Topic: Rock Mechanics and its Application to Petroleum Engineering
Speaker: Ohmyoung Kwon
Bio: Dr. Ohmyoung Kwon is the manager of Rock Mechanics Lab of OMNI Laboratories (Weatherford Laboratories) in Houston, TX. He has earned a Ph.D. in Geology and Geophysics from Texas A&M University’s Center for Tectonophysics investigating the mechanical and flow properties of clay-rich shales in addition to an M.S. degree in Geosciences from The University of Texas at Dallas. He has worked as a research fellow at The University of Edinburgh, Scotland investigating the effect of deformation on fluid flow. Dr. Kwon also worked as a post-doctoral research scientist at Texas A&M University. Ohmyoung has over fifteen years of experience in geomechanics and rock physics analyzing and investigating static and dynamic mechanical properties and fluid-flow properties of reservoir and cap rocks with applications to petroleum-related rock mechanics. Ohmyoung has extensive experience on conventional and unconventional cores developing test programs and providing engineering analysis services.
Abstract: Mechanical properties of reservoir rocks are widely used for many engineering and geophysical applications in the oil and gas industry. Rock mechanics essentially affects every aspect of petroleum engineering including well planning, drill bit selection, drilling, completion and production. Sonic or dipole sonic logs are widely used to determine the mechanical properties of the reservoir rocks. However, the mechanical properties derived from the sonic log (i.e., dynamic elastic properties) are indirect method and dynamic moduli are almost always higher than the static moduli measured in the lab based on the stress-strain relationship from triaxial compressive strength tests. For engineering applications, the static mechanical properties conducted at simulated in-situ stress condition or dynamic mechanical properties calibrated to the static properties should be used and core measurements for both static and dynamic properties are recommended to establish relationships between the two properties that are specific to the reservoir or field under development. Since the rock mechanics plays an important role even at the initial stage of field development, it is important to have rock mechanics testing done as early as possible. The Rock Mechanics Lab at OMNI Laboratories provides core-based testing and engineering analysis services to optimize reservoirs and enhance production. The core-based rock mechanics data and engineering analyses can be used to solve costly problems in drilling, completion and production. A variety of rock mechanics testing will be reviewed with its applications to the practical problems in petroleum engineering and geophysics, such as hydraulic fracture design, wellbore stability, sand production, reservoir compaction, fracture azimuth, dipole sonic log calibration and 4-D seismic.
