Abstract:
A method of obtaining an effective bulk modulus of a managed pressure drilling system  1 , the method comprising: generating a pressure wave in the system  1 ; measuring the time interval for the pressure wave to travel over a distance in the system  1 ; and calculating the effective bulk modulus of the system  1  using the time interval and the length.

Claim (Index 12):
A method as claimed in  claim 1 , wherein the time interval is the time taken for the pressure wave to pass from a pressure sensor to a reflection location and back to the pressure sensor.
