ABSTRACT:
Discloses apparatus and method for testing, then treating, then testing the same sealed off region of earth formation within a well bore. Employs a sealing pad arrangement carried by the well tool to seal the test region to permit flow of formation fluid from the region. A fluid sample taking arrangement in the tool is adapted to receive a fluid sample through the sealing pad from the test region and a pressure detector is connected to sense and indicate the build up of pressure from the fluid sample. A treating mechanism in the tool injects a treating fluid into said sealed test region of earth formation. A second fluid sample is taken through the sealing pad while the build up of pressure from the second fluid sample is indicated.
