An Binh Ho

A system and method for drilling are provided. The method may comprise receiving well plan and BHA information; determining the BHA is approaching a first zone in which a first slide drilling operation is to occur; and receiving first zone characteristics. The method may further comprise determining an on bottom time to orient the BHA in the first zone; determining an additional time for the first slide drilling operation; and determining an off bottom time to orient the BHA prior to reaching the first zone. The method may further comprise comparing the additional time for the first slide drilling operation in the first zone to the off bottom time to orient the BHA prior to reaching the first zone, and sending one or more control signals to orient the BHA either prior to reaching or at the first zone based at least in part on the comparison.

Apparatus and methods for automated slide drilling

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.

Apparatus and methods for uninterrupted drilling

An automated slide drilling system (ASDS) may be used with a drilling rig system to control slide drilling. The ASDS may autonomously control slide drilling without user input during the slide drilling. The ASDS may further support a transition from rotary drilling to slide drilling to rotary drilling without user input during the transitions. The ASDS may also support user input and user notifications for various steps to enable manual or semi-manual control of slide drilling by a driller or an operator.

Apparatus for automated slide drilling

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 (&#x394;P) that is greater than a first threshold pressure. In at least one embodiment, the control system may responsive to detecting the first &#x394;P, determining a time duration for which the first &#x394;P exceeds the first threshold pressure. In at least one embodiment, the control system may responsive to the first &#x394;P exceeding the first threshold pressure for less than a first threshold time, continuing the slide drilling without modifying a drilling parameter.

During slide drilling, certain transient variances in differential pressure may indicate that a subsequent and temporary variance in a toolface angle error does not indicate that drilling should be interrupted. The transient variances in the differential pressure may be within a range of particular threshold pressures.
