Biography
Olivier Stab is a researcher whose work focuses primarily on the analysis and optimization of drilling tools, particularly in the area of interactions between drill bits and rock formations. His research focuses on developing advanced 3D models to study drilling dynamics, incorporating computer vision and deep learning techniques. These methods enable the extraction of precise geometric data from videos captured in the field, thereby facilitating the assessment of bit wear and the improvement of their design. His work also includes simulating damage scenarios for cutting tools, with the aim of optimizing the durability and performance of drill bits under real-world conditions, particularly in complex environments such as the oil fields of the Middle East or North American shale formations. In addition, Olivier Stab has contributed to studies in fluvial geomorphology and hydrogeological modeling, exploring the dynamics of erosion, sedimentation, and the reorganization of river systems on geological time scales.
