Patent ID: 8515721

Claim:
A method for determining rock and fluid properties of a fluid-containing subsurface geological formation, comprising: creating an initial, low resolution model of the geological formation from an initial lumped average parameter estimation derived from at least fluid pressure transient data obtained at selected points along a linear wellbore that traverses the formation; creating a coarse scale grid-based parameter estimation model of the geological formation by combining the initial, low resolution model with data from at least one of seismic test results, formation logs, or basic geological structural information surrounding the linear wellbore; creating a finer scale grid-based parameter estimation model of the geological formation in one or more selected areas of the coarse scale grid-based parameter estimation model by obtaining additional data at points within the geological formation and combining the resulting additional data points with the coarse scale grid-based parameter estimation model; creating a structural model of the geological formation from the finer scale grid-based parameter estimation model by using geostatistical realization methods that are constrained by dynamic data points; simulating from the structural model a simulated lumped average parameter estimation along the linear wellbore, and comparing the simulated lumped average parameter estimation with the initial lumped average parameter estimation to determine a confidence level in the structural model.
