ABSTRACT

In the case of reservoir-control volumes, by combining all production and injection rates, we can assume all injectors and producers as a tank which has only one injector and one producer. Assuming the connectivity factor fF is equal to unity, CRMT model is expressed as:

tk k ( )t )t( ( )e F( )k=

(1)

where τF is the time constant of reservoir; qF k( )t is the total fluid production rate at time tk; IF

( )k is injection rate of reservoir during time interval tk−1 to tk.
