Abstract: The present disclosure is generally directed to an apparatus for pumping suspended polymer liquids that reduces the formation of polymeric deposits at the seal contact surfaces and filters out deposits that do form. This allows for an oil drag reducing agent (DRA) to be delivered continuously from topside through an umbilical to subsea produced fluids flowlines to increase oil production and/or flow of gas/oil by reducing friction loss due to turbulent flow in the flowlines.

Abstract: Methods for determining corrected positions of a global navigation satellite system (GNSS) rover using a GNSS base station and one or more GNSS reference stations include determining a statistical representation of position measurements from the GNSS reference stations and an instantaneous position measurement from the GNSS reference stations.

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.

Abstract: A system for vertical accuracy improvement includes a reference station, a rover, and a base station in communication with the reference station and the rover. The base station includes a GNSS antenna, an actuator coupled to the GNSS antenna, a wireless transceiver, a processor, and non-transitory computer readable media comprising instructions executable by the processor. The instructions may be executed to cause the base station to receive a first vertical error from the reference station. The base station may further be configured to determine a second vertical position at which the first vertical error is reduced, and adjust the GNSS antenna to be in the second vertical position. The base station may further be configured to generate correction data based at least in part on the phase of the carrier wave signal at the second vertical position, and transmit the correction data to the rover.

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.
