Frequently Asked Questions

Fracturing is a means of opening the fissures in the Barnett Shale formation by the use of hydraulic pumps and fracturing fluid. Fresh water stored in frac pits is pumped in stages into the Barnett Shale formation.  Once fractures in the rock have been created, sand (like beach sand) is mixed with the fresh water and pumped into these fractures to help prevent the fracture from closing back once the hydraulic force is reduced.  By packing or filling of these fractures with sand, this will allow the formation to produce into the new drilled well bore (hole) and bring gas to surface.

A term applied to the valves and fittings assembled at the top of a well to control the flow of the gas. These valves and fittings are all pressure tested to a minimum of 5,000 psi before and after installing.

A tank battery is a group of tanks that are connected to receive produced water from a well.  A tank is normally a single- or double-steel or fiberglass vessel that can hold 200-400 barrels. The tank battery also includes some production equipment, such as gas separators which allow the produced water to be separated from the gas.  The produced water is removed from the tanks by truck, and taken to disposal facilities outside of the City.

A sudden, escape of gas and water from a drilling well when high pressure gas is encountered and efforts to prevent or to control the escape has not been successful.

A device attached immediately above the casing to control the pressure and prevent the escape of fluids from the annular space between the drill pipe and casing or shut off the hole, if no drill pipe is in the hole, should a blowout occur. These devices are pressure tested between 3,500 – 5,000 psi when installed and every two weeks afterwards.

The Fire Department handles all gas well emergencies. If there is an emergency, please call 9-1-1.

For non-emergency gas well concerns, contact the Gas Well Inspector.

The City does not handle royalties or mineral rights.  If you have any questions, you should call the operator of the gas well on or adjacent to your property.

The Texas Railroad Commission (RRC) and Texas Commission on Environmental Quality (TCEQ) department set the depths to protect our natural fresh water zones on interest in Texas. By law, the surface casing of a well must extend 20’ beyond the depth of a fresh water zone as determined by the RRC.  The surface casing is cemented back to the surface to protect these fresh water bearing zones.

Please contact the Gas Well Inspector at 817-276-4254 or [email protected] for general inquiries and concerns related to provisions of the City's drilling regulations.  For other concerns, the Railroad Commission of Texas (RRC) has jurisdiction over well permitting and inspections, and the Texas Commission on Environmental Quality (TCEQ) has jurisdiction over environmental concerns.  Please contact the Railroad Commission of Texas (RRC) at www.rrc.state.tx.us or 512-463-7288.
