Abstract: Generating heat within a combination solvent/acid system removes undesirable deposits from petroleum reservoir formations (especially the near well-bore region), oilfield equipment, and petroleum processing equipment. An exothermic reaction occurs between the solvent and the acid and the heat evolved helps remove organic solid deposits. The acids may include organic acid compounds, such as sulfonic acids, sulfuric acid and nitric acid. The solvents may include terpene- and terpene-derivative-containing solvents, including, but not necessarily limited to, limonene, pinene, dipentene, myrcene, turpentines and compounds having at least one double bond, such as methyl furan, dienes, styrene, vinyl acetate and the like. The exothermic reaction produces a great amount of heat, and together with using certain acids and solvents already known as effective to remove paraffin and asphaltene deposition, removing such deposits is improved.

Inventor: GU MICHAEL
IPC: E21B43/24
Filed: 2013-01-10
Granted: 2018-11-06
Abstract: Techniques for generating steam and treating de-oiled produced water can include various steps that involve recycling certain streams and using a Once Through Steam Generator (OTSG). A first de-oiled produced water stream can be softened to produce softened water. A second de-oiled produced water stream can be subjected to evaporation to produce a distillate. Portions of the distillate and the softened water can be fed as a boiler feed water stream to an OTSG to produce wet steam, which is separated into dry steam and a blowdown stream with a concentrated level of impurities.  At least a recycle portion of the blowdown stream can be sent back as part of the boiler feed water stream. In addition, multiple steam generation trains, which each use an OTSG, can be integrated to reuse certain aqueous streams.

Abstract: A computer-implemented method of annotating an electronic document may include receiving annotation information corresponding to a first electronic document file and creating annotation metadata that is associated with the annotation information. The method may further include storing the annotation information and associated annotation metadata in an annotation file that is separate from the first electronic document file, and anchoring the annotation information to a target electronic document file at an anchor location corresponding to the annotation metadata. The annotation metadata may be generated by assigning a target offset value to individual neighboring tokens defining an annotation neighborhood, wherein the target offset values correspond to positions of the neighboring tokens with respect to an annotation location within the first electronic document file. The annotation metadata may also comprise topographic patterns that are compared between source and target documents to determine the anchor location.

Abstract: Audio processing devices and methods. An ambient microphone picks up ambient sound and a voice microphone picks up a speaker's voice. The voice microphone is located farther from the speaker's mouth when a device is held to one side of the speaker's face than when held to the other side. A signal indicates whether an expected position of the handheld body is a position on a left side or right side of a speaker's face. Ambient sound in the voice signal is reduced by applying a first algorithm configuration selected to process voice signals with lower signal-to-noise ratio when the expected position in on one side of the speaker's face, and by applying a second sound cancellation algorithm configuration selected to process higher signal-to-noise ratios when the expected position is on the other side of the speaker's face.

Abstract: Accurate measurements of electrical power at various points of a power grid is becoming more important and, at the same time, is getting more difficult as the old power distribution model of a few, large power generating stations and a multitude of relatively linear loads is replaced by a newer model containing a multitude of smaller, and to some degree unpredictable power sources, as well as a multitude of not always linear and often smart (essentially also unpredictable) loads. Embodiments of the invention provide for high accuracy voltage, current and power measurements of quasi-stationary and stationary waveforms in single and multiple phase power systems. Precision AC voltage, current, phase, power and energy measurements in power networks may be measured with current ranges from 1mA to 20kA and voltage ranges from 1V to 1000kV and in a frequency range from a few hertz to one hundred kilohertz.
