The values correspond to a set of property parameters. The embodiment comprises performing bi-variate modelling on the set of property parameters to generate bi-variate relationships for the set of property parameters and selecting the bi-variate relationships that satisfy correlation criteria; performing multi-variate modelling on the property parameters corresponding to the unselected bi-variate relationships to generate multi-variate relationships for the unselected bi-variate relationships and selecting the multi-variate relationships that satisfy the correlation criteria; and combining the bi-variate models corresponding to the selected bi-variate relationships and the multi-variate models corresponding to the selected multi-variate relationships to generate a combined model comprising the corresponding parameters.Type: ApplicationFiled: December 6, 2021Publication date: June 9, 2022Applicant: CHEVRON U.S.A.

Patent number: 10634746Abstract: To measure the phase behavior of a fluid in a porous medium such as a tight gas shale, one illustrative method involves: (a) loading the fluid into a sample cell containing the porous medium; (b) setting a pressure and a temperature for the fluid in the sample cell; (c) applying an RF pulse sequence to the fluid in the sample cell to acquire an NMR signal; (d) deriving from the NMR signal an NMR parameter distribution that depends on the pressure and the temperature; (e) determining whether a fluid phase is present based on the NMR parameter distribution; (f) repeating operations (c) through (f) to determine the presence or absence of the fluid phase at multiple points along a pressure-temperature path that crosses a phase boundary; and (g) providing an estimated location of the phase boundary based on the presence or absence of the fluid phase at said points.Type: GrantFiled: March 29, 2017Date of Patent: April 28, 2020Assignee: CHEVRON U.S.A.

Patent number: 9851315Abstract: A method for determining the concentration of asphaltenes in a solution is described. A model is first established for estimating the concentration of asphaltenes in a solution based on multiple samples of solutions of asphaltenes in the solvent in which the concentrations are known. The multiple samples have varying concentrations of asphaltenes. The diffusivity and relaxation time are measured for each sample using two-dimensional NMR. The ratio of diffusivity to relaxation time for each sample is then calculated. A linear equation is determined to fit the relationship between the ratio of diffusivity to relaxation time and the asphaltene concentration by weight for the multiple samples, thus creating the model. For a given solution sample for which the concentration of asphaltenes is desired to be determined, diffusivity and relaxation time are determined using two-dimensional NMR, and the ratio of diffusivity to relaxation time is calculated.Type: GrantFiled: December 11, 2014Date of Patent: December 26, 2017Assignee: Chevron U.S.A.
