  • Patent number: 10534871
    Abstract: Fluid property modeling that employs a model that characterizes asphaltene concentration gradients is integrated into a reservoir modeling and simulation framework to allow for reservoir compartmentalization (the presence or absence of flow barrier in the reservoir) to be assessed more quickly and easily. Additionally, automated integration of the fluid property modeling into the reservoir modeling and simulation framework allows the compositional gradients produced by the fluid property modeler (particularly asphaltene concentration gradients) to be combined with other data, such as geologic data and other petrophysical data, which allows for more accurate assessment of reservoir compartmentalization.

  • Patent number: 10385259
    Abstract: 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.

  • Patent number: 9759830
    Abstract: A formation fluid sample is analyzed using NMR spectroscopy to obtain a NMR spectrum. The NMR spectrum is then analyzed to find evidence of the amount of olefins present in the sample. The amount of olefins present in the sample can then be correlated to the level of contamination of the sample. In one embodiment, a 1H chemical shift of between substantially 4.5 and 6 ppm is used to identify olefins present in the sample. In another embodiment, a 1H chemical shift of substantially 1.9 to 2.1 ppm is used to identify olefins present in the sample. The NMR spectral equipment can be located uphole or downhole.

  • Patent number: 9618446
    Abstract: A wellbore tool for determining a speed of sound of a fluid sample, such as a hydrocarbon sample or a wellbore fluid, is described herein. The wellbore tool includes a photoacoustic system for analyzing the fluid sample. The photoacoustic system includes a laser system that generates a laser pulse, an interface disposed between the fluid sample and the laser system, and an acoustic detector that receives an acoustic pulse that is generated in response to absorption of the laser pulse. The acoustic pulse is generated when the laser pulse is absorbed by the fluid sample or the interface. This acoustic pulse then moves through the fluid sample and is detected by the acoustic detector. The acoustic pulse is then used to determine a speed of sound of the fluid sample.

  • Patent number: 9581020
    Abstract: A downhole tool is conveyed within a borehole extending into a subterranean formation. A void is created in a sidewall of the borehole by extending a rotating member from the downhole tool into the sidewall. A portion of the sidewall surrounding the void is mechanically compressed, and the viscosity of hydrocarbons in the subterranean formation proximate the void is reduced by injecting a fluid from the downhole tool into the formation via the void. Fluid comprising the reduced viscosity hydrocarbons and the injected fluid may then be drawn from the subterranean formation into the downhole tool.

  • Patent number: 9416656
    Abstract: A method is disclosed for assessing connectivity between sections in a hydrocarbon reservoir. Samples of hydrocarbons are collected over different depths in at least one wellbore. Fluorescence intensity determines the actual heavy end concentrations of hydrocarbons for the corresponding different depths. Estimated heavy end concentrations of hydrocarbons for corresponding different depths are determined and the actual heavy end concentrations of hydrocarbons are compared with the estimated heavy end concentrations to assess connectivity between sections of the hydrocarbon reservoir.

  • Publication number: 20160082484
    Abstract: A method and apparatus for cleaning a rock core sample loads the sample into a cell where it is supported within an interior chamber of the cell. For at least one interval of time, the sample is soaked with a liquid phase solvent pressurized at elevated pressure and temperature without any flow of the liquid phase solvent into, through, and out of the chamber. The liquid phase solvent is then allowed to drain from the cell. The cell can include a fluid inlet and outlet that are both in fluid communication with the chamber. A controller can be used to control at least one parameter related to the soaking. The at least one parameter can be selected from the group consisting of i) the duration of the time interval, ii) pressure of the liquid phase solvent during the time interval, and iii) temperature of the cell during the time interval.
