Project Description
The main goal of the proposed study is to predict the presence of faults that will be susceptible to movement in the presence of fluid injection. Additional goals include: 1) identify the presence of faults, 2) estimate changes to the in-situ stress field before and after fault slippage, and 3) explain pressure and stress perturbations between the storage unit and the crystalline basement (underburden). The project will test a series of integrated forward and physics-constrained, data-driven (inverse) models that includes the following: 1) use of a geologically well-characterized field site with microseismicity located within the basement rock, 2) predictions of temporal and spatial stress changes induced by injection, 3) methodology to better resolve basement faults including undetected faults, and 4) identification of mechanisms, which control and transmit pressure from the storage unit to the basement.
Project Benefits
Utilizing a diverse team of experts, this project will significantly increase understanding and mitigate the risk of induced seismicity. Development of technology that can identify characteristics of faults that are more likely to release seismic energy upon injection will reduce injection-induced geomechanical risks and ensure safe short- and long-term storage of carbon dioxide (CO2). This will directly benefit industries (e.g., carbon storage and brine disposal) and regulatory agencies that operate/oversee injection into geologic formation overlying crystalline basement rocks.
