UNSPSC 71121618: Well drilling other general services

Includes h2s services.

UNSPSC 71121618 Well drilling other general services is a Commodity code that encompasses orphan well plugging, abandonment, and site restoration work—the primary activity now being solicited by state and local governments under this code. State and local buyers include environmental agencies managing oil and gas legacy sites, water authorities addressing abandoned production wells, and county solid waste or environmental departments handling landfill-related drilling. The Michigan Department of Environment, Great Lakes, and Energy is a standout repeat buyer, issuing four parallel direct solicitations in July 2026 for plugging 26 orphaned gas storage wells across Gratiot and Montcalm Counties—three separate contracts totaling approximately 26 wells with Davis-Bacon prevailing wage requirements and mandatory prequalification through prior RFPs. The Mississippi Oil and Gas Board and the Texas Railroad Commission also appear as repeat buyers in orphaned well remediation procurement. Beyond orphan wells, the code captures routine municipal water well drilling, pump station maintenance and rehabilitation, well abandonment at single-family residential properties, and specialized services such as landfill gas extraction well installation and aquifer storage and recovery conversions.

Geographic activity concentrates in Michigan (multiple concurrent orphan well projects), Mississippi (orphaned oil and gas wells), and Florida (water well construction, rehabilitation, and maintenance across multiple counties including Hillsborough, Seminole, Sarasota, Marion, and Brevard). Secondary activity appears in Texas (water treatment plant design and well maintenance), California (on-call well services through Eastern Municipal Water District across San Bernardino County; digester gas utilization at three regional water reclamation facilities), and scattered single-project solicitations in Illinois, Georgia, Oregon, Wisconsin, and Ohio. Representative recent opportunities include the Michigan Department of Environment, Great Lakes, and Energy orphan well plugging contracts posted July 16–29, 2026, with proposals due July 21, 2026, requiring unit pricing matrices and prequalification through prior RFPs with mandatory pre-proposal meetings (direct solicitation DS7612600000000322, DS7612600000000332, DS7612600000000352, and DS7612600000000342); the Hillsborough County Board of County Commissioners water well maintenance and repair ITB (ITB-26-00234) estimated at $688,073.00 for two years, due June 12, 2026; and the Eastern Municipal Water District on-call well and pump services RFQ (RFQ#3931) due April 23, 2026, seeking minimum two awards at $2.8 million maximum per contract over five years with prevailing wage requirements and California contractor licensing mandates.
