    摘要： A method includes placing a downhole acquisition tool in a wellbore in a geological formation within a hydrocarbon reservoir that contains a reservoir fluid. The method also includes performing downhole fluid analysis using the downhole acquisition tool in the wellbore to determine a measurement associated with the reservoir fluid and using a processor to: estimate a fluid component property by using an equation of state based the measurement and simulate a diffusion process using a diffusive model that takes into account the estimated fluid property. The diffusive model accounts for gravitational diffusion of components in the reservoir fluid. The method also includes using the processor to estimate reservoir fluid geodynamic processes based on the fluid property; compare the estimated reservoir fluid geodynamic processes with the measurement associated with the reservoir fluid; and output reservoir fluid geodynamic processes corresponding to the measurement associated with the reservoir fluid.

    摘要： Various implementations directed to the integration of seismic data with downhole fluid analysis to predict the location of heavy hydrocarbon are provided. In one implementation, a method may include receiving seismic data for a hydrocarbon reservoir of interest. The method may also include identifying geological features associated with a secondary gas charge from the seismic data. The method may further include determining the proximity of the geological features to the hydrocarbon reservoir of interest. The method may additionally include receiving preliminary downhole fluid analysis (DFA) data from formations at or near the hydrocarbon reservoir of interest. The method may further include analyzing the preliminary DFA data to determine the equilibrium state of the hydrocarbon reservoir and to confirm the secondary gas charge in the hydrocarbon reservoir. The method may also include determining whether to perform one or more additional DFA's.

    摘要： A method includes placing a downhole acquisition tool in a wellbore in a geological formation within a hydrocarbon reservoir. The wellbore or the geological formation, or both, contain a reservoir fluid. The method also includes performing downhole fluid analysis using the downhole acquisition tool in the wellbore to determine at least one measurement associated with the reservoir fluid and using a processor to: estimate at least one fluid component property by using an equation of state based at least in part on at least one measurement associated with the reservoir fluid and simulate a diffusion process using a diffusive model that takes into account the at least one estimated fluid property. The diffusive model accounts for gravitational diffusion of at least one or more components in the reservoir fluid. The method also includes using the processor to estimate one or more reservoir fluid geodynamic processes based at least in part on the at least one fluid property; compare the estimated one or more reservoir fluid geodynamic processes with the at least one measurement associated with the reservoir fluid; and output one or more reservoir fluid geodynamic processes corresponding to the at least one measurement associated with the reservoir fluid.
