Publication number: 20210236986Abstract: A method for treating a natural gas containing carbon dioxide using membrane modules which are assigned to a first treatment stage or a second treatment stage and are fluidically connected to a retentate mode or a permeate mode. When evolution in the operating conditions results in one of the processing levels requiring less membrane surface for gas processing and the other processing level requiring more membrane surface for gas processing, then the method allows for reassignment of needed membrane modules assigned from one processing level requiring less membrane surface to another processing level requiring more membrane surface.Type: ApplicationFiled: January 17, 2018Publication date: August 5, 2021Applicant: T0TAL SAInventors: Phuc-Tien THIERRY, Denis CHRETIEN, Claire WEISS, SALIM AZZI, Aneke IGWUME

Publication number: 20200325765Abstract: The present invention relates to a method for determining hydrocarbon production for a reservoir. The method comprises determining a projector matrix based on a Jacobian matrix function of the gridded model, then splitting the Jacobian matrix into subsets of consecutive lines. For each subset of consecutive lines, creating a respective square matrix based on said subset. A determining eigenvectors and respective eigenvalues associated with the respective square matrix and then determining relevant eigenvectors having respective eigenvalues below a predetermined threshold. The projector is determined as a concatenation of the extended eigenvectors ordered according to multiple criteria: the respective order value of the subset; and the respective eigenvalue of the relevant eigenvector.Type: ApplicationFiled: November 24, 2017Publication date: October 15, 2020Applicant: T0TAL SAInventors: Pascal HENON, Romain DE LOUBENS

Publication number: 20190219734Abstract: A method for providing a calibrated rock-physics model of a subsoil. First, a geological model of the subsoil comprising a grid made of cells, associated with a rock-physics parameter is obtained. A group of cells forming a calibration body is selected in the grid. The calibration body corresponds to a region of the subsoil having substantially homogenous rock-physics parameter values. Finally, an adjustable constant parameter in a physical equation expressing a relationship between the petro-physical parameter and a petro-elastic parameter in the calibration body is calibrated so as to reduce a mismatch between the petro-elastic parameter estimated using the physical equation and a petro-elastic parameter value determined from inverted seismic data, the calibrated physical equation providing a calibrated rock-physics model of the subsoil in the calibration body.Type: ApplicationFiled: May 15, 2017Publication date: July 18, 2019Applicant: T0TAL SAInventors: Philippe SOLANS, Pierre THORE, Christian HUBANS

Publication number: 20190107526Abstract: A method for determining a plasticity parameter of a hydrating cement paste by mixing the components to obtain a cement slurry, pouring the cement slurry in a sealed oedometric cell, and performing an oedometric measurement operation within a predefined early-age time interval by applying a predefined axial stress path to the cement slurry over a predefined measurement duration and measuring an axial strain. A plasticity parameter of the hydrating cement paste is determined by a calibration processing operation comprising providing an initial value of a plasticity parameter of an elastoplastic model of hydrating cement paste, determining simulated axial strain values by solving the elastoplastic model of hydrating cement and comparing the simulated axial strain values with the axial strain measurements of the cement slurry.Type: ApplicationFiled: April 15, 2016Publication date: April 11, 2019Applicant: T0TAL SAInventors: Christophe URBANCZYK, André GARNIER, Julien SULEM, Siavash GHABEZLOO, Nicolaine AGOFACK
