The overall objective of the project was to study the seismic effects of fluid withdrawal from deep reservoirs and its subsequent reinjection closer to the surface. This effort included the design and installation of a hardware system and development of a study approach to monitor dynamic deformation in the Gulf Coast environment. Over the long term, insight gained into the ground deformation process (specifically ground subsidence) may potentially allow the integration of observations of individual phenomena into predictive tools for future use in ground subsidence studies. The value of a seismic monitoring network as a predictive tool can only be evaluated by an integrated program to study ground and instrument performance with time. Integrating extended real time monitoring of potential seismic precursors to significant displacements may represent the first integrated study of subsidence undertaken in the Gulf Coast region.
