FILLING SYSTEM SUITABLE FOR SOLID DRAG REDUCING AGENT AND SOLID THICKENER
The present invention provides a filling system suitable for a solid drag reducing agent and a solid thickener. The system comprises a raw material storage device, a raw material conveying device, a weight metering device, a feeding funnel, and a disperser. The above-mentioned system controls the feeding speed through the raw material conveying device and the weight metering device, and uses the feeding funnel and the disperser to achieve uniform dispersion of the raw material and water, and finally realizes online filling of the raw material.
TRANSPORTING BITUMEN FROTH HAVING COARSE SOLIDS THROUGH A PIPELINE
A method for transporting a bitumen froth having coarse solids having a particle size>180 m through a pipeline is provided comprising injecting into the pipeline a bitumen froth slug having a lower temperature or a lower water content or both that the bitumen froth.

Mobile zipper unit
An apparatus to distribute pressurized fluid from one or more sources to multiple wellbores. The apparatus includes a manifold having at least two inlets and at least two outlets. Pressurized fluid is brought into the manifold from opposing directions so that the fluid from one inlet will impinge upon the fluid from the other inlet thereby deenergizing the fluid. Additionally, the manifold is configured such that the cross-sectional area of the inlets is less than the cross-sectional area of the manifold thereby decreasing velocity minimizing the kinetic energy available to erode or otherwise damage equipment, while providing a pressure decrease as the fluid enters the manifold. The outlets are configured such that the cross-sectional area of the outlets providing fluid to a single wellbore is greater than or equal to the cross-sectional area of the inlets such that no pressure increase occurs within the manifold or the outlets as the fluid exits the manifold. Additional velocity reduction enhancements may include angled or camp third turns between the inlet and the manifold or the manifold and an outlet.
WAX INHIBITORS FOR OIL COMPOSITIONS AND METHODS OF USING WAX INHIBITORS TO REDUCE WAX DEPOSITION FROM OIL
An oil composition includes an oil and an effective amount of a wax inhibitor that includes at least one modified alpha-olefin maleic anhydride copolymer of the formula:
##STR00001##
wherein R1 is selected from hydrogen or hydrocarbyl groups containing 12-60 carbon atoms and an average carbon atom number of R1, if not hydrogen, in the copolymer is in a range from 20 to 32, R2 is selected from hydrocarbyl groups containing 6-12 carbon atoms, and n is a number of repeating units ranging from 1 to 100.
CONTROLLING FLOW OF BLACK POWDER IN HYDROCARBON PIPELINES
Black powder flowing with hydrocarbons in a hydrocarbon pipeline is converted into a magnetorheological slurry by implementing wet scrubbing in the hydrocarbon pipeline. A flow of the magnetorheological slurry through the hydrocarbon pipeline is controlled.

DRAG REDUCTION OF ASPHALTENIC CRUDE OILS
The process begins by obtaining a first batch of monomers selected from a group of acrylates with a molecular weight equal to or less than butyl acrylate and/or methacrylate with a molecular weight equal to or less than butyl methacrylate. A second batch of monomers is then selected from a group of acrylates with a molecular weight greater than butyl acrylate and/or methacrylate with a molecular weight greater than butyl methacrylate. A mixture is then prepared by mixing the first batch of monomers and the second batch of monomers, wherein the second batch of monomers are greater than 50% by weight of the mixture. Finally, the mixture is polymerized to produce a drag reducing polymer. The drag reducing polymer is capable of imparting drag reducing properties in liquid hydrocarbons.
