Paper: Considerations In Creating And Using A Relative Permability Database

Having reliable and readily accessible relative permeability information is a problem for many reservoir engineers, particularly for waterflooding and other reservoir simulation calculations; currently, no central repository exists and data within a company is often not centrally organized. A large effort was required to collect data from public and private sources and modify it to fit a common format. The central database thus constructed maintains relative permeability data in a format that is easily retrieved and processed. Categorizing and modifying the original data for applicability to similar systems is considered, allowing for variations in connate water, residual oil, and critical gas saturations. The database must be easy to use and employ both tabular and graphical results. The software is menu-driven and selects data from central relative permeability files. Information such as fluid type, wettability, lithology, geographical location, and method of measurement is used to search applicable results. The program operates under W9X or NT 4.0 systems. The database may be downloaded at no charge from a University of Missouri-Rolla web page.
