Abstract

Exploration of hydrocarbons in the sea is particularly expensive because it is best done by supplying a transmitter with a strong current, which is hazardous to the lives of marine life. A steady supply of voltage and current to the transmitter is normally used to determine the strength of electromagnetic waves. The mineral deposition has been detected using different techniques, both offshore and onshore. Detection of minerals by employing a controlled source electromagnetics (CSEM) has recently proved to be extremely effective with yielding promising results. Due to noise, both the transmitted and received signals may differ. The signal received from the subsurface in marine settings is generally limited by a variety of noise. The frequency spectrum of frequency signals and waveforms change when they interact with physical objects. Understanding how the frequency spectrum is altered allows us to examine how the signal and waveforms change. To accurately evaluate and eradicate these noises, they must be researched and taken into consideration. One of the most challenging problems employing Marine CSEM (MCSEM) in the detection of hydrocarbon is airwaves. When an electromagnetic ...
