.... To prevent the use of the wrong fluid, Expert systems were developed by ARCO and others. However, these tools were based on rules of thumb, providing no analytical solutions. Past experience indicates that knowledge systems are often discarded by the engineer after a few uses and have only found utility...

... such as a database, case base, knowledge base, expert help, on-line help, multiple-applications, and guidance board/map. The paper also discusses the reusability of code that is derived for a different application. Finally, the paper illustrates how we use this approach to develop a comprehensive software system...

... "rules" relating the combination of logs (SP, GR, caliper, resistivity, density, neutron, sonic, etc.) and basic information are included in the knowledge base. The Expert System uses the Kappa-PC Shell and is composed of three sub-systems: 1) an inference engine, 2) a knowledge base, and 3) a user...

... studies. Knowledge of the fluid properties required for various applications and the technically appropriate and cost effective methods for obtaining the data can save time and money. The likelihood of obtaining representative data is increased. In order to provide advice on the fluid property needs...

... characteristics. The knowledge base has been developed using a professional inference engine. To be closer to the type of reasoning used by experts, fuzzy logic concepts have been introduced in the knowledge representation. This approach leads to a methodology for selecting EOR processes and for improving know...
