Abstract: A process of manufacturing a composition comprises a particulate drag reducing agent is disclosed. The process comprising: continuously forming a temporary container; introducing an unsaturated monomer component and a radical polymerization component into the temporary container; sealing the temporary container to form a sealed temporary container; allowing the unsaturated monomer component to polymerize in the sealed temporary container to form the drag reducing agent via a radical polymerization reaction, the drag reducing agent having a molecular weight of about 1 million gram/mol to about 50 million gram/mol; and grinding the drag reducing agent to form a composition comprising a particulate drag reducing agent, the particulate drag reducing agent having a particle size of about 1 to about 1,500 microns.

Abstract: A stabilized paraffin inhibitor/pour point depressant (PI/PPD) product formulation is described which includes a copolymer having a monomer selected from the group consisting of alkyl acrylate polymers, alkyl methacrylate polymers, and combinations thereof, where the copolymer comprises vinyl acetate and the product includes an ethylene-based copolymer. The presence of the vinyl acetate stabilizes the product to prevent or inhibit the ethylene-based copolymer from separating out of the product. The product is useful to reduce paraffin deposition and/or improve flow characteristics of petroleum fluids, such as crude oil.

Abstract: A demulsifying additive comprising a branched aliphatic compound may be introduced to a stream containing mixtures of or emulsions of oil and water in an effective amount to separate water from the oil in the stream, such as separating oil from emulsified oil-in-water and/or separating water from emulsified water-in-oil in a production fluid. The branched aliphatic compound may be grafted with a polyether via a crosslinking reaction. Alternatively, branched aliphatic compounds may be crosslinked together.

Abstract: A procedure for improved temperature control in controlled radical polymerization processes is disclosed. The procedure is directed at controlling the concentration of the persistent radical in ATRP and NMP polymerizations procedures and the concentration of radicals in a RAFT polymerization process by feeding a reducing agent or radical precursor continuously or intermittently to the reaction medium through one of more ports.

Abstract: The present disclosure is directed to additives comprising modified cationic starches that may be applied to a production fluid at high temperatures, such as temperatures ranging from about 80° C. to about 300° C., for separating water from an emulsion in the production fluid.

Abstract: A copolymer useful as a water clarifier for a water phase of a production fluid is selected from those with a first monomer and a second monomer, and in one non-limiting embodiment having the general formula: wherein y is 10 to 50,000; z is 1 to 10,000 and n is 1 to 250. The copolymer may optionally include a third monomer. In an optional embodiment of the process, the fluid has a hydrocarbon phase, and the process further involves simultaneously drying the hydrocarbon phase of the fluid along with clarifying the water phase.
