The conclusions that can be drawn from the 3-dimensional physical simulator system are as follows: 1. The 3-D laboratory simulator is capable of evaluating the effect of different injection and production schemes. This work compared the use of vertical and horizonal injection wells in miscible carbon dioxide flooding. Other combinations of injection/production schemes could be studied as well. 2. A relative increase in oil production of approximately 24% is seen when utilizing the horizontal well for carbon dioxide injection as compared to a vertical injection well. 3. An approximate economic analysis indicates that the additional oil recovery generated can more than offset the cost of the horizontal lateral drilling. 4. The horizontal injector resulted in lower instantaneous gas-oil ratios when compared to the vertical injection well. This is most likely due to the more efficient contact between carbon dioxide and the oil that is created by the horizontal well. 5. For the laboratory simulator, the investigators saw no real effect of carbon dioxide injection rate (or velocity) on the recovery results. The follow conclusions can be drawn from the polymerization project: 1) An apparatus was constructed that permits in situ generation of polymers in supercritical carbon dioxide and also allows the measurement of the viscosity of any resultant carbon dioxide/polymer system. 2) Light olefins may be readily polymerized in an environment of supercritical carbon dioxide using commonly available initiators. 3) While polymers have been made, no apparent viscosity increases have been measured. 38 refs.
