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: 9581020Abstract: A downhole tool is conveyed within a borehole extending into a subterranean formation. A void is created in a sidewall of the borehole by extending a rotating member from the downhole tool into the sidewall. A portion of the sidewall surrounding the void is mechanically compressed, and the viscosity of hydrocarbons in the subterranean formation proximate the void is reduced by injecting a fluid from the downhole tool into the formation via the void. Fluid comprising the reduced viscosity hydrocarbons and the injected fluid may then be drawn from the subterranean formation into the downhole tool.Type: GrantFiled: January 14, 2013Date of Patent: February 28, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: John E.

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.

Publication number: 20130289961Abstract: Embodiments disclosed herein relate to reservoir characterization techniques and methods for accurately predicting scale tendencies of formation fluids, developed with the newly discovered phenomena that extreme downhole conditions affect the properties of reservoir fluids, including both the brine and dense hydrocarbon gas phases. In one aspect, there is disclosed a method for producing fluids from a geological formation. The method comprises inputting at least one property of a geological formation into an equation of state (EOS) model. The EOS model accounts for bound water, a high temperature effect on the brine and a high temperature effect on the dense gas phase. The EOS model is solved to determine a character of fluids contained in the geological formation, and inputting a production condition or a plurality of production conditions into the EOS model.Type: ApplicationFiled: September 20, 2011Publication date: October 31, 2013Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Indranil Ray, Richard E.
