Johnson County Injection Well Data
The following well and reservoir testing data was requested by the Railroad Commission of Texas from four disposal well operators in Johnson County on May 8, 2015 following an estimated 4.0 magnitude earthquake in North Texas. The data was requested for the Railroad Commission of Texas to examine and share with academic researchers conducting studies to assist in understanding whether or not oil and gas operations may be related to recent seismic activity observed in area. The data is from five wells that are within 100 square miles of the estimated seismic activity epicenter.
Microsoft Excel and Word files including injection pressures and volumes for the specific injection wells organized by date. Some files include embedded graphics and others do not.

Injection Well Data
Bosque Disposal Systems, LLC
The following analysis provided by Bosque Disposal Systems, LLC: Monitoring of the injection pressures began at 6:00 a.m. and the Pressure Fall Off Test was initiated at 9:00 a.m. The initial injection pressure recorded was 1697 psi. Upon stopping injection and shutting the well in, the pressure immediately dropped to 625 psi. The well dropped in pressure until 3:20 p.m. At 3:20 p.m. the well stabilized at 340 psi. The pressure held until 4:05 p.m. At 4:05 p.m., injection began again at an initial rate of 1585 psi. At 5:00 p.m., the injection pressure stabilized at 1695 psi.
