Plains All American Pipeline LP is testing support in a potential 350,000 b/d project to carry crude oil from the Permian Basin to its terminal in Cushing, OK.

The Houston-based master limited partnership (MLP) said Tuesday a subsidiary would hold an open season for the proposed pipeline until noon on May 30.

The MLP said it is looking to secure long-term commitments for firm transportation on the pipeline, with origin points in Midland and Colorado City, TX. New volumes committed through the open season would move on a combination of new and existing pipes depending on the results, the MLP said.

Assuming it secures enough commitments and receives regulatory approvals, Plains said it could have the project up and running by mid-2019.

Plains has been making moves recently to expand its midstream footprint in the prolific Permian.

In January, Plains paid $1.215 billion for a major crude oil gathering system in the northern Delaware sub-basin that serves “several producers” in the play. A few weeks later, Plains formed a joint venture with Noble Midstream Partners LP to purchase Advantage Pipeline LLC for $133 million, adding an expandable 70-mile, 16-inch diameter crude oil pipeline system in the southern Delaware.

Plains said parties interested in the proposed Permian-to-Cushing project should contact Managing Director of Pipeline Commercial Operations Bill Keener at (713) 993-5144.
