UNSPSC 71171900: Formation water testing services

Includes range of services involved in monitoring formation water elements in oil and gas production.

UNSPSC 71171900 Formation water testing services is a Class code that covers laboratory analysis and field testing of produced or formation water from oil and gas wells, including salinity, mineral content, microbial contamination, corrosion potential, and chemical composition assessments. State and local governments—primarily environmental regulators, state oil and gas commissions, water quality agencies, and regional environmental protection departments—solicit these services to monitor groundwater integrity, ensure compliance with water discharge regulations, and assess contamination risk at drilling operations. The work involves both routine baseline testing of formation water samples and emergency or investigative testing following spills, wellbore failures, or reports of water-quality degradation near drilling sites.

The source provided contains no recent state and local contract opportunities tagged under this code, preventing characterization of the issuing-body mix, geographic spread, or representative recent solicitations. Without posted RFPs, RFQs, or ITBs in the dataset, no pattern of repeat buyers, regional activity concentration, or current procurement intent can be identified from recent market activity.
