SYSTEM AND METHODS FOR DETERMINING GEL BREAKING TIME OF THIXOTROPIC DRILLING FLUIDS
The behavior of gelled drilling fluids can be predicted with a low number of input parameters using an empirically derived equation that expresses the breakage of gelled drilling fluids as a function of the total strain applied to the gelled drilling fluids. Using correlative systems and lab-scale experiments, a predictive model correlates the various test input parameters with an anticipated time for breaking the gelled drilling fluid under known strain rate. Applying actual input parameters to the predictive model for a given well drilling operation produces a prescribed gel breaking procedure. The systems and methods disclosed herein provide an operator with accurate predictions of the time necessary' to break a given gelled drilling fluid. The models and methods disclosed herein can be incorporated into a control system so the drilling rig can automatically adjust its operation to most effectively break the gelled drilling fluid following a pump-off event.
