What Reservoir Group does
Reservoir Group is a privately held niche oilfield services company headquartered in Houston, Texas, and owned by Madison Industries. The company serves E&P operators and large oilfield service companies globally through four integrated service lines: Coring (QuickCapture pressure coring, Jam Mitigation Suite including Multi-Jam Shield and JRS4, Liquid Trapper saturation coring, ResDOC); Drilling Tools (WedgeTail Roller Reamer with patented Taloc locking mechanism, ShingleBack IB Stabilizer); Well Intervention (INFOCOIL real-time coiled tubing data system, Tidal Force Tool multi-cycle flow diverter, Max-Drill motors, ProDrill Velocity composite frac plugs via authorized dealer, debris management tooling); and Well Monitoring (piezo and quartz memory gauges for HPHT environments, real-time fiber optic monitoring, and proprietary software including Vita, Graph, Gateway, Pulse, and MLTMod). The company operates 51 locations across 27 countries on six continents, generating revenue through hardware sales, professional services, and authorized dealer arrangements, with enterprise field sales to E&P operators as the primary go-to-motion.
The business is built on 70+ years of accumulated expertise consolidated from 14 legacy brands (DOWDCO, Corpro, Canada Tech, Omega Well Monitoring, Quest Coring, Wellvention, Empirica, among others) under Madison Industries' ownership. Reservoir Group's revenue model combines proprietary hardware sales (gauges, roller reamers, motors, frac plugs) with project-based professional services for coring and well intervention, supported by certified quality and HSE systems (API Q1, API Q2, ISO 9001:2015, ISO 45001:2018, ISO 14001:2015). In February 2020 the company divested its Mamba drilling turbine product line to STORMELO Investments Inc. to refocus on core strategic priorities, and has since expanded into the Carbon Capture, Utilization, and Storage (CCUS/CCS) vertical — including Class VI well monitoring — as a new addressable market.
