Intepretations of Porosity and Saturations for Sepat-X and Sepat-XST1 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-XST1 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.
