A binding open season began Feb. 9 for long-term commitments on the third major expansion of Medallion Pipeline Co. LLC’s 320-mile crude oil pipeline system, the company said Feb. 10.

Firm transportation capacity can be acquired under minimum 10-year term agreements on the Howard Lateral and the Wolfcamp Connector expansion. Full commercial operations will begin in the second quarter of 2016, but certain segments could go into service earlier on an interim basis, Medallion said.

The 45,000 (Mbbl/d) bidirectional Howard Lateral would take crude oil from multiple origin points in Howard County, Texas, about 49 miles to the southeast to a new point of interconnection on Medallion’s Wolfcamp Connector mainline system in Glasscock County, Texas.

A total of 30 Mbbl/d could be added to the Wolfcamp Connector, which originates at the Garden City Station in Glasscock County and extends about 60 miles north to the Colorado City hub in Scurry County, Texas.

The open season ends Feb. 26.

Medallion Midstream LLC is based in Irving, Texas.
