Abstract
A visualization application will generate a Virtual Core representing a compilation of any formation property data, the compilation being a 2 and 1/2 D representation of any formation property. The compilation is generated by creating, in response to an integrated formation evaluation in 1D, a 2 and 1/2 D representation of each 1D formation property in the 1D formation evaluation, when the 1D property can be related to the 2 and 1/2 D physical magnitude combining the 2 and 1/2 D physical magnitude image with the 1D facies log thereby generating a 2 and 1/2 D facies image. The Software will also generate a Virtual Plug representing an average estimate of all formation properties over a prescribed surface or volume in the vicinity of a selection made on the compilation (i.e., on the Virtual Core). When an interaction with the Virtual Core occurs, all results generated by those interactions will be restored.
