Publication number: 20230104036Abstract: The present disclosure provides a workflow for modelling EOR flooding operations performed on a reservoir by separating front tracking from the reservoir simulation process, so that the fronts position and topology evolves in parallel with the coarse grid simulation, through modifications using machine-learning-trained correlations.Type: ApplicationFiled: March 3, 2021Publication date: April 6, 2023Inventors: Barys Andreevich SAMSON, Sophie Nazik GODEFROY, Soham SHETH, Christopher MAROONEY

Patent number: 10534871Abstract: Fluid property modeling that employs a model that characterizes asphaltene concentration gradients is integrated into a reservoir modeling and simulation framework to allow for reservoir compartmentalization (the presence or absence of flow barrier in the reservoir) to be assessed more quickly and easily. Additionally, automated integration of the fluid property modeling into the reservoir modeling and simulation framework allows the compositional gradients produced by the fluid property modeler (particularly asphaltene concentration gradients) to be combined with other data, such as geologic data and other petrophysical data, which allows for more accurate assessment of reservoir compartmentalization.Type: GrantFiled: March 9, 2011Date of Patent: January 14, 2020Assignee: Schlumberger Technology CorporationInventors: Andrew E. Pomerantz, Youxiang Zuo, John Waggoner, Zulfiquar Ail Reza, Sophie Nazik Godefroy, Thomas Pfeiffer, Denise E. Freed, Oliver C. Mullins

Patent number: 8393207Abstract: Methods and apparatus to use multiple sensors to measure downhole fluid properties are described. An example method of measuring a property of a downhole fluid involves obtaining a plurality of measurements for each of a plurality of sensors. Each of the measurements corresponds to a same property of the downhole fluid, and each of the sensors is differently configured to measure the property. Additionally, the example method involves obtaining a plurality of weighting values, each of which corresponds to one of the sensors. The example method also involves applying the weighting values to the respective measurements obtained by each of the corresponding sensors to generate a weight-corrected measurement for each of the sensors. Further still, the example method involves generating a value representative of a measurement of the property of the downhole fluid based on the weight-corrected measurements and outputting the value representative of the measurement of the property.Type: GrantFiled: February 16, 2009Date of Patent: March 12, 2013Assignee: Schlumberger Technology CorporationInventors: Go Fujisawa, Sophie Nazik Godefroy

Patent number: 8166812Abstract: Vibrating wire viscometers are disclosed. An example apparatus to determine the viscosity of a downhole fluid is described, the apparatus including a wire to be immersed in a downhole fluid, to vibrate when an alternating current is applied to the wire within a magnetic field, and to generate an electromotive force when vibrating within the magnetic field, the wire comprising a first resistance. The apparatus further includes a nulling circuit coupled to the wire, wherein the nulling circuit comprises a second resistance that is selectable to be substantially equal to the first resistance, and an analyzer coupled to the wire and the nulling circuit to determine the first resistance, the second resistance, and a viscosity of the downhole fluid based on the first and second resistances, at least one characteristic of the wire, and the electromotive force.Type: GrantFiled: October 14, 2009Date of Patent: May 1, 2012Assignee: Schlumberger Technology CorporationInventors: Emmanuel Desroques, Sophie Nazik Godefroy, Anthony Robert Holmes Goodwin, Christopher Harrison, Kai Hsu, Noriyuki Matsumoto
