Acid Treatment of Wells Demir 1995 simulated the treatment of the Morgan Coal no. 3 well in Energy Field Williamson County Illinois using mud-cleaning acids MCA . Table 17-5 presents the reservoir mineralogy data from a nearby well the Morgan Coal no. 2 well used by Demir 1995 for the Morgan Coal no. 3 well. Figure 17-16 by Demir 1995 describes the hypothetical zones around the well considered for simulation of the MCA treatment of the near wellbore formation. Considered for simulation were and 15 HCL-MCA solutions containing molal KCL clay stabilizer and Model Assisted Analysis and Interpretation of Laboratory Field Tests 583 ---------------------------------------------------------------- r2 1 X x 91 Xx X.
