Publication number: 20230358694Abstract: A method of assessing the response of a reservoir rock to low salinity water includes obtaining a formation core sample of a reservoir rock from a reservoir. In addition, the method includes sequentially washing the formation core sample with a first series of solvents to form a first series of solvent extracts and an extracted formation core sample. Further, the method includes sequentially washing the extracted formation core sample with a second series of solvents to form a second series of solvent extracts and a cleaned formation core sample. The method also includes generating a series of mass spectra of the second series of solvent extracts. The relative abundance of the catecholamine-type structures (CTS) is determined using the series of mass spectra. Still further, the method includes subjecting the formation core sample to analysis by X-ray diffraction to generate a diffraction pattern. The relative abundance of kalonite is determined using the diffraction pattern.Type: ApplicationFiled: December 1, 2021Publication date: November 9, 2023Applicant: BP CORPORATION NORTH AMERICA INC.Inventors: Huang Zeng, Christianne Clare Wicking, Nathalia Tessarolo, John William Couves, Ian Ralph Collins

Patent number: 9410936Abstract: A methodology that performs downhole fluid analysis of fluid properties of a reservoir and characterizes the reservoir based upon such downhole fluid analysis. The methodology acquires at least one fluid sample at a respective measurement station and performs downhole fluid analysis to measure properties of the fluid sample, including concentration of a plurality of high molecular weight components. For each of a plurality of type classes corresponding to different subsets of a predetermined set of high molecular weight components, a model is used to predict the concentration of the components of the given type class for the plurality of measurement stations. The predicted concentrations of the high molecular weight components for the plurality of type classes are then compared with corresponding concentrations measured by downhole fluid analysis for the plurality of measurement stations to identify the best matching type class. The results of the comparison are used for reservoir analysis.Type: GrantFiled: August 10, 2010Date of Patent: August 9, 2016Assignee: Schlumberger Technology CorporationInventors: Youxiang Zuo, Denise E. Freed, Oliver Clinton Mullins, Christopher Harrison, Mary Jane Tsang Mui Ching, Huang Zeng

Patent number: 9395348Abstract: A system and methodology enables improved quantification of an organic material, e.g. oil, in a sample. The technique comprises adding a substance to a two-phase sample containing the organic material and water. The substance is mixed through the sample until the constituents of the sample are solubilized to create an optically clear mixture. An optical technique is employed with respect to the optically clear mixture to quantitatively analyze the organic material in the sample.Type: GrantFiled: October 22, 2012Date of Patent: July 19, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Geza Horvath Szabo, Huang Zeng, Ahmad Billal Sultani

Publication number: 20140262243Abstract: A method for mobilizing viscous hydrocarbons in a reservoir includes (a) injecting an aqueous solution into the reservoir with the reservoir at the reservoir ambient temperature. The aqueous solution includes water and a water-soluble chemical agent that is substantially non-decomposable and substantially non-reactive in the reservoir at the reservoir ambient temperature.

Patent number: 6782335Abstract: A method for estimating the input power to a cable modem includes generating a look-up table containing AGC integrator accumulator values corresponding to selected frequencies and amplitudes. The look-up table is generated by first constructing a calibration matrix by inputting a plurality of calibration signals having known input frequencies and known input power levels into the cable modem's receiver, and recording AGC integrator accumulator values corresponding to several frequencies and power levels over a selected operating range as calibration points. Next, an interpolation and extrapolation process generates the look-up values corresponding to the frequencies and amplitudes in between the calibration points. During modem operation, the modem estimates the input power by checking the AGC integrator accumulator value corresponding to the input frequency and amplitude.Type: GrantFiled: September 26, 2000Date of Patent: August 24, 2004Assignee: General Instrument CorporationInventors: Kevin Lynaugh, Michael Andrew Grossman, Yong Huang Zeng
