TL;DR: In this paper, an uphole control device is configured to transmit a reference trajectory to the downhole control devices and receive information about an actual trajectory from the down hole control device.

TL;DR: In this article, a method for drilling operation in a subterranean formation, including calculating, by a hardware processor and in response to determining that an magnitude of gyro data representing rotations of a drill bit in a bottom hole assembly (BHA) and a time derivative of the gyrodata are within a pre-determined range, a drift parameter of the data, analyzing, by the hardware processor, the Gyro data based on the drift parameter to generate a stick slip alert, and presenting the stick-slip alert.

TL;DR: In this paper, the foreliggende oppfinnelse tilveiebringer apparat og fremgangsmate for retningsboring is presented, which is a utformet for a: overfore en referansebane til nedhullsstyreanordningen og motta informasjon vedrorende en virkelig bane.
