A method of manufacturing a base pipe for use in horizontal well completion, the method includes wrapping an inner shroud around a base pipe, the inner shroud is disconnected from the base pipe and forms seams along each edge of the inner shroud; fusing the seams together; allowing the inner shroud to cool, the inner shroud shrinks around the base pipe to form a friction lock between the base pipe and the inner shroud; laying a filter medium onto an outer shroud, wherein the filter medium is disconnected from the outer shroud, thereby creating a mesh filter medium/outer shroud sheet; wrapping filter medium/outer shroud sheet around the inner shroud, the filter medium is positioned between the inner shroud and outer shroud, thereby creating a second set of seams; and fusing the second set of seams together, thereby creating a second friction lock between the outer shroud and the inner shroud.

Removable trap stations for hydrocarbon flowlines can be implemented as an apparatus. The apparatus includes a multi-phase fluid receiver body and a tank defining an interior volume. The fluid receiver body is configured to couple to a flowline carrying a multi-phase fluid including solids and liquids. The fluid receiver body includes an inlet portion configured to receive a portion of the multi-phase fluid including a portion of the solids flowing through the flowline into the receiver body. The fluid receiver body includes an outlet portion fluidically coupled to the inlet portion. The portion of the multi-phase fluid is configured to flow from the inlet portion to the outlet portion. The tank is fluidically and detachably coupled to the outlet and is configured to receive and retain the portion of the multi-phase fluid received through the inlet portion.

A process and device to create access to low gravity solids (LGS) of about 2 to 20 microns for removal from a fluid material/LGS emulsion having the steps of: flowing the emulsion into high pressure tubing; separating the emulsion into at least two high pressure streams; forcing the emulsion through high pressure nozzles at a terminus of each of the at least two high pressure tubing streams at a speed in the range of about 10 ft/sec to 200 ft/sec or at a force in a range of about 10 to 100 PSI; and colliding the streams of emulsion exiting the high pressure nozzle within a pressure drop chamber, wherein the pressure drop is in a range of about 5% to 50% of the back pressure of the nozzles; wherein a cavitation effect is realized from a collision force of the high pressure streams within the pressure drop chamber.

A tank system may be conventional and fixed, or mobile, such as a fracking fluid or other tank trailer. A drain port thereof is fitted with an adapter connecting a snorkel system to drain liquids from near the top of the liquid level in the tank. A snorkel head at the extreme distal end of a tube near the longitudinal center of the tank is suspended by a system of buoys. A flow field controller resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently without entrainment of overlying gases and vapors, nor the second liquid layered therebelow. All are configured to fit into the tank without requiring any personnel to enter the tank. Oil, water, and sludge may drain through the system to exit the tank.

A separator is provided for removing hydrocarbons and fluid from solids from a slurry. The separator includes a first separator tank for receiving a slurry of fluid and solids contaminated with hydrocarbons, said first separator tank comprising agitating means for agitating hydrocarbons to separate from the slurry and rise as foam and comprising a lower end to collect the solids; a first centrifuge in communication with the lower end of the first separator tank to receive and centrifuge the solids to further remove hydrocarbons therefrom, said first centrifuge comprising a fluid return to return fluids to the first separator tank; a second separator tank for receiving solids from the first centrifuge, said second separator tank comprising agitator means for agitating hydrocarbons to separate from the slurry and rise as foam and comprising a lower end to collect solids; a second centrifuge in communication with the lower end of the second separator tank to receive and centrifuge the solids to further remove hydrocarbons therefrom, said second centrifuge comprising a fluid return to return fluids to the second separator tank; and one or more settling tanks connected in series with each of said first and second separator tanks for further separation of hydrocarbons from fluid. Solids exiting the first and second centrifuges are at least 99% free of hydrocarbons.

An intelligent magnetic microfluidic concentrator employs a technique of feeding ores circumferentially and allowing tailings to overflow centrally upward. The intelligent magnetic microfluidic concentrator comprises a sorting system consisting of an ore feeding chute, an overflow chute, an overflow tank, a sorting tank, and a magnetic system, the overflow tank is disposed at an upper portion of the sorting tank, the ore feeding chute is disposed at the top of the overflow tank, the ore feeding chute feeds an ore slurry to the upper portion of the sorting tank circumferentially along an inner wall of the sorting tank, and the tailings overflow out upward from the overflow tank disposed centrally and located at the upper half portion of the sorting tank. A magnetic microfluidic concentrator and a complete set of beneficiation equipment are also provided.

A dual-stage sand and gas separator for use within a wellbore of a fluid producing well is disclosed. During sand separation, fluid is ported into a vortex housing and across a vortex cup which imparts a vortex motion on the fluid to separate solids from the fluid. Some of the solids are filtered by a sand filter screen, while heavier solids are diverted down hole by a diverter plate. The fluid pass internally through the vortex cup into the gas separation housing. During the gas separation phase, a sump is created by the transfer tubing and gas is separated from the fluid and ported away from the tubing.
