The Hub
Weld County, Colorado
Client/Owner: Crestone Peak Resources (formerly Encana)
In an effort to reduce the impact of its activity on a nearby community, Crestone Peak Resources continues on Encana’s plan to utilize a centralized gathering facility in the Denver–Julesburg Basin (DJ Basin). Known as the Hub, this central gathering facility is located just east of Erie, Colorado in Weld County, the heart of the DJ Basin. The Hub allows for most of the collection and processing equipment to be in one central location; specifically, a liquids processing area to further separate the water from the oil, stabilize the oil, and capture the rich vapor. This reduces a typical Pad size by about 70 percent, from approximately 5 acres down to 1.5 acres, eliminating in-town truck traffic, and greatly reducing the overall amount of dust and noise associated with construction and operations.
Reveille Natural Gas Processing Plant
Webb County, Texas
Client: Alpine Site Services
Owner: Howard Energy Partners
This project included the construction of a new natural gas processing facility on approximately 12.5 acres of vacant land in the heart of the Eagle Ford Shale complex. This mid-stream plant processes 200 million cubic feet per day, separating out the natural gas liquids, or NGLs, from incoming natural gas pipelines, enabling them to meet downstream specifications as well as obtain greater value for their liquids production including ethane, propane, butane and natural gasoline.
The CG team provided geotechnical engineering services prior to site development. Prior to our site investigation, earthwork included significant cut and fill depths (up to about 16 feet) with little or no geotechnical oversight. This, combined with expansive soils presented unique challenges for support of equipment loads up to about 200,000 pounds, including separators, slug catchers, cryo units, compressors and pumps, storage tanks, and other skid-mounted equipment as well as a flare and pipe rack assemblies. As a result, we included recommendations for the use of helical piles. Our client proposed the use of 5-1/2, 7, and 9-5/8 inch diameter piles to support complicated load combinations. Load testing was completed under our supervision to determine the compressive, tension, and lateral load capacity of each pile type and provide minimum installation criteria for construction.
