Zusammenfassung:The present invention is to a tool for testing various zones in a well without having to remove the drill string containing the tool(s) from the well. Each of the individual fracture test tool has an internal passage that can be blocked by a ball bearing to close off the passage. Increased fluid pressure on the internal passage causes a valve body defining the passage to move to open windows in the tool. A collet reset tool is insertable through the passage to pull the valve body back into the run in position to close the windows without requiring the tools be raised to the surface to reset the fracture test tools.
