Classical Image Interpretation

HRP performs conventional borehole image interpretation. Generally this interpretation involves structural interpretation and paleocurrent interpretation.


The structural interpretation is designed to identify the structural dip of the formations as well as any faults , fractures, breakout and other features useful in helping understand the structural emplacement of the rocks and what makes the particular location good or bad for hydrocarbon accumulation.

The problems solved by this interpretation is summarized below:

HRP has undertaken large multi well studies such as over Elk Hills The value of these studies is as follows:

  • Detailed understanding of fracture frequency

  • Detailed understanding of fracture width

  • Large database of information that can be integrated and related to production.

  • Use of mapping techniques to allow inter and intra-well decisions to be made

The studies yielded information that allowed vertical and lateral relationships with fractures to be predicted and used across the field.

In integrating depositional picks HRP uses a standard schema and studies have yielded

  • Direct relationship between permeability and paleo depositional environment.

  • Interaction of fractures and fracture permeability with depositional environment. 

  • Direct integration with production information.
