The Railroad Fee (RRC) of Texas has issued new laws on allowing disposal wells within the Permian Basin. The Fee stated in a media launch that the rules had been based mostly on scientific and engineering evaluation.
To enhance the integrity of underground produced water disposal, new laws will probably be launched for saltwater disposal nicely (SWD) allow functions within the space. Produced water, a byproduct of oil and gasoline extraction, is injected into SWDs.
The fee added that new and amended allow functions within the Permian Basin will probably be evaluated based mostly on an expanded space of overview (AOR) on the injection web site, limits on the utmost injection strain on the floor based mostly on geologic properties, and limits on the utmost each day injection quantity based mostly on reservoir strain.

In an AOR, operators should consider deserted or inactive wells to guarantee that produced water doesn’t leak by way of these wellbores, the Fee stated. The up to date pointers prolong the AOR to half a mile, from the present quarter-mile radius.
The up to date allowing requirements additionally necessitate that operators show their injection strain is not going to break the confining layers of the reservoirs into which the produced water is injected. The Fee additionally added that it’ll impose restrictions on the utmost quantities that SWDs can inject, relying on the strain inside the disposal reservoirs.
These modifications improve the Fee’s allowing necessities for disposal wells by concentrating allowing efforts on making certain that injected fluids keep contained inside the disposal formations, thereby defending floor and floor freshwater, it stated.
The RRC stated the up to date SWD allowing requirements within the Permian Basin will probably be efficient beginning June 1. These requirements apply to new and modified allow functions for deep and shallow disposal wells. Allow functions for disposal wells located inside 25 kilometers (15.5 miles) of a seismic occasion will nonetheless be assessed in accordance with the company’s seismicity overview protocols, it stated.
