Abstract
An example instrumented formation tester for injecting fluids and monitoring of fluids described herein includes a downhole tool which can be deployed in a wellbore via a wireline or a drill string. The downhole tool may facilitate the injection of fluids into an underground formation, and the monitoring of the directions in which the injected fluids flow in the formation in an open hole environment. In particular, the downhole tool may be configured for removing the mud cake from a portion of the wellbore wall for facilitating a fluid communication with the formation to be tested.
