A dual gradient cementing system is modeled in a modeled subsea wellbore. The modeled dual gradient cementing system comprises a plurality of components including a mud lift pump (MLP) coupling a subsea rotating device (SRD) to a surface mud return line, wherein the MLP is located at a subsea depth and the SRD diverts annular fluids from an annulus away from a riser. The modeled dual gradient cementing system is simulated in operation, wherein a fluid loss value of% at the subsea depth of the MLP is assumed, and a fluid property of a simulated non-static fluid in the simulated dual gradient cementing system while in operation is estimated. Thereafter, an actual dual gradient cementing operation is performed in an actual subsea wellbore, wherein an actual non-static fluid corresponding to the simulated non-static fluid exhibits the fluid property.
