Abstract: A polymer composition has been developed that provides low viscosity oil-in-water polymer emulsions that release the polymer in the emulsion at a faster rate and without an additional surfactant when the emulsion is added to a hydrocarbon stream. Use of a temperature-sensitive emulsifying surfactant facilitates inversion of the oil-in-water polymer emulsion when applied to a hydrocarbon composition at a temperature sufficiently high to destabilize the emulsion. These compositions are particularly useful as drag reducers for delivery to a subsea flowline via an umbilical line.

Abstract: The present invention is a battery-powered, remote-controllable rollator with embedded computer systems and computer vision system. The present invention recognizes the user's face by using artificial intelligence technology, namely, the deep convolutional neural networks, and uses that information to localize the rollator's position in relation to the user. An artificial intelligence algorithm computes the motion path and drives the present invention to the user. The present invention can automatically stop once approached to a preset stopping distance from the user. Once stationary, the present invention can then be used by the user.

Abstract: Emulsions of mobility control polymers can be used to increase recovery of crude oil from a subterranean hydrocarbon-containing formation. A flooding fluid comprising the polymer emulsions are injected into a well that is in contact with the subterranean hydrocarbon-containing formation. The polymers can be temporarily cross-linked and have protected shear degradation and improved injectivity into the well; the shear resistance can be measured in terms of viscosity loss due to shear, and the improved injectivity can be measured in terms of the flooding fluid's filter ratio, flow rate, and viscosity.

The disclosed cloud point depressants comprise copolymers of an unsaturated anhydride polymerized with alkyl ?-olefins and then contacted with a phenyl alkyl alcohol or alkyl phenol alkoxylate, fatty alcohol and primary or secondary fatty amine to provide a cloud depressant reaction product. When the disclosed reaction products are added to middle distillate fuels or blends of middle distillate fuels with biodiesel, the cloud point depressants inhibit the precipitation of waxes and/or biowaxes in the fuels and the fuels exhibit reduced precipitation, gelling, and/or crystallization when subjected to low or cold temperatures.

Abstract: A polymer composition has been developed that provides low viscosity oil-in-water polymer emulsions that are stable to shear conditions and are storage stable at low temperature conditions (e.g., ?6.7° C. or less) or higher temperature conditions (e.g., up to 60° C.). Use of particular additives provides stability to the emulsion and imparts advantageous properties when the polymer composition is contacted with a hydrocarbon fluid. These compositions are particularly useful as drag reducers for delivery to a subsea flowline via an umbilical line.
