Well Log Petrophysical Interpretation

Single or multiple well evaluations of open hole and cased hole logs are frequently performed by Naphtho petrophysicists to support due diligence, exploration, appraisal and development decisions.

Existing wells can be re evaluated using advanced methods to identify potential intervals of by passed pay due to low resistivity or thin beds effects.

Integrated Reservoir Evaluation

Full field integrated reservoir studies are undertaken to provide a consistent set of petrophysical parameters for the population of static and dynamic reservoir models.

Well log, core analysis , formation pressure and test data are integrated in an iterative evaluation to provide an optimized interpretation of reservoir properties and ranges.


Saturation-Height Functions derived from capillary pressure data are used to assess uncertainty in water saturations derived from log analysis.

Naphtho’s petrophysicists when requires uses Interactive Petrophysics (IP) and Techlog software packages. Naphtho’s petrophysicists and consultants are experienced users of all industry standard petrophysical packages.

Rock Physics

Specialized interpretations are performed jointly by the petrophysicist and geophysicist to derive seismic rock and fluid properties as input to AVO modelling, synthetic seismograms and inversion studies.

Operations Petrophysics Support

24/7 real-time formation evaluation and petrophysical support for well operations. Rapid turn around of log analysis results to support drilling and testing decisions.

Planning of cost effective logging, core analysis and testing programmes.

In House Software

Naphtho’s petroleum engineers and consultants when requires uses Petroleum Expert’s Prosper’ software allowing to model well bore pressures and flow rates.
