Provides reservoir rock and fluid analysis, crude-oil inspection, joint-industry studies, completion diagnostics, and perforating products for oil-and-gas operators. Work spans international and offshore reservoir projects, U.S. unconventional completions, and global manufacturing tied to drilling and production activity.
Measures reservoir rocks, reservoir fluids, crude oil, natural gas, water, and derived products so oil-and-gas clients can evaluate reservoir performance and recovery. Reservoir Description includes rock and fluid characterization, Saybolt inspection, proprietary studies, laboratory equipment, and appraisal support for CCS, geothermal, and mining projects.
Production Enhancement supplies completion diagnostics, perforating systems, stimulation testing, and well-abandonment products. ProTechnics, Owen Oil Tools, and Stim-Lab anchor current product families for tracer diagnostics, high-performance perforating, and proppant or energetic-solution testing.
Most Reservoir Description activity is tied to producing fields, development work, and crude-product movement outside the U.S.; Production Enhancement is more exposed to U.S. unconventional completions while also serving conventional projects globally. Activity depends on oilfield spending, technical execution, timely product development, and sanctions exposure in Russia.
