Abstract
A method for fluid pressure testing of a formation behind casing is set forth. A formation testing tool is lowered into the well to a specified depth opposite a formation of interest behind a casing. A test probe is extended and a perforation is formed from the test probe into the formation to obtain fluid communication with the formation. Utilizing a storage container in the testing tool, fluid is pumped from the formation into the test tool, or from the test tool into the formation and formation pressures are measured at selected intervals.
