What Ryder Scott does

Ryder Scott Company, L.P. is a privately held, Houston-headquartered petroleum consulting firm founded in 1937 that provides independent, science-based reserves evaluations, reservoir-engineering studies, and advisory services to the global oil and gas industry. The firm operates from three offices — Houston (headquarters), Denver, and Calgary — serving operators (Chevron, BP, ExxonMobil, Occidental, Diamondback, SM Energy, Kosmos, Marathon), national oil companies (ADNOC, SOCAR, PetroEcuador, ECOPETROL), financial institutions (Citi, Bank of America, Blackstone, Barclays), and government entities across North America, South America, Europe, the Middle East, Africa, Asia, and Australia. Services span upstream (reserves and resources evaluation, geosciences, reservoir simulation, EOR), integrated midstream/downstream consulting, sustainability (CCUS, Scope 1 GHG verification, geothermal, helium, lithium, 45Q certification), and advisory/training (M&A due diligence, expert witness testimony, custom programs). Engagement-based revenue is delivered through project-based professional-services contracts; the firm complements services with proprietary software — the Specialized Oilfield Software (SOS) suite (ProCast, Forecast, PTA, Tank) and the Reservoir Solutions Freeware (RSS) Excel tools — and a recurring subscription product for oil and gas price charts and forecasts.

The business model is built on credentialed, multidisciplinary expertise: the firm employs 251–500 people, including a deep bench of geophysicists, petrophysicists, geologists, reservoir engineers, economists, and strategists — many with prior careers at supermajors, IOC service companies, and bulge-bracket banks — and holds DEKRA ISO 9001 and ISO 14001 certifications. Ryder Scott is an active participant in SPE PRMS guidelines development and maintains thought-leadership channels including its 21st Annual Reserves Conference, newsletters, and SEC First Day of Month price publications. Reported transaction and field-evaluation tracks record include over $20 billion in technical transaction support and over 200 fields evaluated (per SVP Allan Chen), with President & COO Eric Nelson having led nearly $7 billion in M&A due diligence since 2018. Strategic priorities visible in recent activity (2024–2026) include ESG and CCUS service-line buildout, geographic deepening in Mexico (via the February 2025 Lumina Geophysical alliance), regulatory expansion into voluntary carbon markets (BCarbon VVB approval, October 2025), and a leadership transition from a retired Chairman Emeritus Guale Ramirez to a new 2026 Executive Committee led by Herman Acuna (Chairman & CEO), Eric Nelson (President & COO), and Tosin Famurewa (EVP & CBO).
