The Permian Basin is one of the prolific hydrocarbon-producing regions in the world, containing numerous vertically stacked producing intervals. Off late, operators are moving into “factory/tank”-style field development strategy to optimize production. However, the geology presents some unique challenges ranging from rapidly changing geology, presence of thin-bed, to variable pore pressure gradient. Failing to address these challenges may lead to significant uncertainties in petrophysical evaluation, well interference and ultimately impacting producibility. High-performance computing and advanced analytical techniques permit operators building high-quality geomodel via integrating field measurement, seismic and sonic data, and core measurement. The quality of core based geomechanics and petrophysical measurement is not only crucial for success of modeling effort but also for better understanding of the hydraulic fracturing process, fluid flow behavior, well and stage placement and landing target identification. This talk highlights some key core-based measurements to understand permeability and its variation with stress, mechanical and poroelastic behavior of rock and variability of insitu horizontal stress.
We begin with introducing technique for measurements of matrix and fracture permeability. We present results on samples obtained from Permian and other producing reservoir and how they are impacted by fabric and composition. We also present a recently developed method to clean the plug to obtain the absolute matrix permeability. Following this, we briefly touch upon static and dynamic mechanical property measurement that honors reservoir heterogeneity and anisotropy. We then demonstrate how the measurements can be scaled up to build a well-centric geomodel including insitu stress profile. Finally, we identify the importance of poroelasticity in hydraulic fracture design and present a laboratory technique for measurement of poroelastic coefficient. We conclude with presenting an example of well-centric geomodel building for the region.
Abhijit Mitra is currently with MetaRock Laboratories as a Geomechanics Consultant. Previously, he was with Schlumberger and New England Research. He has more than nine years of experience in upstream oil and gas industry and his area of expertise includes experimental geomechanics and flow through porous media. He published several articles in peer-reviewed journals and conferences and taught geomechanics short-courses at American Rock Mechanics Association and SPWLA annual conferences. He also chaired technical sessions at URTec and American Rock Mechanics Association annual conferences and reviewed manuscripts for these conferences as well as for SPE Journal and Journal of Natural Gas Science and Engineering. He also serves as webmaster for SPE Geomechanics Technical Section. He received BS and MS in Mining Engineering from India and PhD in Engineering Science from Southern Illinois University.
