Open Hole Log Interpretation: Istanbul


Open Hole Log Interpretation: Istanbul

Course overview

The course will introduce the participants to the Basis of Petrophysics, and Open-hole Log Analysis and Formation Evaluation, which is one of the basic disciplines in petroleum exploration and production.

The course is designed for

Exploration Geologists

Production Geologists

Exploration Managers

Well-site Geologists

Operations Geologists



Well Data Managers



Learning objectives

To undergo a review of open-hole logging tools as well as the measurements made by the logging toolsTo undertake the transformation of the measured data into useful reservoir parameters such as porosity, permeability, water saturation and reserve estimations.To understand the link or relation between Petrophysics, Seismic interpretation, Seismic Reservoir Characterisation and Reservoir Modelling.
