Title:Complex process feedbacks related to energy recovery and the sequestration of energy wastes
Seminar:Seminar on Mathematics in the Bio and Geo Sciences
Speaker:Derek Elsworth, Dept of Energy & Mineral Engineering, Penn State
Abstract:
Fluids in the shallow crust of the earth exert important controls on a wide spectrum of natural and engineered phenomena. The complex interaction of stress and particularly that of chemistry exhibit important feedbacks which influence the evolution of the mechanical and transport properties of rocks. These feedbacks in turn relate crucially to the subsurface recovery of hydrocarbons, from the full spectrum of conventional through unconventional reservoirs to the recovery of hydrothermal and non-hydrothermal geothermal resources, to the secure and enduring sequestration of energy by-products including CO2 and radioactive wastes, and also to the earthquake cycle, for example. Enigmatic interactions between stress and chemistry in mediating the evolution of permeability and strength in natural and engineered systems are explored – as relevant to high-carbon through low-carbon economies. Examples are selected to illustrate the significance of these interactions in controlling the response of hydrocarbon and geothermal reservoirs, fracture treatments, radioactive waste disposal and in the response of faults.
