Abstract: Multiple wires run parallel to one another. Each of wires is spaced apart from each adjacent wire at a distance less than a width of an encased microchip. Each of the plurality of wires includes a plurality of straight segments in a plane and bent segments that connect two of the plurality of straight segments. For each of the wires, each bent segments includes a first end, a second end, and a curved portion curved away from the plane. The first end is connected to at least one of the straight segments and separated from the second end a distance greater than the width of the encased microchip. The curved portion includes a diameter greater than the width of the encased microchip.

Abstract: Systems and methods for reducing friction between a casing string and a bore of a subterranean well when moving the casing string within the bore of a subterranean well include a roller bearing assembly. The roller bearing assembly has a bearing body and a plurality of spherical bearings spaced around an outer diameter of the bearing body. The bearing body is sized to be removably attached to an outer diameter of the casing string and to be stationary relative to the casing string.

Abstract: A system and method for sealing around a fluid flow member includes a ram closing assembly. The ram closing assembly has a sealing chamber having a generally cylindrical shape when the ram closing assembly is in a closed position. A ram assembly is located at an end of the sealing chamber. The ram assembly has a pair of rams, each ram having an engaging surface, the engaging surface sized and shaped to seal around the fluid flow member. The ram assembly also has an actuating arm assembly connected to one of the rams and a ram body. The pair of rams is rotationally attached to the ram body.

Abstract: A system and method for covering a cellar at a wellhead to prevent and control fluids and gases from the cellar. The covering includes a mat that circumscribes a wellhead tubular that projects upward from the cellar. A split seam in the mat extends radially from the opening to the mat outer periphery which allows the mat to be placed around the wellhead tubular. A fastener joins the ends of the mat that meet at the split seam. The mat includes a collar, which mounts to the mat along the opening and extends axially away from an upper surface of the mat. The collar is secured to the wellhead tabular with a strap. Two discharge lines project through the mat into the cellar, one for pumping into the cellar, and one for withdrawing fluid that has collected in the cellar.
