The poromechanics of shale
Speaker
Ronaldo Borja, Stanford University
Abstract
Shale is a clastic sedimentary rock consisting of softer materials such as clay and organics, stiffer minerals such as quartz, feldspar, and pyrite, and void spaces that can range in size from nanometers to millimeters. It is the most common sedimentary rock on Earth, accounting for approximately 75% of rock in sedimentary basins. My talk will explore the mechanical and hydraulic properties of this material that could have some important implications for hydrocarbon extraction and carbon sequestration. Of particular interest are the impacts of fluids in the pore spaces on the evolution of the stiffness, strength, and fluid conductivity properties of this geologic material.
Biography
Ronaldo Borja works in theoretical and computational geomechanics, geotechnical engineering, and geosciences. His research includes the development of mathematical and computational frameworks for multiscale and multi-physical processes in geomechanics and related fields. He is the author of a textbook entitled Plasticity Modeling and Computation published by Springer and serves as executive editor of two journals in his field: the International Journal for Numerical and Analytical Methods in Geomechanics and Acta Geotechnica. Ronaldo Borja is the recipient of the 2016 ASCE Maurice A. Biot Medal for his work in computational poromechanics.
