Patent number: 11441420Abstract: Well completion is accomplished by obtaining a sample of geological material from the subsurface and generating primary data for the sample of geological material. The primary data include textural data, chemical data and mineralogical data. The primary data are used to derive secondary data for the sample of geological material, and the primary data and the secondary data are used to generate tertiary data for the sample of geological material. The tertiary data are a quantification of physical characteristics of the sample of geological material. The primary data, secondary data and tertiary data are used to determine a location of a stage along a well and an arrangement of perforation clusters in the stage.Type: GrantFiled: September 6, 2017Date of Patent: September 13, 2022Assignee: CGG SERVICES SASInventors: Graham Spence, Chi Vinh Ly, Guy Oliver

Patent number: 11435335Abstract: An exploration method starts from cuttings associated with sampling intervals and well data for a well in a subsurface formation. The cuttings are prepared and analyzed to extract textural and chemical/mineralogical data for plural fragments in each sample that is made of the cuttings in one sampling interval. The method then includes matching lithotypes of rock defined according to the textural and chemical/mineralogical data for each fragment with segments of the well data in the corresponding sampling interval to obtain correspondences between the lithotypes and depth ranges. The correspondences between the lithotypes and the depth ranges may be used as constraints for seismic data inversion.Type: GrantFiled: June 26, 2020Date of Patent: September 6, 2022Assignee: CGG SERVICES SASInventors: Chi Vinh Ly, Ross Taylor

Patent number: 10935481Abstract: A method for estimating breakdown pressure values along a wellbore starts from analyzing cuttings from locations along the wellbore to determine rock properties, including rock texture information associated with the locations. The anisotropic elastic and mechanical properties at the locations are calculated based on the rock properties and using at least one rock physics model. Rock weakness index values corresponding to the locations are then calculated based on the anisotropic elastic and mechanical properties and the rock texture information. The breakdown pressure values at the locations are estimated from the rock weakness index values.Type: GrantFiled: July 17, 2018Date of Patent: March 2, 2021Assignee: CGG SERVICES SASInventors: Fabien Allo, Chi Vinh Ly

Publication number: 20200103541Abstract: A seismic exploration method used lateral well data to validate lateral elastic properties values. The validated lateral elastic properties values are obtained by generating a constrained 3D rock facies model using the lateral and vertical well data and the seismic inversion results, cross-correlating synthetic lateral elastic properties values for locations along the lateral well, based on the lateral and vertical well data with the seismic inversion results to obtain calibrated synthetic lateral elastic properties values, and adjusting the calibrated synthetic lateral elastic properties values according to the constrained 3D rock facies model.Type: ApplicationFiled: April 29, 2019Publication date: April 2, 2020Inventors: Ahmed MOHAMED, Chi Vinh LY

Patent number: 10184906Abstract: Predicting and quantifying free silicon in a geological formation generates free silicon data for a physical sample obtained from within the geological formation. The free silicon data include identification of portions of the physical sample containing free silicon and a quantification of the free silicon contained in the portions of the physical sample containing free silicon. A modified petro-elastic model for the geological formation comprising rock constituents is generated that incorporates free silicon as one of the rock constituents and that quantitatively models how free silicon changes elastic properties within the geological formation. A three-dimensional model of the geological formation is created that indicates volumes of free silicon throughout the geological formation. The three-dimensional model is created using geophysical data obtained from the physical sample, seismic data covering the geological formation and the modified petro-elastic model.Type: GrantFiled: May 4, 2016Date of Patent: January 22, 2019Assignee: CGG SERVICES SASInventors: Guy Oliver, Graham Spence, Chi Vinh Ly, Fabien Allo
