摘要： A methodology that performs fluid sampling within a wellbore traversing a reservoir and fluid analysis on the fluid sample(s) to determine properties (including asphaltene concentration) of the fluid sample(s). At least one model is used to predict asphaltene concentration as a function of location in the reservoir. The predicted asphaltene concentrations are compared with corresponding concentrations measured by the fluid analysis to identify if the asphaltene of the fluid sample(s) corresponds to a particular asphaltene type (e.g., asphaltene clusters common in heavy oil). If so, a viscosity model is used to derive viscosity of the reservoir fluids as a function of location in the reservoir. The viscosity model allows for gradients in the viscosity of the reservoir fluids as a function of depth. The results of the viscosity model (and/or parts thereof) can be used in reservoir understanding workflows and in reservoir simulation.

摘要： Various implementations directed to determining a phase behavior of a reservoir fluid are provided. In one implementation, a method may include receiving a plurality of predetermined pore size data, a plurality of predetermined bulk fluid data, and a plurality of predetermined kerogen data that are based on historical data for a plurality of hydrocarbon reservoirs. The method may also include creating a library of a plurality of simulated phase behavior data for the predetermined pore size data, the predetermined bulk fluid data, and the predetermined kerogen data. The method may further include determining a phase behavior of a reservoir fluid disposed in an actual hydrocarbon reservoir using the library.

摘要： A method for downhole fluid analysis by optical spectroscopy with photoacoustic detection includes positioning a photoacoustic system within a wellbore, applying a laser pulse to the fluid sample using the pulsed laser system, detecting, by the acoustic sensor, a time-resolved acoustic pulse generated by absorption of the laser pulse by the fluid sample, and determining a property of the fluid sample using the detected time resolved acoustic pulse. The photoacoustic system includes a pulsed laser system and an acoustic sensor.

摘要： 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.

摘要： 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.

摘要： A downhole tool is conveyed within a borehole extending into a subterranean formation. Fluid is drawn from the subterranean formation into the downhole tool, wherein the fluid comprises heavy oil. Fluorescence intensity of the drawn fluid is measured via a sensor of the downhole tool, and asphaltene content of the drawn fluid is estimated based on the measured fluorescence intensity.

摘要： 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.
