Abstract: A production well includes a casing and encapsulated tubing positioned within the casing. The encapsulated tubing includes a conductive sidewall defining a channel for an injection fluid. The production well further includes an insulative layer surrounding the conductive sidewall. The production well also includes a controller configured to regulate flow of an electrical current through the conductive sidewall. The production well further includes production tubing positioned within the casing and configured to channel a production fluid through the casing. The insulative layer is configured to inhibit transmission of the electrical current between the conductive sidewall and the production tubing. The production well also includes at least one sensor positioned within the casing to detect downhole conditions of the production well. The conductive sidewall is configured to conduct electrical current toward the at least one sensor.

Abstract: To alleviate the problems that exist in the current state of the art, this invention provides a beekeeper's veil with an opening directly over and in front of the face of the wearer, providing fast, easy access through the veil with out the risk or fears mentioned above. The zipper used to open/close the face-covering panel is preferably visible to the beekeeper so that they do not have to rely on “feel” or mirrors. The head-covering portion of the veil does not have to be lifted over the head, but instead opens directly over the face, making it easy to quickly drink water, wipe sweat from the eyes, or smoke a cigarette. This also allows individuals not familiar with beekeeping to lose precious time attempting to give aid.

Abstract: A method for detecting the presence of precipitants in a hydrocarbon stream, the method comprising introducing at least a portion of the hydrocarbon stream into a measurement chamber of an NMR measuring device, assaying the fluids in the chamber with proton nuclear magnetic resonance to obtain NMR signals, and processing the NMR signals to detect the formation of precipitants in the hydrocarbon stream. The method may be carried out at first and second locations, and NMR signals obtained at the two locations compared to detect precipitation of precipitant between the two locations. A method of monitoring the water content of a hydrocarbon stream in a flowline comprising introducing at least a portion of the hydrocarbon stream into an NMR measuring device, measuring a baseline NMR water signal of the hydrocarbon stream and comparing subsequent NMR water signals with the baseline NMR water signal to detect changes in the water content of the hydrocarbon stream.

Abstract: In systems and methods for production of hydrocarbons fluids from a formation surrounding a wellbore, a production assembly is cemented into place, and excess cement is then cleaned from the production tubing and liner. Thereafter, hydrocarbon fluids are produced and artificial gas lift assistance is provided. All of this may be accomplished in a single trip (mono-trip) of the production tubing.

Abstract: A general method for the design of structures composed of permanent magnetic material for producing and modifying magnetic fields. The method employs a finite set of permissible spatial harmonic modes upon a surface. In particular, it has applications where the structures are finite and open, for which an exact solution is not possible. The method determines an optimum distribution based upon a least squares minimization of the difference between the achievable and desired field within a Region Of Interest (ROI). The method also has application in passively improving the homogeneity of existing magnetic fields (shimming) by distributing magnetic materials in the vicinity of the ROI.

Abstract: A method of and apparatus for reducing ghost artifact in image data are disclosed, for use with a Magnetic Resonance Imaging apparatus in which one or more coherent ghost artifacts occur in the image. The apparatus comprises means for converting the sampled data into the image data, and means for analysing the sampled data to determined a correction to reduce the ghost artifact. The method of the invention comprises analysing the sampled data to determine a correction to reduce the ghost artifact.

Abstract: The invention describes apparatus for, and a method of, active acoustic screening and combined active acoustic and magnetic screening, of magnetic field coils, which pass a time varying current and which reside in relatively high static magnetic fields, typically greater than about 0.1 T. The invention is particularly well suited for acoustic screening of magnetic field gradient coils used in Magnetic Resonance Imaging (MRI). In a preferred embodiment a closed loop carrying current is arranged such that two different parts of the loop are mechanically coupled, dimensioned and arranged with respect to one another such that Lorentz forces experienced by the magnetic equipment are substantially reduced and preferably cancelled.In a different embodiment the invention is modified so as to permit simultaneous magnetic and acoustic screening.
