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 16):
A method of obtaining an effective bulk modulus of a managed pressure drilling system, the method comprising:\n obtaining a first effective bulk modulus; measuring the material bulk modulus of the drilling fluid in the managed pressure drilling system; calculating the portion of the first effective bulk modulus not originating from the material bulk modulus of the drilling fluid; changing the drilling fluid in the managed pressure drilling system, wherein the material bulk modulus of the new drilling fluid is known or measured; and calculating a second effective bulk modulus of the managed pressure drilling system using the portion of the first effective bulk modulus not originating from the material bulk modulus of the original drilling fluid and the material bulk modulus of the new drilling fluid,
