Abstract (en)
[origin: WO2022133484A1] Methods, computing systems, and computer-readable media for dynamically adjusting drilling parameters during a drilling operation. The approach involves receiving, in real time, drilling parameter measurements and response measurements during a drilling operation. If the response measurements are below the lower limit of a window or trending downwards, the approach determines a new drilling parameter value that will increase the response measurement. The approach dynamically adjusts the drilling parameter value above the sectional limit, while still respecting hard limits. When the measured value improves, the approach returns the limit for the drilling parameter to the sectional limit.
