Abstract

An embodiment of a method of drilling a secondary borehole from a primary borehole includes deploying a drilling assembly at a selected location in the primary borehole in an earth formation, and operating the drilling assembly and a drill bit to form an exit trough in a borehole wall. Operating includes controlling one or more operational parameters including at least a rate of lateral penetration of the drill bit into the formation as a function of time during formation of the exit trough based on at least one of a mathematical model and measurement data collected from one or more sensors, and in response to determining that the exit trough has exited the primary borehole, drilling the secondary borehole away from the primary borehole.
