What GeoMark does

GeoMark Research, Ltd. is a privately held, Houston-headquartered geochemistry and PVT laboratory founded in 1990 by Stephen Brown and Dr. John Zumberge. The firm provides integrated fluid and rock characterization services to upstream oil and gas operators, refiners, traders, government geological surveys, and — increasingly — carbon capture and sequestration operators and critical-minerals explorers. Service lines span oil analysis, source rock analysis, PVT analysis, mud gas isotope analysis, water analysis, production allocation, and basin studies, supported by a global laboratory footprint in Houston (Oil & Source Rock Lab), Lafayette, Louisiana (PVT/Gas Isotope Lab), and Kuala Lumpur (GeoMark Research Sdn. Bhd.). The company is family-led, with Ethan Brown as President and Dr. Alex Zumberge as Executive Vice President, and is now in its second generation of founder-family ownership.

The technical core of the business is RFDbase™, a proprietary rock, fluid and PVT database containing over 910,000 standardized samples built up over more than 35 years. RFDbase underwrites a suite of trademarked, productized workflows including TruSat™ and CutSat™ (dual-retort saturation analysis with ~99% collection efficiency on whole core and drill cuttings), CrudeView™ (standardized global crude valuation across 15,000+ samples), PlumeView™ (time-lapse CCS plume and seal monitoring), and the Integrated Reservoir Fluid Intelligence™ (IRFI) framework, which combines PVT, isotope, biomarker and production-allocation interpretation. Instrument capability includes Agilent 8900 ICP-QQQ-MS, GC-QQQ-MS quantifying 215+ transition ions, ultra-high-resolution gas chromatography, Rock-Eval/HAWK pyrolysis, vitrinite reflectance petrology and digital rock workflows.

GeoMark makes money through a mix of fee-for-service analytical work (per-sample / per-project, quote-based), recurring data subscriptions to RFDbase and CrudeView, and pre-packaged or custom basin studies. Distribution is a combination of direct enterprise field sales via regional Business Development Managers, self-serve/demo-driven onboarding for the RFDbase portal, and technology-partner channels (notably a 2025 joint toolkit with GIS-PAX and S&P Global for exploration workflows, and a 2025 co-developed CCS service with Petricore). The customer mix is anchored on mid-market E&P operators (Sabine Oil & Gas, Spur Energy Partners, Ensign Natural Resources) plus government agencies (Geoscience Australia), with expanding reach into refiners, traders, CCS developers and critical-minerals explorers.

Core offering

GeoMark Research operates a geochemistry and PVT laboratory platform that delivers standardized analytical services (Oil, Source Rock, PVT, Mud Gas, Water, Production Allocation, Critical Metals, TruSat™/CutSat™) and subscription access to RFDbase™, the industry's largest rock/fluid/PVT database of 910,000+ samples, alongside data platforms such as CrudeView™ for crude valuation, PlumeView™ for CCS monitoring, and the Integrated Reservoir Fluid Intelligence™ (IRFI) framework. The company serves upstream oil & gas operators, refiners, traders, CCS projects and government agencies with global delivery from laboratories in Houston, Lafayette and Kuala Lumpur.

Product overview

GeoMark Research delivers an integrated, end-to-end geochemistry and PVT laboratory platform built around a core RFDbase™ data backbone and a modular service portfolio spanning exploration, development, and production workflows. At the foundation is RFDbase™, the industry's largest rock, fluid, and PVT database (910,000+ standardized samples over 35+ years), which feeds and is enriched by named analytical services — Oil Analysis, Source Rock Analysis, PVT Analysis, Mud Gas Analysis, Water Analysis, Production Allocation, Critical Metals, Basin Studies, and CO₂ Sequestration and Monitoring — and proprietary productized workflows including TruSat™ (with its CutSat™ cuttings extension), CrudeView™, PlumeView™ (under the GeoMark–Petricore CCS offering), and the Integrated Reservoir Fluid Intelligence™ (IRFI) framework. Together these products convert fluid and rock samples into standardized, decision-ready intelligence for operators, refiners, traders, and CCS projects worldwide, with regional delivery via GeoMark Research Sdn. Bhd. in Kuala Lumpur and the Lafayette PVT/Gas Isotope Lab alongside the Houston Oil & Source Rock headquarters.
