E21B 19/22
E21B 17/20
E21B 44/06

Abstract:

A system is provided including a coiled tubing reel apparatus including a reel drum for storing a coiled tubing string spooled on the reel drum and a hydraulic reel drive motor that controls rotation of the reel drum. The system further includes a reel controller that determines an estimated reel back tension for a portion of the coiled tubing string between the reel apparatus and the injector based on a set of parameters related to a coiled tubing operation. The reel controller determines a target reel back tension to be applied to the portion of the coiled tubing string by adjusting the estimated reel back tension based on a historical job dataset. The reel controller then determines and sets a target hydraulic pressure of the reel drive motor to achieve the target reel back tension in the portion of the coiled tubing string.

International Classification:

E21B 47/13

Abstract:

An electromagnetic telemetry (EMT) system is provided. A downhole transceiver sub is coupled with a downhole tool. The downhole transceiver sub and the downhole tool positioned in a wellbore having a casing extending along a length of the wellbore. The downhole transceiver sub transmits data from the downhole tool by passing a current through the casing to radiate electromagnetic fields. An uphole transceiver sub is disposed uphole from the downhole transceiver sub. The uphole transceiver sub is operable to measure the electromagnetic fields. The measured electromagnetic fields are decoded to obtain the data from the downhole tool.
