Abstract: To effectively distinguish and accurately use America PRMS and SEC reserves evaluation rules, we compared and analyzed the two reserve classification systems. The two reserve rules have similarities and differences. The reserves must be found, recoverable, economical and with economic surplus to be confirmed by both PRMS and SEC. The SEC not only evaluates proved reserve as dose PRMS but also evaluates possible and probable reserve. The differences between the PRMS and the SEC include liquid contact, fault upthrow and down throw reserve definition, PUD offset, analogy reservoir, reliable technique, 5 year PUD plan,economic, oil price & cost. The SEC reserve evaluation is based on the present economic circumstance, because it emphasizes oil and gas economical production and the lowest income of the company. The PRMS reserve evaluation is bases on forecasting economic circumstance, as it concerns the commercial value of the reserve and the return of the company's investment.

Key words: PRMS, SEC, reserve rule, classification system, proved reserve, oil & gas reserve
