Prator Bett

What Prator Bett does

Prator Bett, LLC is a petroleum engineering consulting firm founded in 1999 and headquartered in Houston, Texas, that provides independent third-party reserve and economic evaluations of oil and gas properties. The firm primarily serves small to mid-size public and private oil and gas companies, as well as major and regional banks, delivering economic evaluations packaged as bound reports for SEC year-end reporting, acquisitions, divestitures, due diligence, estate planning, field studies, budgeting, and financing purposes. The firm also performs borrowing base value reviews for bank lending decisions and conducts reservoir engineering work including complex field studies and secondary/tertiary recovery projects, with prior evaluation work spanning nearly every US producing basin plus Colombia, Canada, the UAE, and the former Soviet Union.

The firm operates on a project-based professional services model with no publicly disclosed pricing, generating revenue through consulting engagements where fees are determined by project scope, complexity, and the extent of evaluation required. Work is delivered by a small team of three to five personnel anchored by co-founders and managing partners M. Drayton Prator, III (Vice President) and Thomas G. Bett (President), supported by an engineering technician. Prator Bett uses industry-standard software tools—primarily ARIES for cash flow modeling and PHDwin for secondary analysis, supplemented by custom Excel spreadsheets for foreign concessions and special projects—alongside public data sources including Drilling Info and IHS Energy for production and well data. The firm holds no patents, has no external funding or parent company, has no recent M&A or product launches, and articulates a stated strategy to "grow modestly" while maintaining high-quality service from experienced engineers at reasonable cost.

Prator Bett is privately held, organized as a Texas LLC, with ownership and control concentrated between its two founding partners who collectively bring over 80 years of petroleum engineering consulting experience from prior senior roles at Huddleston & Co., Inc. The firm relies entirely on reputation and professional referrals for new business rather than formal marketing, and its customer base is segmented horizontally across oil and gas operators (mid-market primary) and banking/financial institutions (enterprise, for borrowing base reviews), with no public company disclosures, third-party validation, or verifiable revenue figures available.
