Title:
TECHNIQUE AND APPARATUS TO PERFORM A LEAK OFF TEST IN A WELL
Document Type and Number:
WIPO Patent Application WO/2009/077867
Kind Code:
A3
Abstract:
A technique that is usable with a well includes deploying at least one sensing device in the well and during a leak off test, communicating a signal that is indicative of a measurement that is acquired by the sensing device(s) over a wired infrastructure of a drill string. The technique includes controlling the leak off test based at least in part on the communication.
