Borehole Imaging Interpretation
- Upon completion of the course, participants will be able to:
- acquire the fundamental principles of Borehole Image Interpretation,
- apply the methodology to approach the Borehole Image Interpretation,
- perform BHI data quality control,
- identify the fractures present in the images, by differentiating them from sedimentary and artificial features,
- characterize the interpreted fractures in terms of their position, morphology, type, kinematics, orientation and dip angle, using GEOLOG.
Geoscientists and reservoir engineers are involved in the development of naturally fractured reservoirs.
