Abstract: A method includes conveying a wireline toolstring into a wellbore to perform a downhole operation, wherein the wireline toolstring has a single packer disposed thereon. The method also includes positioning the wireline toolstring in the wellbore adjacent a zone of interest, wherein the zone of interest has a barrier is located at one end of the zone of interest and the wireline toolstring is positioned such that the single packer is located adjacent the zone of interest such that the zone of interest is between the single packer and the barrier. The method can also include setting the single packer and performing a wellbore operation.

Abstract: A downhole tool designed to be disposed in a borehole of a subterranean formation is provided. The downhole tool includes a probe used to interface with the subterranean formation in order to sample fluid from or to inject fluid into the subterranean formation. The downhole tool also includes a sample flowline fluidly coupled to the probe and used to direct fluid through the downhole tool. The downhole tool further includes at least two volume chambers. These volume chambers each include a first side fluidly coupled to the sample flowline, a second side fluidly coupled to the guard flowline, and a piston separating the first side from the second side. The downhole tool is able to control a flow of fluid from a high pressure environment to a low pressure environment via the at least two volume chambers, the sample flowline, and the guard flowline.
