Vaquero Midstream commissions Delaware basin gas plant

Vaquero Midstream LLC, The Woodlands, Tex., has commissioned its Caymus I natural gas processing plant in Pecos County, Tex., in the southern Delaware basin.

Supported by long-term commitments with major producers in the area, the Caymus 1 development consists of a UOP Russell 200-MMcfd cryogenic processing plant on 330 acres to enable expansions of as many as four additional 200-MMcfd trains for accommodating future production growth in the region, Vaquero Midstream said.

Alongside connection to a Vaquero-owned and dedicated electrical substation that will ensure uninterrupted power service to the facility, the Caymus 1 plant is equipped with the following features:

• Oversized inlet-liquids handling with 5,000 b/d of condensate stabilization and storage.

• Inlet compression to minimize field pressure.

• Amine treating.

• Propane refrigeration prior to cryogenic processing.

• Energy Transfer Technologies Ltd.’s proprietary Dual-Drive residue compression.

Given its configuration, Caymus 1 has flexibility to handle future production from Avalon, Wolfcamp, and Bone Spring shale formations, the operator said.


The plant receives feed gas via an 80-mile, 800-MMcfd, high-pressure gathering pipeline system directly connecting to Pecos, Reeves, Ward, and Culberson counties, while a residue header connects multiple outlets at the WAHA market, including connections with Atmos, Enterprise, Northern Natural Gas, and Oneok’s WestTex Transmission system, the latter of which connects to the Roadrunner gas transmission pipeline.

These four connections allow processed volumes from Caymus 1 access to more than 12 residue gas outlets in the US Midwest, US Gulf Coast, as well as California and Mexico.

Vaquero’s NGL header line additionally includes outlets connecting to Lone Star’s West Texas Gateway pipeline and Enterprise Chaparral systems, the company said.
