Abstract

Crosswell seismic (CS) technology provides a high-resolution image of the subsurface between two nearby wells. Crosswell seismic data can reach frequencies greater than 1000 Hz, which makes the technology applicable to many reservoir-development challenges in hydrocarbon exploration and production studies that require high resolution. Applications of crosswell seismic data range from structural and stratigraphic interpretation to reservoir monitoring and enhanced oil recovery (EOR). When integrated with rock physics, crosswell seismic data can be used in reservoir-characterization studies, which potentially could be used for enhancing the resolution of rock properties derived from 3D surface-seismic data to that of crosswell resolution. In addition, velocity models obtained from crosswell seismic data can be used to better predict event locations in microseismic data processing.
