Foreign fluids and/or entrained solids introduced during various phases of well development reduce the intrinsic reservoir productivity by blocking the effective flow path. Oil/gas recoveries, therefore, can be enhanced significantly if better quality control is established for all well treatment fluids by assessing rock/fluid and fluid/fluid compatibilities before field use. A capillary-pressure method, developed for evaluating the formation damage or stimulation potential of well treatment fluids, uses relative changes in pore-entry pressure, shape of the capillary-pressure curve, and residual wetting-phase saturations as measures of damage or stimulation in core plugs exposed to various treatment fluids.
