A successful field evaluation and enhanced oil recovery (EOR) program design was accomplished with the aid of a field database system. Rigorous date handling, date screening and a date entry front-end were concluded to strongly influence the utility of the working database. Versatile manipulation of the database allowed the extraction of date in a variety of forms. Mapping of die date reveal»! production patterns and indicated reservoir dynamics. The results were an accurate assessment of the remaining reserves and the formulation of an appropriate EOR program.
