Abstract
A method for performing an integrated cementing operation at a wellsite is disclosed. The method involves simulating a cementing operation including pumping sequences for selectively pumping drilling fluid and cement into the wellbore according to pre-operation simulated pumping parameters, measuring real-time pumping parameters of the drilling fluid and the cement according to the pumping sequences, during the measuring, simulating real-time pumping parameters for each of the defined pumping sequences based on the measured real-time pumping parameters, and comparing the real-time simulated pumping parameters with the pre-operation simulated pumping parameters. The method may also involve measuring a return flow rate of fluid flowing out of the wellbore, defining a loss zone within the wellbore, simulating the return flow rate based on the input flow rate, and generating a rate of the fluid loss such that the simulated return flow rate equals the actual return flow rate.
