Abstract
A method for sampling fluid from a subsurface formation includes retrieving fluids from the formation using a plurality of pumps. The method also includes the steps of controlling a flow of the retrieved fluids using at least a first valve and a second valve and estimating an operating parameter of at least one pump of the plurality of pumps. The method further includes the step of controlling the first valve and the second valve using the estimated operating parameter to initiate a fluid sampling event.
