Patent number: 11066905Abstract: A method for modelling saturation in a reservoir, comprising: obtaining capillary pressure data representing capillary pressure in the reservoir; obtaining permeability data representing permeability in the reservoir; determining a number of pore throats represented by the capillary pressure data; creating hyperbolic tangents based on the capillary pressure data equal in number to the number of pore throats; combining hyperbolic tangents to create a curve to fit the capillary pressure data and to define hyperbolic tangent parameters; combining at least one of the hyperbolic tangent parameters with the permeability data to define a saturation height function; modelling a saturation in the reservoir using the saturation height function; and displaying the saturation model based on the saturation height function.Type: GrantFiled: June 24, 2016Date of Patent: July 20, 2021Assignee: Schlumberger Technology CorporationInventors: Sylvain Wlodarczyk, Keith Pinto, Olivier Marche, Akshat Gupta

Patent number: 10787902Abstract: A system and method for correcting capillary pressure curves includes creating a capillary pressure curve using multiple linked hyperbolic tangents, determining a closure correction pressure cutoff of the capillary pressure curve, and correcting the capillary pressure curve. The correction may include normalizing the capillary pressure curve and extrapolating the capillary pressure curve.Type: GrantFiled: May 31, 2016Date of Patent: September 29, 2020Assignee: Schlumberger Technology CorporationInventors: Sylvain Wlodarczyk, Keith Pinto, Olivier Marché, Akshat Gupta

Patent number: 10655461Abstract: A method, apparatus, and program product for determining a formation pressure for a reservoir. Measurement data for a pretest of a formation of the reservoir is received. The measurement data is analyzed to determine a last-read event and a corresponding last-read pressure. Derivative data for flow regime identification is determined based at least in part on the measurement data. The derivative data is analyzed to determine a pressure derivative response, and a formation pressure is determined based at least in part on the last-read event, the last-read pressure, and the pressure derivative response.Type: GrantFiled: March 3, 2016Date of Patent: May 19, 2020Assignee: Schlumberger Technology CorporationInventors: Keith Pinto, Olivier Marché

Patent number: 10444402Abstract: Systems, methods, and media for processing formation pressure test data are provided. The method includes determining using a processor, a plurality of regressions for measurements of the formation pressure test data, and determining that two or more of the plurality of regressions represent a fluid code. The method also includes combining the two or more of the plurality of regressions representing the fluid code to generate a first fluid-type regression, and combining two or more other ones of the plurality of regressions representing a second fluid code to generate a second fluid-type regression. The method further includes determining that the first fluid-type regression and the second fluid-type regression are in a first hydraulic zone, and calculating a location of a boundary between the first fluid-type regression and the second fluid-type regression by extrapolating the first and second fluid-type regressions to a point of intersection therebetween.Type: GrantFiled: May 24, 2013Date of Patent: October 15, 2019Assignee: Schlumberger Technology CorporationInventors: Francois Dubost, Yannick Guyomar, Olivier Marché, Cosan Ayan, Florent d'Halluin, Sylvain Wlodarczyk

Patent number: 10371619Abstract: A method can include receiving porosimetry data for a range of pressures that spans a transition zone defined at least in part by a high-pressure end of a first pressure zone and a low-pressure end of a second pressure zone; detecting at least one artifact in the transition zone; computing accuracy information for the high-pressure end of the first pressure zone and the low-pressure end of the second pressure zone; computing a pressure-volume adjustment based at least in part on the accuracy information; and outputting a pressure-volume relationship in the transition zone based at least in part on the pressure-volume adjustment.Type: GrantFiled: January 26, 2016Date of Patent: August 6, 2019Assignee: Schlumberger Technology CorporationInventors: Olivier Marche, Andrey Vladimirovich Kazak, Keith Pinto
