Abstract
The present disclosure provides systems and methods for tracking system parameters in each of two or more circulatory systems, such as in a dual gradient drilling system. The systems and methods may include defining each of multiple circulatory systems and simultaneously tracking one or more system parameters for each circulatory system. Systems and methods may further include tracking a discrete portion of fluid circulating in each circulatory system, and associating one or more system parameters with each tracked discrete portion of fluid. Such association may be maintained as each portion of fluid circulates in each respective circulatory system.
