Multi-Site Midstream Tie In Project
Oil & Gas | Midstream
Location | New Mexico
The Challenge
The client required a comprehensive engineering and design solution for a complex, multi-site pipeline tie-in project involving several interconnected valve and meter sites. The project demanded precise coordination across multiple facilities, including integration of new and existing pipeline segments of varying diameters, materials, and configurations. In addition to the technical challenges of managing several tie-in points and underground transitions, the project scope also included multiple horizontal directional drills (HDDs) for road crossings, all of which needed to comply with the client’s strict design and construction standards.
The Solution
Halker assembled a multidisciplinary team of engineers and designers to deliver complete engineering and design services for the multi-site tie-in program. The team developed detailed solutions for multiple interconnected sites, including the design of a new 4-way valve site where an existing 16-inch ball valve was tied into a 16-inch CV 1-3 line using a below-ground carbon steel and HDPE transition. Additional scope included 20-inch SDR 13.5 and dual 8-inch poly hot taps with ball valves to support future tie-ins.
For another site, Halker engineered a custom 16-inch meter header equipped with a 4-inch sales meter, overpressure protection, and provisions for two future 4-inch connections. This system was tied into an existing 12-inch ball valve and connected downstream to a new 3-way site through a combination of 20-inch SDR 13.5 piping, barred tees, and 12-inch transitions. At an adjacent location, the team designed an 8-inch meter header with a 4-inch sales meter and overpressure protection, along with two 4-inch future connections and an 8-inch isolation valve to enhance operational flexibility.
The project also required design support for four county road crossings, each completed via HDD. Halker provided HDD calculations, crossing drawings, and construction details to ensure safe installation and minimal surface disruption. Deliverables included P&IDs, piping plans and isometrics, foundation and support plans, electrical hazardous area drawings, and full construction scopes for each site. The team also provided hydrotest support and final as-built documentation, ensuring all work met the client’s standards for quality, safety, and regulatory compliance.
Through detailed coordination and disciplined execution, Halker delivered a fully integrated and constructible design package, enabling the client to safely and efficiently expand their midstream infrastructure while maintaining continuity of operations across multiple tie-in sites.
