Subsurface fracture mapping using the Formation MicroScanner tool
- Schlumberger, Assago (Italy)
Fracture detection methods based on standard log measurements are often limited because none of these measurements has been designed to specifically address this problem. Therefore the position vs. depth, orientation, and aperture of the fractures cannot be determined without the help of full-sized cores, which cannot be taken in every well for economic reasons. A new solution to overcome these limitations is given by the oriented microresistivity images provided by the Schlumberger Formation MicroScanner tool (FMS). The comparison between FMS images and real cores confirms the tool can be run extensively in a field for facies zonation and fracture identification. Computer-aided analysis enables recognition and orientation of the fractures. Subsequently, a statistical analysis is applied to classify the different families of fractures. In fractured reservoirs the results permit precise definition of the main permeability paths and the tectonic history of the formation.
