Abstract: A method includes driving a fluid pumping unit having a plurality of pumping cylinders via a plurality of hydraulic cylinders respectively of a hydraulic power unit. The method further includes controlling activation of the hydraulic power unit such that each stroke of the corresponding piston assembly between the top dead center and the bottom dead center follows a corresponding trapezoidal velocity profile with respect to a time duration. Controlling activation includes controlling flow of a hydraulic fluid in the hydraulic power unit so as to control the corresponding trapezoidal velocity profile with respect to the time duration of the corresponding piston assembly to obtain a predefined flow rate of the fluid medium from the pumping unit.

Abstract: A method for recovering oil from an oil-bearing formation is presented. The method includes providing a reverse osmosis (RO) unit comprising at least one membrane; feeding a first feed stream having a first salinity content to a first side of the membrane; and feeding a second feed stream having a second salinity content to a second side of the membrane. The method further includes discharging a retentate stream from the first side of the membrane, and discharging a product stream having a controlled salinity content from the second side of the membrane. The method furthermore includes injecting at least a portion of the product stream into the oil-bearing formation, and recovering at least a portion of the oil from the oil-bearing formation. A system for recovering oil from an oil-bearing formation is also presented.

Abstract: Methods for manufacturing composite components having complex geometries are provided. In one exemplary aspect, a method includes laying up each of a plurality of laminates to an initial shape with a substantially planar geometry or a gently curved geometry. Then, a laid up laminate is formed to a final shape for each predefined section defined by the composite component to be manufactured. Thereafter, the laminates formed to their respective final shapes are stacked to build up the complex geometry of the composite component. Next, the composite component can be cured and finish machined as necessary to form the completed composite component.

Abstract: According to present embodiments or aspects thereof, a composite booster spool with separable composite blades is provided. The blades are inserted radially from within the inner circumference of the spool and extend outwardly through the spool. The system provides a reduced weight assembly as compared to prior art metallic or composite/metallic combination systems. Additionally, the blades are separable which results in a more field-serviceable assembly over a fully integral system wherein the blades and spool are integrally formed from composites or combination of metal and composites.
