Abstract
Summary This paper describes Chevron U.S.A. Production Co.'s data extract system, CDX. CDX integrates our corporate mainframe databases with a set of ad hoc data analysis tools. Tools include statistical analysis software, database packages, and a widely used spreadsheet. CDX allows the user, through a single user interface, to access and retrieve data from a variety of databases written in industry-standard languages. CDX also allows access of large indexed data sets, such as Chevron's digital well-log archives. Data are delivered to the user's work environment—mainframe, workstation, or PC—ready to be loaded into ad hoc analysis programs or technical applications. This approach to system integration gives users the ability to mix, match, and reanalyze both technical and financial data in ways only experts could previously. Examples of how CDX has increased our ability to manage business more effectively include analyzing individual wells and patterns for profitability and optimizing flood operations by generating maps of individual well plots. The benefits of CDX are numerous, considering the business pressures now in effect that drive companies harder than ever to reduce operating costs, increase production, and optimize property portfolios. CDX offers a way to realize the benefits of data integration without having to rewrite multimillion-dollar data systems immediately. CDX also provides an organized way to shift information systems, data, and work processes to the newer relational technologies. Lastly, information derived from operating CDX is allowing Chevron to plan and optimize new relational data models and information systems.
