UNSPSC 71131101: Acid based matrix stimulation services

Services for the treatment of a reservoir formation with a stimulation fluid containing a reactive acid.

UNSPSC 71131101 Acid based matrix stimulation services is a Commodity code that shows minimal recent alignment with state and local procurement activity. The recent opportunities posted under this code span landfill gas collection systems, park irrigation improvements, wastewater digester gas utilization, and municipal executive search services—none of which involve acid-based matrix stimulation, a technique typically applied in oil and gas well treatment to increase permeability and production. The mismatch between the code's nominal scope and actual solicitations suggests either tagging errors in the source records or that state and local governments rarely use this code for its intended purpose.

The three geographically dispersed opportunities—the Dalton-Whitfield Solid Waste Authority's landfill gas collection system expansion in Georgia (ITB PE75552NONST2026000000061, due May 21, 2026), the Eastern Municipal Water District's digester gas utilization design-build-finance-own-operate-maintain project in Riverside County, California (RFP 3900, due April 14, 2026), and the City of DeBary's park irrigation system upgrade in Florida (ITB 0315)—reflect solid-waste and water-utility procurement rather than oil and gas services. The Georgia landfill authority requires Georgia-licensed general contractors with minimum five years' landfill gas experience and 50 percent on-site labor; the California water district seeks proposers with five years' digester gas project experience and estimated bonding requirements of $20 million. No recent state or local opportunities in the source reflect acid-matrix stimulation work, and pursuit under this code should be treated as a watch-and-verify activity pending clarification of the code's actual application in your target markets.
