Abstract
Systems, apparatuses, and methods for calculating twist stored in a drill string during rotary drilling to determine a target oscillation amount for oscillating the drill string during slide drilling. Rotary drilling a wellbore using a top drive imparts a rotational displacement on, and stored in, the drill string. After stopping the rotary drilling, the rotational displacement stored in the drill string is released such that a free reverse rotation is experienced by the top drive as the drill string untwists. A sensor associated with the top drive collects data associated with the free reverse rotation of the drill string. Using the data, the rotational displacement stored in the drill string is calculated, and based on the calculated rotational displacement, a target oscillation amount is determined. During slide drilling, the top drive oscillates the drill string based on the oscillation amount to reduce friction in the wellbore without changing direction.
