The EPMI Malay Basin Petroleum Geology Database: Design Philosophy and Keys to Success: ABSTRACT

Esso Production Malaysia Inc. (EPMI) developed and populated a database containing information collected in the areas of basic well data: stratigraphy, lithology, facies; pressure, temperature, column/contacts; geochemistry, shows and stains, migration, fluid properties; maturation; seal; structure. Paradox was used as the database engine and query language, with links to ZYCOR ZMAP+ for mapping and SAS for data analysis. Paradox has a query language that is simple enough for users. The ability to link to good analytical packages was deemed more important than having the capability in the package. Important elements of design philosophy were included: (1) information on data quality had to be rigorously recorded; (2) raw and interpreted data were kept separate and clearly identified; (3) correlations between rock and chronostratigraphic surfaces were recorded; and (4) queries across technical boundaries had to be seamless.
