Abstract: A transportable blending system includes a container enclosure including a base, a roof, opposing first and second ends, and opposing first and second sidewalls, a pump fluidly coupled to an inlet manifold penetrating the container enclosure, wherein a base fluid is conveyed to the pump via the inlet manifold, and a mixing unit in fluid communication with the pump to receive the base fluid. A hopper is fluidly coupled to the mixing unit and has an inlet aligned with an opening defined in the roof, wherein an additive is delivered to the hopper via the opening to be conveyed to the mixing unit and blended with the base fluid to generate a working fluid.

Abstract: A corrosion sensor (1), adapted to determine the presence of corrosion in a material having at least one layer of a coating material on a surface thereof, is disclosed. The corrosion sensor (1) comprises a microwave transceiver (2); and a waveguide (3), with the waveguide (3) being operably coupled to the microwave transceiver (2). The microwave transceiver (2) transmits a first continuous wave microwave signal incident on the at least one layer and receives a second continuous wave microwave signal reflected from the at least one layer. The first and second continuous wave signals are combined into an intermediate continuous wave microwave signal having a phase difference indicative of corrosion in the material. Both the first and second continuous wave microwave signals are frequency modulated continuous wave signals. A method of sensing corrosion, a system for sensing corrosion and the use of a microwave transceiver to sense corrosion are also disclosed.

Abstract: A sensor comprising: a dielectric waveguide for guiding a microwave signal; and a dielectric reflector at an end of the dielectric waveguide to cause formation of a sensing field beyond an outer surface of the dielectric reflector.

Abstract: Radial penetrator assembly 10 conducts fluid through the passageway in the wall to a wellhead housing 18 and into a port in a tubular hanger 14 positioned within a central bore 19 in the wellhead housing. The flexible tube 22 extends between the passageway in the wellhead housing and the port in the inner member, while sleeve-shaped adapter 30 extends radially from the wellhead housing and has an adapter bore sealed to a radial passageway in the wellhead housing. A radial outer seal 64 seals between the radial outer portion of the adapter 30 and a radially outer portion of the flexible tube 22. The flexibility of the tube permits an inner portion axis with the tube to be offset or slanted with respect to an outer portion axis of the tube.
