ABSTRACT
This paper reviews the basic electromagnetic field theory of microwave propagation and the techniques used to measure, process and interpret the data obtained with the Electromagnetic Propagation Tool (EPT).
The theoretical basis for an interpretation procedure for the EPT log is developed and the application of EPT derived porosity and apparent fluid resistivity to the Dual Water model is reviewed. The application of this interpretation model using the SCHLUMBERGER CYBER SERVICE UNIT (CSU) for processing is discussed and the formats of the CYBERLOOK wellsite processing are reviewed.
The application of this interpretation technique to fresh water, shaly, low gravity oil sands is discussed. Several examples are reviewed showing the comparisons between log computations and conventional core data.
