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.

Controlling a coiled tubing unit at a well site

According to one embodiment of the present disclosure, a computer-implemented method for controlling a coiled tubing unit at a well site is provided. The method includes receiving, by a processing device, wellbore data. The method further includes generating, by the processing device, an automated coiled tubing control plan for the coiled tubing unit based at least in part on the wellbore data. The method further includes controlling, by the processing device, the coiled tubing unit using the automated coiled tubing control plan to cause coiled tubing to run into a wellbore at the well site to a target depth, wait a waiting period of time, and cause the coiled tubing to run out of the wellbore.

A wellbore system may include a work string and at least one downhole device connected to a portion of the work string, the downhole device configured to deliver a periodic stream of fluid to a portion of a wellbore. The system may further include at least one sensor configured to detect reflected energy pulses associated with the periodic stream of fluid. The at least one downhole device may be configured to modify a pressure of the periodic stream of fluid in real time based on the reflected energy pulses received in real time.

A downhole system () includes a tubular () having a longitudinal axis (), and a trace () applied on the tubular (). The trace () includes a conductive portion () formed from an electrically conductive material () and the trace () is configured to deliver a signal between uphole and downhole locations of the tubular ().

An injector control system for a coiled tubing unit includes a programmable logic controller arranged to receive a signal related to sensed parameters of a coiled tubing injection operation; a traction pressure control hydraulic circuit operable to adjust hydraulic pressure provided to at least one traction cylinder in a coiled tubing injection head; a motor pressure control hydraulic circuit operable to adjust hydraulic pressure provided to at least one motor of the coiled tubing injection head; and at least one of the traction pressure control hydraulic circuit and the motor pressure control hydraulic circuit including a proportional control valve in receipt of a variable electrical signal from the programmable logic controller. The programmable logic controller adjusts the signal delivered to the proportional control valve throughout the coiled tubing injection operation as dictated by the sensed parameters.
