An example downhole tool configured for conveyance in a wellbore extending into a subterranean formation comprises a first fluid communicator configured to allow drilling fluid communication with an annulus between the downhole tool and the wellbore, a second fluid communicator configured to direct formation fluid to the annulus, and a formation testing device disposed deeper in the wellbore relative to the first fluid communicator and configured to pump formation fluid from the formation to the second fluid communicator. At least one of the first and second fluid communicators comprises a jet pump.
