SEA-BED LOGGING MODELING USING COMSOL MULTIPHYSICS SOFTWARE: EFFECT OF DISPERSED CLAY AND BRINE SALINITY TO ELECTROMAGNETIC WAVE

This report basically discusses the preliminary research done and basic
understanding of the chosen topic,which is Sea-bed logging modeling using
COMSOL multiphysics from the near surface to as deep below the sea floor.
The objective of the project is to test the simulation using COMSOL
multiphysics software to be closed to the actual situation in the offshore rather than
use the electromagnetic wave to directly detecting the presence of oil and gas
reservoirs in exploration prospects prior to drilling. The challenge in this project is to
learn how to use the COMSOL multiphysics software.
The simulation using COMSOL will be done after solid modelling which is
reproduce the demonstration of the sea-bed logging modeling and continue to define
the properties of the sea-bed logging.F or the last step the analysis from the result
graph will be determine to get the exact prove that by using the simulation can be
similar to the actual situation in the offshore.
The experiment of the salinity of brine in a sand-shale reservoir rock also
affects the EM response considerably and studied the effect of varying the brine salinity.
Thus, modeling of SBL under control environment using suitable Electromagnetic
(EM) modeling technique to differentiate between water, sediment, and hydrocarbon
layer plane are needed.
The potential of this integrated modeling approach was demonstrated by
calculating the variation in the EM response associated with a petroleum reservoir,
due to different clay distributions ..
