About
Ryder Scott Company, L.P. is one of the world’s most respected independent petroleum consulting firms, providing trusted technical and economic evaluations for more than eight decades. Founded in 1937, we specialize in the evaluation, certification, and audit of oil, gas, and low-carbon energy resources under SEC, PRMS, and international reporting standards. From reserves and resource assessments to field development studies, production forecasting, and economic evaluations, our work supports clients in quantifying value, managing risk, and making informed decisions across the energy value chain. With offices in Houston, Denver, and Calgary, Ryder Scott serves clients in over 100 countries—including national oil companies, independents, financial institutions, and governments—delivering independent advisory services that stand as a global benchmark for integrity and technical excellence. Our multidisciplinary teams of petroleum engineers, geoscientists, and economists bring deep technical expertise and an unwavering commitment to accuracy and objectivity. That independence is the foundation of our reputation and the reason our certifications are trusted by regulators, investors, and operators worldwide. As the energy landscape evolves, Ryder Scott continues to expand its capabilities across carbon capture and storage (CCS), geothermal, hydrogen, and renewable projects, applying the same rigorous standards and analytical depth that have defined our work for more than 85 years. At Ryder Scott, credibility isn’t claimed—it’s proven. Learn more at www.ryderscott.com
