Abstract: A downhole acquisition tool having a formation testing module is provided. The formation testing module includes a fluid chamber comprising a piston and configured to store a fluid and to receive a flowback fluid from a geological formation, wherein the fluid is substantially free of solids. Additionally, the formation testing tool has a first conduit fluidly coupled to the fluid chamber and extending from a flowback conduit and a first outlet of the formation testing module, wherein the flowback conduit is configured fluidly coupled to the geological formation. and configured to receive the flowback fluid from the geological formation, and wherein the first conduit is configured to receive the flowback fluid from the flowback conduit. Further, the formation testing module has a first flow control device positioned downstream from the fluid chamber, wherein the first flow control device is configured to control a flow of the fluid exiting the fluid chamber.

Abstract: A sampling apparatus, comprising a primary flowline, a secondary flowline, a dump flowline not provided downstream of the secondary flowline, and a relief valve provided in the dump flowline, may be disposed in a wellbore penetrating a subterranean formation. A method of use of the sampling apparatus may comprise flowing fluid from the subterranean formation and into the primary flowline; diverting fluid from the primary flowline to a sample chamber through the secondary flowline; diverting fluid from the primary flowline to the wellbore through the dump flowline; and controlling the pressure in the sample chamber using the relief valve. The sampling apparatus may be used to terminate storage of a fluid sample in a sample chamber while continuing to pump fluid from the formation.
