The Design and Use of a Field and Reservoir Data Base for Petroleum Exploration

NEHRING, RICHARD, NRG Associates, Colorado Springs, CO

Field and reservoir data bases can have many valuable applications in petroleum exploration. Realizing this value requires careful attention to several general and specific design considerations. The primary general design considerations include (1) developing standard field and reservoir definitions that are applied uniformly across political boundaries, (2) applying appropriate variable definitions consistently throughout the data base, (3) providing high rates of coverage for each variable, and (4) testing and editing the data thoroughly for consistency and correctness. Design considerations that are specific to intended uses of a field and reservoir data base include (1) the provision of complete field and reservoir size estimates, (2) the incorporation of a comprehensive set of p ay definitions, and (3) the use of cross-referencing variables to facilitate combined uses with the various well data bases.

Well-designed field and reservoir data bases provide a source of information between the often uninformative generality of aggregate statistics and the overwhelming detail of well data bases. They can be used as several different levels of aggregation. Their most valuable applications to exploration are found primarily in three areas: (1) basin, regional, and national reviews, (2) the generation of exploration concepts, and (3) evaluating prospects systematically within a play context.
