Abstract
A method of cleaning a well face during formation testing at a drill site is disclosed. A collection chamber disposed in a formation tester tool may be at least partially filled with cleansing fluid. The formation tester tool may be introduced into a wellbore and the cleansing fluid may be ejected through a probe coupled to the formation tester tool. The collection chamber may then be at least partially filled with a formation fluid sample. A face of the probe may be contacted by a retractable cleaning mechanism coupled to the formation tester tool.
