Abstract:
Systems and methods for signaling the detection of a fluid change in a wellbore can be used during wellbore operations, such as cementing a casing in the wellbore. The systems and methods involve using burst discs to provide a pressure pulse that can be detected uphole and there by provide a signal related to when a fluid change has reached a predetermined position in the wellbore. The burst discs can be activated to prevent fluid flow in a portion of the wellbore by a sensor that detects a property that is different between two fluids. Once activated, the pressure of the fluid on the burst discs subsequently ruptures the burst disc and creates the pressure pulse.

Claim (Index 6):
The method of  claim 5 , wherein the burst disc is located within the central bore and, when activated, the burst disc stops the flow uphole in the casing until the second pressure is reached.
