Acquisition and Interpretation of Open Hole Logs

Details :

The course covers the fundamentals of the acquisition and interpretation of open hole log data up to intermediate level. It presents the principles underlying the measurement of various properties of rock sequences penetrated in boreholes and covers both the qualitative and quantitative interpretation of the data obtained. It also discusses the recent advances in log data acquisition technology.

 Acquisition and interpretation of dipmeter and formation image log data are also covered.


Geoscientists and petroleum engineers with little or no experience of petrophysics. It serves also as an update for more mature operators in this field.
