Description
Summary:Seabed logging, SBL is an application of marine control source electromagnetic, CSEM sounding which can deliver a near perfect direct hydrocarbon indication. Thus, UTP has developed the simplified sea model measurement facility and current source for sea bed logging from their 2008 Final Year Project program; it was found that the receiver was not sensitive enough to pick up magnetic field signal. Therefore, improvement has to be carried out at the receiver to improve data acquisition of the magnetic fields for the scale sea model. By doing so, more reliable magnetic fields signal can be pickup which later will improve overall system in magnetic field measurement specific. This project was carry out with objectives to improved magnetic field receiver sensitivity, to integrate newly develop magnetic receiver to the scale sea model, to map magnetic field in the scale sea model and to analyze received signal from the mapping process. From the calibration process it is observed that the resistivity of magnetic receiver have capability to detect as low as 0.01 micro-Tesla as improvement from mili-Tesla range from previous setup and also magnetic field mapping process has shown promising result in finding buried object.
