SEISMIC EMISSION TOMOGRAPHY-1: Seismic used to directly map reservoir permeability fields

This two-part article summarizes a series of tests indicating that a technology now exists for near real-time 3D mapping of the reservoir-scale permeability field using surface-based seismic acquisition networks.Despite decades of work, hydrocarbon production, particularly that of oil, remains highly inefficient with often up to 60-70% of the known resource being left unproduced. It is generally acknowledged that the principal obstacle to more efficient production is the absence of a means of accurately mapping the reservoir “architecture” or permeability field.Our work, combining a new geomechanical model for the behavior of fluids in the earth’s brittle crust in combin...
