Although there is a statistical correlation between basement earthquakes and waste water injection in north-central Oklahoma, the actual physical mechanisms for such correlation is poorly understood. We hypothesize that injection wells close to faults in the Arbuckle disposal reservoir influence the volume of water that can be injected, with sealed faults resulting in lower volumes and open fractures in larger volumes of injected fluid. To evaluate this hypothesis, we correlate simple radial pressures estimated from the well head pressures for each well with azimuthally limited fault set volumes and find that the highest correlation is related to East-West trending attribute lineaments. We find little correlation with either total density of lineaments in the seismic volume or with initial reservoir pressure.
