopted in field applications, effectively supporting high-quality cementing operations for key wells drilled by CNPC.
