Project Description

Downhole seismic sources can be used as part of a seismic monitoring effort to track CO2 plumes during carbon storage activities. This project is developing and field validating low-cost, automated borehole seismic source systems (Figure 1). Current downhole seismic systems are expensive and have reliability issues that this effort is addressing by developing two types of orbital vibrator downhole seismic sources: one for high-resolution cross-well surveys, and one for high-resolution vertical-seismic-profile surveys. Both types of sources are being designed for permanent installation, will be capable of providing continuous active source monitoring, and will be used to improve CO2 monitoring in the subsurface. Prototypes for each unit are being performance tested/verified at the Lawrence Berkeley National Laboratory’s Geoscience Measurement Facility and at the Richmond Field Station.

Project Benefits

The benefits associated with this effort include the ability to acquire reliable, real-time measurements of injected CO2, track and quantify uncertainty of spatial and temporal movement of the CO2 plume through the storage reservoir, define the lateral extent and boundaries of the plume, and demonstrate long-term stability of the CO2 plume. This effort is contributing to the U.S. Department of Energy (DOE) Carbon Storage Program’s goal of ensuring 99 percent storage permanence and containment effectiveness.
