Abstract
The present invention provides methods and apparatus for simulating well bore conditions before and after cementing therein. The methods of the invention are basically comprised of the steps of circulating a drilling fluid through a closed test cell containing a permeable rock core while maintaining a selected pressure differential across the rock core to form a layer of filter cake thereon, circulating a filter cake removal fluid through the test cell to simulate the clean-up of the well bore and then determining the condition of the rock core with respect to the effectiveness of the filter cake removal fluid thereon.
