Patent number: 10802099Abstract: A methods are provided for investigating a sample containing hydrocarbons by subjecting the sample to a nuclear magnetic resonance (NMR) sequence using NMR equipment, using the NMR equipment to detect signals from the sample in response to the NMR sequence, analyzing the signals to extract a distribution of relaxation times (or diffusions), and computing a value for a parameter of the sample as a function of at least one of the relaxation times (or diffusions), wherein the computing utilizes a correction factor that modifies the value for the parameter as a function of relaxation time for at least short relaxation times (or as a function of diffusion for at least large diffusion coefficients).Type: GrantFiled: April 3, 2018Date of Patent: October 13, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Lalitha Venkataramanan, Fred K.

Patent number: 10613250Abstract: Anisotropic elastic properties and subsequently in situ stress properties for a rock formation surrounding a wellbore are computed from rock physics and geomechanical models. Mineralogy data measured from DRIFTS on cuttings from the wellbore and rock physics and geomechanical models that have been log-calibrated in another wellbore are used in the computation. The method includes: (1) Defining and calibrating rock physics and geomechanical models using data from the first wellbore; (2) using DRIFTS analysis to measure mineralogy data on rock cuttings obtained through drilling operation in the second wellbore; and (3) using previously calibrated models to estimate in situ stress properties, including a stress index and the minimum principal stress magnitude.Type: GrantFiled: July 23, 2015Date of Patent: April 7, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Romain Prioul, Safdar Abbas, Ridvan Akkurt

Patent number: 10451763Abstract: Methods and systems are provided for investigating a rock sample, in which wideband electromagnetic response data are obtained and processed by inversion in order to determine values for a plurality of parameters of the rock sample. The wideband electromagnetic response data is derived from electromagnetic measurements of the rock sample at frequencies that fall within a wideband of frequencies, wherein the wideband of frequencies includes a low frequency sub-band that is sensitive to conductivity of the rock sample and a high frequency sub-band that is sensitive to the permittivity of the rock sample. In one embodiment, the inversion can employ a wideband model that accounts for two different polarization mechanisms. The wideband model can be used to describe predicted electromagnetic response of the rock sample at frequencies that fall within the wideband of frequencies.Type: GrantFiled: October 27, 2016Date of Patent: October 22, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Nikita Valentinovich Seleznev, Chang-Yu Hou, Denise Freed, Ridvan Akkurt

Patent number: 10385259Abstract: Treatment methods and treatment fluids for increasing permeability of organic shale formations are described herein. The treatment method includes treating an organic shale formation with a treatment fluid. The treatment fluid includes a solvent that dissolves bitumen in the shale formation. After treating the shale formation with the treatment fluid, oil is recovered from the shale formation. By removing bitumen from pores and pore throats within the formation, the solvent increases permeability of the formation and allows mobile oil to flow more easily through the formation.Type: GrantFiled: August 7, 2014Date of Patent: August 20, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: George Waters, Richard Lewis, Erik Rylander, Andrew E.

Patent number: 10151674Abstract: Oil-based mud cuttings are cleaned of drilling fluid and mud additives. After sorting and rinsing the cuttings with diesel, the cuttings are put in a syringe, which is repeatedly filled and emptied of diesel. The cuttings are then washed in the syringe with pentane. The cuttings are then crushed and exposed to a solvent a second time. Instead of placing the cuttings in the syringe, alternatively, the cuttings remain on a sieve and the syringe is used to spray the cuttings with diesel, followed by pentane.Type: GrantFiled: January 19, 2017Date of Patent: December 11, 2018Inventors: Mary Ellen Loan, Michael Herron, Ridvan Akkurt, Andrew Emil Pomerantz
