About
Shiji Fang is a leading researcher in downhole robotics for oil and gas drilling, with a focus on coiled tubing (CT) operations in horizontal wells. His work addresses the critical challenge of tool transportation and control in high-temperature, high-pressure (HTHP) environments. Fang’s major contributions include pioneering the combined control of weight on bit (WOB) and rate of penetration (ROP) using an electric downhole robot, a breakthrough that enhances drilling efficiency and precision. He also advanced the understanding of dynamic sealing performance through a novel HTHP coupling method, moving beyond traditional separate loading analyses to more accurately evaluate seal integrity under real-world conditions. His research on axial-torsional dynamics, based on fluid-structure interaction models, further deepens the knowledge of robot behavior during drilling. With over 30 citations across his most-cited works, including a 2021 paper with 16 citations, Fang’s studies are foundational for the development of traction robots that mitigate CT buckling and locking. His 2023 review on traction robot trends and 2025 mechanical modeling of anchoring mechanisms underscore his ongoing influence, making him a key figure in advancing autonomous downhole drilling technologies.
