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.

Abstract: Systems and methods for evaluating a cement installation are provided. In one example, the cement may be evaluated using an objective indicator or index calculated from acoustic measurements. In another example, the cement may be evaluated in an integrated cement evaluation that integrates data relevant to cement obtained from a variety of previous operations used to drill and complete the well.

Abstract: A method includes collecting data for a borehole, designing an integrated wellbore isolation plan, the integrated wellbore isolation plan including a drilling plan and a cementing plan for the borehole, and setting zonal isolation parameters for the borehole based on the integrated wellbore isolation plan.
