Our forward-looking facility design enhances the efficiency of our operations, furthers our commitment to minimize the environmental footprint of our operations, and demonstrates our focus on our customers.

Forward-Looking Design

The Centralized Oil Stabilization Facility (COSF) in the DJ Basin and Regional Oil Treating Facilities (ROTFs) in the Delaware Basin are designed to gather and separate oil at the facility rather than at a producers’ well sites. This direct-from-wellhead pipeline infrastructure, along with other operational innovations: 

  • Eliminates the need for our customers to install separation equipment, storage tanks, and associated oil vapor recovery units at individual well sites, thus reducing cost and their environment footprint
  • Reduces up to 11,000 metric tons per year of CO2e at each producers’ production site
  • Future promotes multi-well pads by reducing equipment at the wellsite
  • Reduces fugitive emissions by piping oil directly from the wellhead to the COSF/ROTF
  • Eliminates thousands of miles in truck traffic, associated emissions and dust

Centralized Oil Stabilization Facility

First constructed in 2014, the COSF in Weld County stabilizes high-vapor-pressure crude oil received from the field through an oil-gathering system pipeline. 

The COSF includes two 250,000-barrel crude oil storage tanks and connectivity to local storage. It also has access to the White Cliffs pipeline, Saddlehorn pipeline, Tallgrass Energy’s Pony Express pipeline and rail-loading facilities in Tampa, Colorado, and local markets. 


Regional Oil Treating Facilities

In the Delaware Basin, WES operates two ROTFs in Reeves and Loving counties that provide next-generation treating. The ROTFs feature up to six 39,000 barrels/day trains, oil cooling refrigeration in the summer months, and minimal onsite storage. 

WES provides measurement at the well site, gathers unstabilized oil through our HVP gathering and treating system, and more than 10 Central Transfer Facilities throughout the basin to act as intermediate pump stations to the ROTFs. Oil treated in our Delaware Basin oil system is delivered into the Plains All-American Pipeline. 

Using our ROTF design, the typical West Texas production facility can reduce CO2e by an estimated 11 metric tons per 1,000 barrels of oil produced.
