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.

Systems and methods for automatically adapting operation of an electric drive system for an electric submersible pump (ESP). A control system for an electric drive receives live measurements of operating conditions of the ESP as the ESP is operating. The control system calculates adjustments to settings of the electric drive which generates output power that drives the ESP, where the adjustments are calculated based at least in part on the live measurements, and without user intervention. The control system thereby automatically controls the drive to modify the output power provided to the ESP, which in turn controls the operation of the ESP. The adjustments may increase the stability of the ESP's operation, improve the performance of the ESP, and adapt the ESP's operation to changing well conditions.

A control system for an electric drive receives live measurements of operating conditions of the ESP as the ESP is operating. The control system calculates adjustments to settings of the electric drive which generates output power that drives the ESP, where the adjustments are calculated based at least in part on the live measurements, and without user intervention. The control system thereby automatically controls the drive to modify the output power provided to the ESP, which in turn controls the operation of the ESP. The adjustments may increase the stability of the ESP's operation, improve the performance of the ESP, and adapt the ESP's operation to changing well conditions.
