摘要： A steering augmenter for a steering device of a drilling tool, including a body, a first flow passage in the body and configured to convey a fluid supply. a channel at the outside surface of the body, the channel being configured to produce a Bernoulli effect therein during fluid flow therein, a second flow passage fluidly connecting the first flow passage to the channel, and a valve associated with the second flow passage and configured to allow, prevent or choke flow through the second flow passage. A downhole drill bit assembly including a steering augmenter, the drill bit attached to the steering augmenter. A method for drilling a borehole into the earth, the method including conveying the steering device into the borehole, operating the valve to allow, prevent or choke flow through the second flow passage, creating a steering force at the steering augmenter by the produced Bernoulli effect.

摘要： A downhole motor, having a body having an outside surface and a longitudinal extent, a first flow passage defined within the body and disposed along the longitudinal extent of the body, and a second flow passage extending from the first flow passage to a channel at the outside surface, wherein a Bernoulli suction force is created at the channel. A method for drilling a borehole, including directing a fluid through a first flow passage defined within a body of a drill and disposed along the longitudinal extent of the body, directing a portion of the fluid from the first flow passage through a second flow passage to a channel at an outside surface to create a Bernoulli suction force at the channel, and drilling a curved section of the borehole by using the Bernoulli suction force at the channel.

摘要： Methods, systems, devices, and products for downhole operations. Embodiments include downhole tools comprising an outer member configured for conveyance in the borehole; a pressure barrel positioned inside the outer member; a substantially cylindrical pod positioned inside the pressure barrel; and at least one downhole electronic component mounted between the exterior surface and the frame. The pod comprises at least one rigid outer surface forming an exterior surface of the pod and supported by a central frame extending across a diameter of the pod, such as a plurality of outer rigid surfaces. The pod may include a plurality of coupled rigid elongated semicircular metallic shells, wherein each shell of the plurality comprises a rigid outer surface of the plurality of outer rigid surfaces. Each of the at least one downhole electronic component may be sealingly enclosed within a corresponding shell.

摘要： A drilling system configured to drill a borehole into a subsurface formation, including a steering device. The steering device is configured to convey a fluid supply through a valve to an outside surface of the steering device, wherein the fluid flow causes a steering force on the steering device. A method for drilling a borehole into a subsurface formation, including disposing a steering device in the borehole, rotating the steering device, urging a fluid to flow through a valve of the steering device to an outside surface of the steering device, wherein the fluid flow causes a steering force on the steering device.
