Abstract
The present disclosure is directed to a formation test tool having similar, even identical, fist and second test probes which have supported snorkels thereon. They extend from the tool into a particular formation. One serves as an inlet and the other serves an outlet so that fluid can be removed from the formation, directed through the tool body, and returned to the formation through the other of the two snorkels. The fluid flow passes a test instrument which detects changes indicative of reduced well fluid invasion in the connate formation. A test procedure is also set forth for testing this fluid.
