Patent ID: 6963803

Claim:
A method of determining a physical characteristic associated with a plurality of layers of a laminated formation traversed by a wellbore, said method comprising the steps of: providing one or more high resolution logs of a formation property for the laminated formation; from a high resolution log, detecting the bed boundaries of the laminated formation, thereby detecting the individual beds disposed between the boundaries; importing a set of defined facies associated with the laminated formation, including importing a volumetric description with each of the defined facies; assigning one of the defined facies, and the volumetric description associated therewith, to each of the beds detected; generating at least one squared log for a formation property, including using imported volumetric descriptions of the facies for a plurality of beds to generate a value of the formation property for each of the beds; comparing the squared log with a measured log of the formation property for the laminated formation; adjusting the values of the squared log; and repeating, one or more times, said adjusting and comparing steps before selecting an adjusted squared log as an optimized square log of the formation property.
