    摘要: This invention relates to methods for calibrating a formation permeability model with respect to data obtained from fluid flow measurements. A method according to the invention includes determining a correlation coefficient for a porosity - irreducible water saturation relationship; determining a leading coefficient for a formation permeability model; and determining at least one exponent parameter for the formation permeability model by minimizing a basis function that represents a difference between a formation permeability estimate derived from the formation permeability model and a formation permeability estimate derived from the fluid flow measurements.

    摘要: A method of and process for fractured well diagnostics for production data analysis for providing production optimization of reservoir completions via available production analysis and production logging data provides a quantitative analysis procedure for reservoir and fracture properties using commingled reservoir production data, production logs and radial flow and fractured interval analyses. Production logging data is used to correctly allocate production to each completed interval and defined reservoir zone. The method supports computing the individual zone production histories of a commingled multi-layered reservoir. The data used in the analysis are used to construct the equivalent individual production histories. These individual completed interval production histories can then be evaluated as simply drawdown transients to obtain reliable estimates of the in situ reservoir effective permeability, drainage area, apparent radial flow steady-state skin effect and the effective hydraulic fracture properties, namely, half-length and conductivity.
