Summaries are presented for the following research projects: (1) geoscience application to the prediction of reservoir variations; (2) reservoir screening and recovery predictions; (3) EOR environmental compatibility; (4) development of improved oil mobilization concepts; (5) gas miscible displacement method; (6) mobility control mechanisms of steamflooding additives; (7) improvements in stimulation technology; (8) steamflooding with additives; (9) recovery processes - chemical; and (10) development of improved immiscible gas displacement methodology. Some of the highlights for this period are: (1) for extremely low permeability core it was found that low pH-methanol and heptane prepads are effective in reducing formation damage and clean-up time, with heptane the most effective; (2) core from the coastal zone of MWX-1 has lower permeability than those in the palludal zone, and take longer to clean up; (3) coreflood experiments with microbes showed that the pressure in the core can increase by 20 to 40 psi within 48 hours, indicating that gas generated by microbes can provide energy to mobilize oil; (4) in situ generation of blocking emulsion in Berea core was found to be able to reduce permeability of the core, injection of externally produced emulsion reduced the permeability by an additional 43%; and (5) an accurate correlation for CO/sub 2/ viscosity has been successfully developed. This correlation can predict CO/sub 2/ viscosity with +-2%.
