Summary:A drill bit is provided that in one embodiment may include a force application device on a drill bit body, wherein the force application device includes a force application member pivotally coupled to the drill bit and configured to extend from the drill bit body to apply force on a wellbore wall when the drill bit is used to drill a wellbore, and an actuator configured to actuate the force application member to apply force on a wellbore wall during drilling of the wellbore. La présente invention a trait à un trépan qui selon un mode de réalisation peut inclure un dispositif d'application de force sur un corps de trépan, lequel dispositif d'application de force inclut un élément d'application de force couplé de façon pivotante au trépan et configuré pour s'étendre depuis le corps de trépan afin d'appliquer une force sur la paroi d'un puits lorsque le trépan est utilisé pour forer un puits, et un organe de commande configuré pour actionner l'élément d'application de force afin d'appliquer une force sur la paroi d'un puits au cours du forage du puits.
