We describe an integrated data collection effort to understand and mitigate seismicity in the Midland Basin. Step rate tests (SRT), pulse tests, log and seismic data were leveraged to determine reservoir conditions and available storage capacity for the injection target, the Ellenburger Group. As water is disposed into a finite pore space, reservoir conditions change as multiple wells compete for pore space. Spatial and temporal variations change rapidly and can increase the local risk of seismicity. As the disposal rate exceeds the disposal capacity of the formation, fractures form creating accelerated pathways for pressure to reach seismically sensitive faults. The collection of this data resulted in, what we currently believe to be, best practices in mitigating seismicity by curtailing volumes below the fracture gradient and ahead of regulation in the Ellenburger Group.
