A method of removing fluid from a rock formation using a sampling tool includes deploying first and second probes of the sampling tool to first and second positions respectively along a wellbore within the rock formation. The method further includes simultaneously withdrawing fluid from the rock formation through the first and second probes during a first period of time. The method further includes disabling the second probe to prevent fluid from being withdrawn from the rock formation through the second probe after the first period of time. The method further includes withdrawing fluid from the rock formation through the first probe during a second period of time while the second probe is disabled. The method further includes disabling the first probe to prevent fluid from being withdrawn from the rock formation through the first probe and simultaneously withdrawing fluid from the rock formation through the second probe.
