Systems and Methods for Identifying Two or More Charges into Reservoir Using Downhole Fluid Analysis
Publication number: 20240151139Abstract: Systems and methods for identifying a likelihood that a reservoir of a geological formation received a secondary charge of hydrocarbons of relatively very different thermal maturity of composition are provided. One method includes positioning a downhole acquisition tool in a wellbore in a geological formation and testing one or more fluid properties of the formation fluid. Data processing circuitry may identify whether a relationship of the one or more fluid properties exceeds a first threshold that indicates likely asphaltene instability. When this is the case, data processing circuitry may be used to model the geological formation using a realization scenario in which multiple charges of hydrocarbons of substantially different thermal maturity or substantially different composition, or both, filled a reservoir of the geological formation over geologic time.Type: ApplicationFiled: January 8, 2024Publication date: May 9, 2024Inventors: Hadrien Dumont, Vinay K.

Patent number: 11768191Abstract: Embodiments of the disclosure can include systems, methods, and devices for determining saturation pressure of an uncontaminated fluid. A technique facilitates fluid analysis in situ at a downhole location. Downhole saturation pressure measurements and downhole OBM filtrate contamination of a contaminated fluid may be obtained and a relationship may be determined between the saturation pressure measurements and OBM filtrate contamination. The relationship may be extrapolated to zero OBM filtrate contamination to determine the saturation pressure of the uncontaminated fluid. According to an embodiment, a sample of oil is obtained at the downhole location from oil in a reservoir. A downhole sampling system is used to determine whether a sample has contamination and other selected characteristics of the sample. The data obtained may be processed to provide a formation volume factor of the oil.Type: GrantFiled: May 13, 2021Date of Patent: September 26, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Younes Jalali, Ryota Tonoue, Hua Chen, Christopher Harrison, Kamal Kader, Youxiang Zuo, Adriaan Gisolf, Cosan Ayan, Michael Mallari Toribio, Chetankumar Natwarlal Desai, Oliver Clinton Mullins, Matthew T.

Patent number: 11725511Abstract: Methods for obtaining in-situ, multi-temperature measurements of fluid properties, such as saturation pressure and asphaltene onset pressure include obtaining a sample of formation fluid using a downhole acquisition tool positioned in a wellbore in a geological formation. The downhole acquisition tool may be stationed at a first depth in the wellbore that has an ambient first temperature. While stationed at the first depth, the downhole acquisition tool may test a first fluid property of the sample to obtain a first measurement point at approximately the first temperature. The downhole acquisition tool may be moved to a subsequent station at a new depth with an ambient second temperature, and another measurement point obtained at approximately the second temperature. From the measurement points, a temperature-dependent relationship of the first fluid property of the first formation fluid may be determined.Type: GrantFiled: August 30, 2021Date of Patent: August 15, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Hadrien Dumont, Christopher Harrison, Youxiang Zuo, Christopher Albert Babin, Li Chen, Vinay K.

Patent number: 11280191Abstract: A methodology that performs fluid sampling within a wellbore traversing a reservoir and fluid analysis on the fluid sample(s) to determine properties (including asphaltene concentration) of the fluid sample(s). At least one model is used to predict asphaltene concentration as a function of location in the reservoir. The predicted asphaltene concentrations are compared with corresponding concentrations measured by the fluid analysis to identify if the asphaltene of the fluid sample(s) corresponds to a particular asphaltene type (e.g., asphaltene clusters common in heavy oil). If so, a viscosity model is used to derive viscosity of the reservoir fluids as a function of location in the reservoir. The viscosity model allows for gradients in the viscosity of the reservoir fluids as a function of depth. The results of the viscosity model (and/or parts thereof) can be used in reservoir understanding workflows and in reservoir simulation.Type: GrantFiled: January 17, 2013Date of Patent: March 22, 2022Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Youxiang Zuo, Oliver C.

Patent number: 10975693Abstract: Disclosed are methods and apparatus pertaining to processing in-situ, real-time data associated with fluid obtained by a downhole sampling tool. The processing includes generating a population of values for ?, where each value of ? is an estimated value of a fluid property for native formation fluid within the obtained fluid. The obtained data is iteratively fit to a predetermined model in linear space. The model relates the fluid property to pumpout volume or time. Each iterative fitting utilizes a different one of the values for ?. A value ?* is identified as the one of the values ? that minimizes model fit error in linear space based on the iterative fitting. Selected values ? that are near ?* are then assessed to determine which one has a minimum integral error of nonlinearity in logarithmic space.Type: GrantFiled: November 7, 2019Date of Patent: April 13, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Ryan Sangjun Lee, Adriaan Gisolf, Youxiang Zuo
