UNSPSC 71161102: Enhanced oil recovery services

Evaluation or design services to restore formation pressure and to improve oil displacement or fluid flow in the reservoir.

UNSPSC 71161102 Enhanced oil recovery services is a Commodity code that, based on recent state and local solicitations, encompasses landfill gas collection, extraction, and utilization infrastructure—not traditional petroleum recovery. State and local governments are buying the design, construction, and installation of landfill gas capture systems, including extraction wells, perforated collectors, lateral piping, condensate handling, and gas-to-energy conversion facilities. The issuing bodies include special-purpose districts focused on solid waste management and water reclamation. The Dalton-Whitfield Solid Waste Authority in Georgia is actively procuring landfill gas infrastructure expansion, while the Eastern Municipal Water District in Riverside County, California is seeking a Design-Build-Finance-Own-Operate-Maintain partner for digester gas utilization at three regional water reclamation facilities. Both solicitations signal ongoing demand for gas capture and renewable energy infrastructure tied to waste and wastewater treatment operations.

Recent opportunities cluster in the Southeast and California. 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 (response deadline May 21, 2026), requiring Georgia-licensed general contractors with a minimum of five years' landfill gas system experience and five completed similar projects. The Eastern Municipal Water District issued a Request for Proposal (RFP) on February 24, 2026, for a long-term digester gas utilization project (response deadline April 14, 2026), targeting proposers with five years of direct DBFOOM digester gas project experience, requiring performance and payment bonds estimated at approximately $20 million, $2 million, and $2 million respectively, with contract terms of 15 or 20 years plus optional extensions and substantial completion by June 2029. Both opportunities require demonstrated technical capability in gas extraction and handling, insurance and bonding thresholds scaled to project scope, and compliance with air quality and operational standards.
