Industry Brief

A 10-inch diameter natural gas gathering pipeline owned by Copano Energy LLC ruptured several miles north of Alice, TX, Thursday afternoon. There were no injuries or damage to property in the rural area except for a small grass fire, Copano spokesman Craig Brown told NGI. The pipeline was moving less than 5,000 Mcf/d of gas at the time at less than 500 psi operating pressure. A small amount of production from the field being served by the line is shut in. An investigation is to be conducted into the cause of the explosion, Brown said. Alice is 239 miles southwest of Houston.
