ABSTRACT:
A well completion and testing system and method. The system includes a tubing string having an integral locking sub and a testing probe assembly for use with well testing instruments and having an equalizing and bypass valve, the probe assembly being releasably lockable in the locking sub and adapted to be manipulated from the surface to open and close the valve for testing a well under both shut in conditions and flowing conditions. The method includes running a tubing string including an integral locking sub into a well bore, running a tool train including well testing instruments connected with a locking probe having an equalizing and bypass valve, releasably locking the probe in the locking sub of the tubing string, and selectively manipulating the probe from the surface to open and close the valve of the probe while taking measurements with the well alternately shut in and flowing.
