Abstract
A downhole tool may store a well plan on a hardware storage device of a downhole tool. A downhole tool may drill a first portion of a borehole according to a first stage of the well plan with the downhole tool. A downhole tool may change at least one of a dogleg severity (DLS) and a rate of penetration (ROP) of the downhole tool based on a second stage of the well plan stored on the hardware storage device. A downhole tool may drill a second portion of the borehole according to the second stage of the well plan.
Claims17
A method of controlling a downhole tool, the method comprising:
- storing a well plan on a hardware storage device of a downhole tool, wherein the well plan includes a plurality of stages;
- drilling with the downhole tool a first portion of a borehole according to a first stage of the well plan, wherein the first stage belongs to the plurality of stages of the well plan stored on the hardware storage device of the downhole tool;
- selecting a second stage of the well plan in response to receiving a single downlink communication, wherein the second stage belongs to the plurality of stages of the well plan stored on the hardware storage device of the downhole tool;
- setting at least one of a dogleg severity (DLS) and a rate of penetration (ROP) of the downhole tool based on the selected second stage of the well plan stored on the hardware storage device;
- and
- drilling a second portion of the borehole according to the selected second stage of the well plan.
A method of controlling a downhole tool, the method comprising:
- storing a well plan on a hardware storage device of a downhole tool, wherein the well plan includes a plurality of stages and a first trigger indicating a transition from a first stage to a second stage of the plurality of stages;
- drilling with the downhole tool a first portion of a borehole according to a first stage of the well plan, wherein the first stage belongs to the plurality of stages of the well plan stored on the hardware storage device of the downhole tool;
- setting target azimuth and target inclination of the downhole tool based on detection of the first trigger of the well plan and the second stage of the well plan stored on the hardware storage device;
- and
- drilling a second portion of the borehole according to the second stage of the well plan.
