Abstract
A method for controlling a coiled tubing unit at a well site having a wellbore that extends downhole from a surface of the well site is provided. The method includes creating a coiled tubing simulation for performing a coiled tubing operation. The method further includes receiving wellbore data. The wellbore data includes downhole data collected using a downhole sensor downhole in the wellbore, and the downhole data includes a differential pressure measurement. The method further includes generating an automated coiled tubing control plan for the coiled tubing unit based at least in part on the wellbore data and the coiled tubing simulation. The method further includes controlling the coiled tubing unit using the automated coiled tubing control plan to regulate at least one of a rate-of-penetration of the coiled tubing unit or a weight-on-bit of the coiled tubing unit based at least in part on the differential pressure measurement.
