ABSTRACT:
A well testing system and method in which a by-pass valve is positioned in the tubing and a probe run on a line from the surface opens and closes the valve with vertical movement of the probe. The probe when landed in the valve is exposed to formation fluids and may transmit back to the surface, or may record information about the formation. The probe may also collect a sample of fluid to return to the surface with the probe.
