The use of geological analogs has been a common practice among geoscientists as shown in a recent survey study. The analogs are used by geoscientists and engineers in solving challenging problems in exploration, development and production. An efficient, intuitive and cost effective global analogs system with a large number of giant oil and gas fields makes it feasible to systematically use the analogs. Effectively using analogs as an integral part of E&P workflow will help reduce exploration risk, optimize field development options and enhance field productions. At C&C Reservoirs, we have realized the needs of the industry and made great efforts in the past decade in developing an efficient, intuitive and cost effective global analogs system, namely DIGITAL ANALOGS™ E&P Knowledge System. It has been adopted by the E&P industry worldwide since its inception. We applied the concept of Knowledge-Information-Data (K-I-D) system in the design and implementation of the global analogs system. The K-I-D based DIGITAL ANALOGS knowledge system is customizable to include user's own reservoir and field analogs. A wide range of applications of geologic analogs in E&P workflow is well recognized by the industry. The examples in deepwater exploration and carbonate reservoir development highlights the use of the Digital Analogs in the E&P efforts. The advent of the DIGITAL ANALOGS knowledge system makes the efficient use of analogs an integral part of E&P work flow from exploration to production.
