After Haggerty and Seyler 1997 reprinted by permission of the Illinois State Geological Survey. minerals and the permeability of Aux Vases reservoir rocks by conducting dynamic constant rate injection coreflood experiments 2. Investigate how 15 HCL and MCA affects crude oil from Aux Vases reservoirs by conducting compatibility experiments 3. Examine how exposure to fluids of various salinities affects permeability in samples of Aux Vases reservoirs by conducting coreflood experiments 4. Investigate the effects of long-term contact of 15 HCL and MCA with pore-lining minerals in reservoir samples by conducting static soak experiments 5. Compare XRD analyses of the bulk mineralogy and SEM EDX analyses of pore-lining minerals with flood results to identify minerals that would be most affected by fluids commonly used during drilling completion and stimulation of Aux Vases reservoirs. Therefore Haggerty and Seyler 1997 carried out five sets of bench experiments with the specific objectives described in Table 15-4. The direct contact experiments have been conducted to determine the .
