ABSTRACT:
A method for testing drilling compounds, particularly drilling fluids and cements to determine the drilling fluid and cements ability to seal porous formations surrounding the borehole. The method would generally comprise obtaining a representative sample of drilling compound for testing, particular drilling fluid or cement, that has been or will be injected down the borehole and recovered for testing. The sample of fluid is then filtered through a filter press or the like having a porous filter disk with measured size openings that can be closely controlled, or having absolute filtration ability. The sample is then filtered through the disk, usually under pressure, and the rate or the time that the drilling fluid takes to seal a specific size opening in a specific disk is recorded by the number of cubic centimeters of drilling fluids that is recovered until such a seal is established. The test is conducted for a prescribed period of time (30 min.) and the number of cubic centimeters of filtrate recovered is recorded to determine fluids wall cake building ability.
