What Advanced Resources International does

Advanced Resources International (ARI) is a privately held, founder/management-owned energy consulting firm founded in 1990 and headquartered in Arlington, Virginia (Washington, DC area), with additional offices in Knoxville, Tennessee and Columbus, Ohio. The firm delivers project-based technical advisory services across six practice areas—Unconventional Oil & Gas, Enhanced Oil & Gas Recovery, Geologic Storage of CO2 & Other Gases, Geothermal, Rare Earth Elements & Critical Minerals, and Economics/Policy/Regulatory & Standards. Its work combines geology, engineering, and economics for subsurface evaluation, reservoir characterization, and full project lifecycle support from screening through permitting and operations. Clients span oil & gas operators (Occidental, Teck Cominco), government and multilateral bodies (U.S. DOE, EIA, EPA, UNECE, Global Methane Initiative), and CCUS/energy developers, across the United States and 30+ countries.

The firm's core technical asset is COMET3, a proprietary reservoir simulator for gas shale, shale oil, and coalbed methane originally developed in the early 1980s and positioned as an industry standard, featuring triple-porosity/dual-permeability modeling and multi-component sorption for enhanced coalbed methane recovery and carbon sequestration. ARI supplements this with a deep publication and data library, including the Coal-Seq Consortium (500+ files) and an annual U.S. CO2 EOR Survey tracking ~140 projects and 219,700 bbl/d of production. In carbon storage it has developed 30+ Class VI permit applications and drilled 15+ Class VI project wells, and it applies machine learning/deep learning approaches to characterize geothermal systems and screen Enhanced Geothermal Systems designs.

ARI operates a sales-led, professional-services business model: revenue is generated through project-based consulting engagements won via direct business development, industry reputation, and specialized expertise. Pricing is quote-driven and not publicly disclosed. The firm is led by President & Chairman Vello A. Kuuskraa (40+ years experience, co-author of the EIA-sponsored World Shale Gas and Oil Study) and CEO George J. Koperna Jr. (U.S. Head of Delegation to ISO TC 265). Its ~60-person senior team of engineers, geoscientists, and project specialists, and its DCAA-compliant accounting posture, indicate meaningful reliance on federal government contracting.
