Abstract
A system is described for monitoring a subsea formation, which is under development. Instruments located in a completed but unconnected well are employed for providing information by a provisional monitoring unit being lowered downhole and connected to the well. Changes in the reservoir as a result of operations in other adjacent wells are intercepted by the instruments in the well and transmitted via an acoustic link to the surface.
