Holistic Approach to Determine Wellbore Fracture Density

Availability of well core is very valuable in fracture characterization. This information combined with borehole images (BHI) and CT scans allow a detailed analysis of fracture density distribution of one or multiple facies of a reservoir across different scales.

An example of such methodology is presented and highlights the uncertainty associated with the characterization of fractures interpreted from BHI as well as the need for their calibration with fractures on core and fractures identified on CT images. The concept of Image Quality factor is discussed.
