Abstract: A pipe in pipe electric motor assembly comprising: a drilling string comprising an inner pipe and an outer pipe and an electric motor; wherein the electric motor is provided with power supplied by the inner pipe and the outer pipe acting at least as conductors and associated methods.

Abstract: An example method may include determining a first planned stimulation location within the formation. The first planned stimulation location may be based, at least in part, on a pre-determined model of a formation. A borehole in the formation may be drilled with a downhole tool. The first planned stimulation location may be adjusted based, at least in part, on data received at the downhole tool. Additionally, the downhole tool may stimulate the formation at the adjusted first planned stimulation location. A second stimulation location also may be determined based on data received at the downhole tool after stimulation of the formation at the adjusted first planned stimulation location.

Abstract: Systems and methods for optimized well creation in a shale formation are described herein. The method may include determining a first planned stimulation location within the formation. The first planned stimulation location may be based, at least in part, on a pre-determined model of a formation. A borehole in the formation may be drilled with a downhole tool. The first planned stimulation location based, at least in part, on data received at the downhole tool. Additionally, the downhole tool may stimulate the formation at the adjusted first planned stimulation location. In certain other embodiments, a second stimulation location may be determined based on data received at the downhole tool after stimulation of the formation at the adjusted first planned stimulation location.

Abstract: A device to couple to a rotatable drill pipe to control pressure of a drilling system is disclosed. The device includes an inner surface to wrap around a portion of a rotatable drill pipe and having an inner diameter. A first tapered portion is opposite a second tapered portion, with a middle portion therebetween including an outer diameter greater than the inner diameter. The first and second tapered portions each taper from the outer surface to the inner surface. The middle portion, the first tapered portion, and the second tapered portion form an outer surface to sealingly pass through a seal element of a controlled-pressure drilling system. At least a portion of the outer surface corresponding to the middle portion includes a low-friction material.
