UNSPSC 71161402: Well completion engineering services

Evaluation and design or testing of the assembly of downhole tubulars and equipment required to enable safe and efficient production from an oil or gas well.

UNSPSC 71161402 Well completion engineering services is a Commodity code that captures landfill gas and digester gas extraction system infrastructure work being solicited by regional waste and water authorities. State and local governments procure under this code for the design, installation, and commissioning of gas extraction wells, piping networks, condensate management systems, and associated monitoring and control equipment at solid waste and wastewater treatment facilities. The issuing bodies are typically special-purpose districts and regional authorities responsible for waste management and water reclamation — the Dalton-Whitfield Solid Waste Authority in Georgia and the Eastern Municipal Water District in California — rather than general-purpose county or city governments. Work scopes involve comprehensive extraction system infrastructure including surveyed well locations, HDPE-cased extraction wells, perforated horizontal collectors, lateral piping in multiple diameters, liquid conveyance lines, air supply lines, wellheads, condensate sumps, isolation valves, and operational controls and monitoring equipment, with performance timelines typically in the range of 120 to 150 calendar days for construction and substantially longer (to 2029 or beyond) for design-build-operate contracts.

The code shows recent activity concentrated in the Southeast and Southwest. The Dalton-Whitfield Solid Waste Authority issued an Invitation to Bid (ITB) on April 17, 2026, for landfill gas collection and control system expansion at its Old Dixie Highway Municipal Solid Waste Landfill in Dalton, Georgia, with a bid deadline of May 21, 2026, and a mandatory pre-proposal conference on May 1, 2026; the procurement requires Georgia-licensed general contractors with minimum five years' experience in similar projects and 50 percent on-site labor, with liquidated damages escalating from $2,000 to $5,000 per day. The Eastern Municipal Water District in Riverside County, California, issued a Request for Proposal on February 24, 2026, for a long-term Design-Build-Finance-Own-Operate-Maintain agreement to convert digester gas to renewable natural gas at three Regional Water Reclamation Facilities, with a proposal deadline of April 13, 2026, mandatory pre-proposal and site tour dates in March 2026, and contract terms of 15 or 20 years with optional 5-year extensions; the RFP requires five years of direct experience in similar digester gas projects and carries estimated bonding requirements of $20 million for bid, $2 million for payment, and $2 million for performance bonds.
