Fracture morphology in Cretaceous carbonate reservoirs from south-east Turkey

The aim of this article is to demonstrate the measurements of the degree of fracturing and the orientation of the natural fracture systems within reservoir units by using electrical (FMS) and acoustic (BHTV) images. Borehole imaging is an economical method of evaluating the distribution of reservoir porosity systems, especially fractures, in the sub-surface. Along with accurate orientation of the fracture events, a calculation can now be made of fracture aperture, density and porosity, both vertically and horizontally in the region of the wellbore. This is performed after calibration of the image data to a Laterolog Shallow or Spherically Focused resistivity measurement.
