lntepretations of Porosity and Saturations for Sepat-X and Sepat-XSTl Wells Offshore Terengganu Using Radioactive and Resistivity Logs.

This report basically discusses the results of the research in understanding the chosen
topic, which is Interpretations of Porosity and Saturations for Sepat-X and Sepat-XSTl
Wells Offshore Terengganu Using Radioactive and Resistivity Logs. In this report, the
author has added the part of resistivity logging. Resistivity is the electrical resistance,
measured in ohms, is defined as the ability of a material or substance to obstruct the
flow of electrical current. Resistivity logging is crucial in calculating the fluid saturation
by providing the Rw (water resistivity) and the Rt (true resistivity) to be used in the
Archies' saturation equation.
The author has also made a comparison between the two methods of determining the
pretophysical properties such as porosity, water saturations and hydrocarbon
saturations from using the manual calculations and from using Interactive Petrophysics
(IP) software. The author had also dertemined the fluid contacts and the fluid type in
each sands.
