    Abstract: A method includes lowering a downhole tool via a pipe into a wellbore drilled through a formation via the pipe and establishing a fluid communication between the downhole tool and the formation at a location in the wellbore. The method also includes extracting from the formation a first fluid stream through the fluid communication and passing the first fluid stream through the downhole tool for a first duration. The method further includes breaking the fluid communication between the downhole tool and the formation, moving the pipe in the wellbore, and reestablishing the fluid communication between the downhole tool and the formation essentially at the location in the wellbore subsequent to moving the pipe in the wellbore.

    Abstract: A method includes drawing formation fluid from a formation into a pressure test chamber of a downhole tool while the downhole tool is positioned at a location within a wellbore. The method also includes, while the downhole remains positioned at the location, measuring pressure of the formation fluid drawn into the pressure test chamber and operating a first pump to route additional formation fluid from the formation through the downhole tool and out into the wellbore. Still further, the method includes operating a second pump to expel the formation fluid from the pressure test chamber and to mix the formation fluid with the additional formation fluid such that the formation fluid expelled from the pressure test chamber is also routed through the downhole tool and out into the wellbore along with the additional formation fluid.

    Abstract: A method for routing a fluid within a flowline of a downhole tool is provided. In one embodiment, the method includes moving a piston within a chamber of a downhole tool to push a fluid out of the chamber and into a flowline. The method also includes using a pump in the downhole tool and in fluid communication with the flowline to route the fluid within the downhole tool via the flowline while moving the piston within the chamber. Additional systems, devices, and methods are also disclosed.
