Abstract:
In one aspect, a method of obtaining a fluid from a formation is disclosed that in one embodiment may include: pumping fluid received by a first probe from the formation into the wellbore; pumping fluid received by a second probe from the formation into the wellbore; determining when the fluid received by one of the first and second probes is clean; and pumping the fluid received by the first probe into a sample chamber while collecting the formation fluid received by the second probe from the formation into a storage chamber having an internal pressure less than the pressure of the formation.
