Tall Oak II: Midcon System

Tall Oak Midstream II’s existing Midcon System spans eight Oklahoma counties (Major, Dewey, Custer, Alfalfa, Woods, Garfield, Woodward and Blaine) and includes the following assets:

  • Approximately 750+ miles of low- and high-pressure gas gathering lines,
  • 60 MMscf/d of processing capacity and 10,000 bbls/d of condensate stabilization capacity at the Carmen Cryogenic Plant, and
  • The Eagle Chief Gas Processing Plant, which includes a 30 MMscf/d refrigeration plant.

Tall Oak II has initiated the installation of a new, state-of-the-art 200 MMscf/d RSV cryogenic processing train at the Carmen Processing Facility to bring its total processing capacity in the STACK to 260 MMscf/d. In addition, Tall Oak II currently has two compressor stations and multiple pipelines under construction, with two additional compressor stations and an additional 100 miles of new, all-steel gathering pipelines planned for 2019. The buildout of the system will ultimately span more than nine Oklahoma counties and include more than 1,000 miles of gathering pipelines.

The Carmen plant serves expanding natural gas production in the liquids-rich NW STACK play which includes the Meramec zone, the Osage zone and portions of the Cana Woodford shale play. Compression is provided at six existing compressor stations located throughout Woods, Major and Dewey counties.

Tall Oak III: Arkoma STACK System

Tall Oak Midstream III has completed more than 150 miles of low-pressure and high-pressure pipelines in the Arkoma STACK as well as three compressor stations capable of compressing over 140 MMscf/d of low-pressure natural gas. The Panther Creek Plant, a 200 MMscf/d RSV technology processing plant, was completed in August 2019 and is currently moving processed gas to MarkWest’s Arkoma Connector and the NGLs are connected to OneOK’s NGL system.

The company is currently adding compression capacity and additional gathering pipelines as producers continue to add new wells to the system. The gas gathering system is currently located in McIntosh, Okfuskee, Hughes and Coal counties with plans to expand into Pittsburg, Okmulgee and Seminole counties as future drilling occurs.
