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.
