DPARS Production and Reserves System: Evolution of a Corporate Tool

Abstract

The authors describe the evolution of a customer-driven, fit-for-purpose database tool that intelligently combines reserves, production, entitlement/sales, capital expenditures (Capex), operating expenditures (Opex), well scheduling, and separator test data. The tool, Deminex Production and Reserves System (DPARS), evolved from a single-user application on a portable personal computer (PC) to a networked, multiuser, corporate tool used worldwide in a midsize international oil and gas E and P company.
