摘要: A method for formation testing in a wellbore, according to one or more aspects of the present disclosure comprises deploying a formation tester to a position in a wellbore; initiating a first pumpout process to draw formation fluid from a formation at the position into the formation tester; discharging a treatment fluid from the formation tester to the formation at the position; and drawing a formation fluid sample from the formation at the position into the formation tester.

摘要: A sample module for a sampling while drilling tool includes a sample fluid flowline operatively connectable between a sample chamber and an inlet, for passing a downhole fluid. A primary piston divides the sample chamber into a sample volume and a buffer volume and includes a first face in fluid communication with the sample volume and a second face in fluid communication with the buffer volume. A secondary piston includes a first face in fluid communication with the buffer volume having buffer fluid disposed therein and a second face.
