Patent number: 11333650Abstract: This disclosure relates methods and systems for determining asphaltene inhibitor properties. For example, one embodiment provides a method for determining a content of disaggregated asphaltene in an inhibited crude oil. The method includes measuring the dielectric constant of a sample of the crude oil, the sample having a first concentration of an asphaltene inhibitor; providing a first dielectric correction factor for the first concentration of the asphaltene inhibitor; calculating, e.g., by a computing device, a first corrected dielectric constant of the sample having the first concentration, using the first dielectric correction factor; and determining the content of disaggregated asphaltene in the first crude oil sample, based on the first corrected dielectric constant. Methods for inhibiting asphaltene aggregation in crude oil are also provided.Type: GrantFiled: September 17, 2019Date of Patent: May 17, 2022Assignee: Clariant International Ltd.Inventors: Paul R Hart, Abhishek Punase, Rama Rao Alapati

Patent number: 10027284Abstract: An embodiment of an amplifier system includes a modifiable signal adjustment device with an RF signal adjustment circuit coupled between first and second nodes. The RF signal adjustment circuit includes an adjustable phase shifter and an adjustable attenuator coupled in series with each other. The device also includes a memory and a controller circuit. The controller circuit retrieves a phase shift value and an attenuation value from the memory. The controller circuit then controls the adjustable phase shifter to apply a phase shift corresponding to the phase shift value to an input RF signal received at the first node, and controls the adjustable attenuator to apply an attenuation corresponding to the attenuation value to the input RF signal. Applying the phase shift and the attenuation results in an output RF signal at the second node.Type: GrantFiled: December 29, 2016Date of Patent: July 17, 2018Assignee: NXP USA, INC.Inventors: Joseph Staudinger, Abdulrhman M.

Patent number: 9574429Abstract: Air and ammonia gas are introduced into a subterranean formation during the in-situ combustion to increase the mobility of hydrocarbons in a subterranean formation and facilitate recovery of the hydrocarbons from the subterranean formation. The air supports in-situ combustion of a portion of the hydrocarbon within the subterranean formation to form water and establish a combustion front. The ammonia gas contacts the hydrocarbons ahead of the combustion front and reacts in-situ with naphthenic acid in the hydrocarbon to form a surfactant. The hydrocarbons, water and surfactant then form an oil-in-water emulsion that drains more freely through the formation. A production well, in fluid communication with the hydrocarbons ahead of the combustion front, may be used to remove the oil-in-water emulsion from the subterranean formation.Type: GrantFiled: September 21, 2012Date of Patent: February 21, 2017Assignee: Nalco CompanyInventor: Paul R.
