Abstract

A method may include drilling a portion of a borehole with a bottomhole assembly (BHA) including the downhole tool in an automated drilling routine. A method may include receiving, at a control unit of the BHA, a disengagement downlink communication having a disengagement magnitude and disengagement duration. A method may include, based at least partially on the disengagement downlink communication, disengaging the automated drilling routine.

Claims (15)

1 . A method of controlling a downhole tool, the method comprising:

drilling a portion of a borehole with a bottomhole assembly (BHA) including the downhole tool in an automated drilling routine, wherein a downhole drill state (DHDS) of the downhole tool is set to a first value;

receiving, at a control unit of the BHA, at least one drilling mechanic, wherein the at least one drilling mechanic is a lower torquer RPM; and

based at least partially on the at least one drilling mechanic, transmitting instructions from the control unit to the downhole tool to set the DHDS to a second value.

2 . The method of claim 1 , wherein the first value of the DHDS is a drilling state and based at least partially on the at least one drilling mechanic, the second value is a reaming state.

3 . A method of controlling a downhole tool, the method comprising:

drilling a portion of a borehole with a bottomhole assembly (BHA) including the downhole tool in an automated drilling routine, wherein a downhole drill state (DHDS) of the downhole tool is set to a first value;

receiving, at a control unit of the BHA, at least one drilling mechanic, wherein the at least one drilling mechanic is a pulse width modulation (PWM); and

based at least partially on the at least one drilling mechanic, transmitting instructions from the control unit to the downhole tool to set the DHDS to a second value.

4 . The method of claim 3 , wherein the first value of the DHDS is a drilling state and based at least partially on the at least one drilling mechanic, the second value is a reaming state.

5 . A method of controlling a downhole tool, the method comprising:

drilling a portion of a borehole with a bottomhole assembly (BHA) including the downhole tool in an automated drilling routine, wherein a downhole drill state (DHDS) of the downhole tool is set to a first value;

receiving, at a control unit of the BHA, at least one drilling mechanic, wherein the at least one drilling mechanic is a ratio of lower torquer flow rate relative to a drill string flow rate; and

based at least partially on the at least one drilling mechanic, transmitting instructions from the control unit to the downhole tool to set the DHDS to a second value.

6 . The method of claim 5 , wherein the first value of the DHDS is a drilling state and based at least partially on the at least one drilling mechanic, the second value is a reaming state.
