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.

System and method to control a dual motor rotary steerable tool

A directional drilling system for use in drilling a wellbore can include a bit deflection assembly with a bit axis deflection mechanism which applies a deflecting force to a shaft connected to a drill bit. The deflecting force may deflect the shaft, without being reacted between the deflection mechanism and the drill bit. The deflecting force may deflect the shaft between the drill bit and a radial bearing which maintains the shaft centered in the bit deflection assembly. The deflection mechanism may both angularly deflect and laterally displace the bit axis in the deflection mechanism.

Directional drilling systems

An apparatus and method for force feeding air to the carburetor of an internal engine. The apparatus includes a fitting for diverting a portion of the pressurized emission control air, the fitting positioned in the hose supplying pressurized air from an air pump of an emission control system to the exhaust system of a vehicle. The diverted air, after passing through an air filter, is introduced into the interior of the carburetor air filter housing radially inwardly from the air filter element within the housing. The pressurized air then flows through the carburetor to thereby enhance uniform distribution of the air-fuel mixture to the cylinders of the engine. Because the output of the air pump varies with the speed of the engine, higher pressure air is furnished at higher speeds of the engine. The furnished air can be pre-heated to further enhance vaporization of the fuel.
