Abstract
In at least one embodiment, a control system may include a processor coupled to the database. The control system may include a memory accessible to the processor and storing instructions executable by the processor for: during slide drilling, detecting an increase to a first differential pressure (ΔP) that is greater than a first threshold pressure. In at least one embodiment, the control system may responsive to detecting the first ΔP, determining a time duration for which the first ΔP exceeds the first threshold pressure. In at least one embodiment, the control system may responsive to the first ΔP exceeding the first threshold pressure for less than a first threshold time, continuing the slide drilling without modifying a drilling parameter.
