Abstract
A system may obtain azimuth and inclination measurements from a downhole tool in a downhole environment. A system may obtain a downhole ROP and downhole DLS from a downhole control unit. A system may determine a corrected DLS demand based at least partially on a ratio of downhole ROP and surface ROP. A system may transmit a DLS demand setting to the downhole tool based at least partially on the corrected DLS demand and the downhole ROP. A system may drill at least a portion of a borehole with the downhole tool based at least partially on the corrected DLS demand.
Claims10
A method of controlling a downhole tool, the method comprising:
- obtaining azimuth and inclination measurements of a borehole from the downhole tool in the borehole;
- obtaining a downhole rate of penetration (ROP) and a downhole dogleg severity (DLS) from a downhole control unit of the downhole tool, wherein the downhole DLS is determined based on measured changes in the azimuth and inclination measurements over time relative to the downhole ROP;
- determining a ratio of the downhole ROP to a surface ROP, wherein the surface ROP is a measurement at surface of advancement of the downhole tool;
- determining a DLS demand based at least partially on the downhole DLS and the ratio of the downhole ROP to the surface ROP;
- transmitting a DLS demand setting to the downhole tool based at least partially on the DLS demand;
- and
- drilling at least a portion of the borehole with the downhole tool based at least partially on the DLS demand.
