Southcross Energy will provide natural gas-gathering, transportation and processing services to Swift Energy for production at its acreage in McMullen County, Texas, US.

As part of the agreement, Southcross will construct a 25 mile-long, 20in-diameter natural gas pipeline along with related lateral gathering lines.

To gather gas from the acreage for processing, Southcross will convert an existing dry pipeline system to rich gas service.

Initially, the McMullen extension will have an expandable capacity of 120 million cubic feet of natural gas per day and is expected to come into service in mid-2011.

The pipeline will begin from McMullen County and extend to Southcross’s CCNG Transmission pipeline for gas delivery to its processing plant near Gregory, Texas.
