There is a controversy between the Texas Railroad Commission and the US Army Corps of Engineers that is being followed closely by many Texas oil and gas attorneys and mineral owners. The Texas Railroad Commission is the state’s oil and gas regulator, and last year it bumped heads with the U.S. Army Corps of Engineers concerning whether the Corps has the authority to implement rules about where oil wells and injection wells can be drilled. The dispute surrounds the Joe Pool Lake, located in Tarrant County, Dallas County and Ellis County, and specifically whether drilling and injecting should be permitted within a certain distance of the dam.
Injection Wells Linked to Increases in Seismic Activity
There have been claims asserted in some circles that fracing or the use of injection wells to dispose of waste water has been linked to an increase in seismic activity near drill sites. The Corp recently obtained a study concerning the impact induced seismic activity could have on the structural integrity of the Joe Pool Lake dam. The study concluded that with respect to production, a 5,000-foot standoff distance — which is slightly larger than the one set by the Army Corps — had little effect on subsidence, or caving and settling, at the dam. In fact, the study did not recommend any change in the current ban area. Somehow, despite the study’s conclusions, the Army Corps is concerned that drilling within four thousand feet of the Joe Pool Lake dam or hydraulic fracturing within five miles of the dam could increase the risk of man-made earthquakes in the area, which could in turn structurally damage the dam. (There is already a drilling ban in effect within three thousand feet of the dam). The expansion of the ban area would encompass land from the cities of Grand Prairie, Arlington and Dallas.
