Abstract
A wellbore material transfer system is disclosed, and comprises a downhole fluid conductor defining a downhole-conducting fluid passage, an uphole fluid conductor defining an uphole-conducting fluid passage, a flow controller for opening and closing the uphole-conducting fluid passage, and a completion disposed within a wellbore and defining a wellbore interval between the completion and the wellbore, the completion including selectively openable first and second flow communicators. While the flow communicators are open and the uphole-conducting fluid passage is closed, a subterranean formation zone may be fractured, and flow communication is absent, via the second flow communicator and the uphole-conducting fluid passage, between the wellbore interval and the surface. While the flow communicators and the uphole-conducting fluid passage are open, the wellbore interval may be gravel packed, and a solids-depleted fluid is conductible, via the second flow communicator and the uphole-conducting fluid passage, from the wellbore interval to the surface.
