A drilling system for drilling a wellbore that includes a drill string rotatable in a first direction. The system also includes a bottom hole assembly (BHA) that includes: a drill bit, a housing with a bore, a first fluid-driven motor in fluid communication with the bore and connected with and configured to rotate a portion of the BHA in a second direction opposite the first direction, a second fluid-driven motor in fluid communication with the bore and connected with and configured to rotate the drill bit, a valve in fluid communication with a vent including a flow path arranged to direct fluid away from any one or both of the fluid-driven motors, and a controller in communication with and configured to adjust a drilling parameter of the BHA by controlling the valve to adjust a flow rate of the fluid output from the valve into the vent.
