Image Log interpretation

Interpretation of micro-resistivity and of ultrasonic borehole images logs is a cornerstone of our services. Using  Image Log software we interpret fractures, in-situ stress indicators and lithofacies. We supply results which underpin fracture models and support appraisal activities such as selection of perforation or testing intervals.borehole image log

The image logs are an important instrument useful to characterize, in geological terms, the different reservoirs, in particular over un-cored intervals or when standard electric logs do not work properly or they are unable to help in a detailed reservoir characterization. Image logs can supply not only a geometrical information (3D distribution: azimuth, spacing…) of the features that cross the borehole (structural, sedimentological and diagenetic) but also a geological insight into the reservoir geology.

The main objectives of this interpretation are:

  • The interpretation of the main depositional and structural features that can be observed in the image log;
  • Perform a statistical analysis of the distribution of the interpreted features (to identify trends or geological characteristics);
  • Identify and characterize the different trends and try to understand the present day stress field.
