These two plants will have the ability to produce approximately 25,000 barrels per day of raw natural gas liquids.

The 78-mile pipeline extension will transport raw natural gas liquids (NGL) from a natural gas processing plant being built by Devon Energy in Hughes County, Oklahoma, and a recently constructed natural gas processing plant owned by Antero Resources Midstream in Coal County, Oklahoma.

The $25 million extension of the pipeline is scheduled for completion in the second quarter of 2008.

Terry Spencer, executive vice president of ONEOK Partners’s natural gas liquids business, said: When we complete our Arbuckle pipeline in early 2009, we will be able to transport these additional NGL barrels to our Mont Belvieu, Texas, fractionation facility.
