Abstract
A method of normalizing well log data relating to geology of a subsurface region includes identifying a pair of markers defining a zone on each well log, determining a statistic for a property within the zone for each well log, fitting a smooth function to the statistics to create a first-iteration trend surface, determining, for each statistic, a deviation from the trend surface and eliminating those statistics that deviate from the trend surface by greater than a threshold value, fitting a smooth function to the remaining statistics to create a second-iteration trend surface, normalizing the property for each well log based on the second-iteration trend surface, and analyzing the normalized properties to determine the geology of the subsurface region.
