Abstract
Systems and methods for optimizing drilling results may be based on, inter alia, (1) real-time data collected during drilling, (2) a transiently modeled cuttings distribution along the wellbore, and optionally (3) a theoretical change to one or more operational parameters. In some instances, methods may include drilling a wellbore penetrating a subterranean formation while circulating a drilling fluid; gathering real-time data about the drilling; calculating a cuttings distribution along the wellbore based on the real-time data using a transient model; calculating an equivalent circulating density profile along the wellbore based on (1) real-time data collected during drilling, (2) a transiently modeled cuttings distribution along the wellbore, and optionally (3) a theoretical change; and changing at least one operational parameter based on a comparison of the equivalent circulating density profile to a fracture gradient of the subterranean formation.
