The first year's progress of a project having 4 major task areas is covered. Substantial progress has been made in each task area, and it is expected that all tasks will be completed during the second year of this project. The first task is to establish the limits of reliability of laboratory waterflooding as an evaluation tool. This work is being extended to the wetting properties of crude oils and selected aspects of core flooding procedure, such as the effects of overburden pressure and the properties of displaced and displacing fluids. The second task concerns the effects of high capillary number flows on trapping phenomena and residual oil saturation. The third task deals with mechanisms of mobilization and entrapment. Detailed accounts have been presented of work on relative permeability at reduced residual oil saturations and for factors which affect the magnitude and distribution of residual oil. Work on the fourth task concerns the detailed structure of residual oil. The technique of using a nonwetting phase which will solidify and can be separated from the rock has been applied. 32 references.
