ABSTRACT:
Well testing apparatus including a landing receptacle for placing in a well tubing, preferably near the well packer, and a well test tool lowerable with instrumentations into the tubing on a flexible line and anchorable in the landing receptacle, the test tool then being actuable between open and closed positions by tensioning and relaxing the flexible line to open and close the well at the downhole location so that well conditions therebelow can be determined, the test tool having a mechanism for propping the raisable portion of the test tool in its upper position automatically in response to raising it from its lower position, the prop mechanism being releasable only after the flexible line has been tensioned and relaxed a plurality of times to permit the raisable portion of the test tool to return to its lower position. Methods of testing wells through use of the claimed well testing apparatus are also disclosed.
