Abstract: This disclosure presents methods and systems for positioning a magnetic fluid conditioner in a well. One or more magnetic fluid conditioners are attached to a coupling mandrel operable to engage with the tubing of a well, either with an existing completion component or directly with the tubing. The coupling mandrel includes a locking mechanism, such as keys or dogs, for setting the mandrel to the profile nipple. The coupling mandrel further includes a packing stack or an expandable element that seals with the completion component or the tubing. The seal directs oil through the mandrel and thus, through the magnetic fluid conditioners. In some embodiments, multiple magnetic fluid conditioners are attached in tandem for more effective conditioning operations. The magnetic fluid conditioners can condition the oil to inhibit the formation of paraffin therein.

Abstract: Fluid communication may be improved for an ethmoid sinus by installing a port or wick in the wall of the ethmoid sinus to provide a fluid passageway across the wall of the ethmoid sinus. Fluid communication for an ethmoid sinus may also be improved by inflating a balloon in a retrobullar space, remodeling the posterior wall of the ethmoid bulla to expand the transition area in the retrobullar space. In addition, a wall defining the retrobullar space may be pierced to provide a passageway for fluid communication.

Abstract: An endoscope comprises an elongate shaft assembly, a window, a viewing angle adjustment assembly, and an indicator feature. The window is located at the distal end of the shaft assembly. The shaft assembly is configured to transmit a view acquired through the window. The viewing angle adjustment assembly is operable to selectively change a viewing angle associated with the window. The indicator feature is positioned to be visible within a view acquired through the window. The indicator feature is configured to indicate the viewing angle associated with the window.

Abstract: An exemplary apparatus for removing metallic debris from a drilling fluid is provided that includes a first end member, a second end member, and one or more elongated members extending between the first end member and the second end member. The elongated members may each include at least one magnet. Drilling fluid may flow past the elongated members, which may be located in a drilling fluid cleansing machine such as a shale shaker, so that metallic debris in the drilling fluid, if any exist, are attracted by the magnets in the elongated members. Some of the metallic debris may adhere to an exterior surface of the elongated members so that the metallic debris are removed from the drilling fluid. The metallic debris can then be removed from the exterior surface of the elongated members.

Abstract: A magnetic water conditioner treats water with a magnetic field. The magnetic water conditioner includes a tank having an inlet operable to receive water from a pump and an outlet operable to discharge the water. The magnetic water conditioner is installed in close proximity to the pump. A plurality of permanent magnet members are aligned and spaced apart in the interior of the tank with north and south poles disposed at opposite sides of the permanent magnet members. The water flows through the gaps between the permanent magnet members, thus being subjected to magnetic fields created by the permanent magnet members.
