This is the final report of a two-year project which had four major task areas. A substantial portion of work carried out under this project has been reported in detail in journals, the First Annual Report to the Department of Energy or in manuscripts which have been submitted for publication and are available on request. In such cases only major conclusions are reported, along with reference to the detailed accounts. Work is reported for the following 4 major tasks: (1) residual saturation measured by laboratory core flooding (core flooding experiments, contact angle measurements); (2) effect of high pressure gradients on residual oil saturations (capillary number relationships, residual oil flushing at wellbore, electrical resistivities at reduced residual oil saturations); (3) mechanisms of mobilization and entrapment of residual oil (magnitude and detailed structure of residual oil saturations, effect of interfacial tension on the stability of displacement fronts, effect of pore shape on displacement curvatures); and (4) residual oil structure (analysis of blob-size distributions by Coulter counter, changes in residual oil structure with oil recovery). 53 references, 76 figures, 46 tables.
