Abstract:
In the present time, the economy of the world is being controlled by the energy sector. The energy resources and reserves are being used as indicators of the economy and political stability of a country. Petroleum and related energy reserves of a country
constitute its most important assets. The role of hydrocarbon availability, exploration, and development is directly related to the overall development and prosperity of the human being.
Petroleum exploration and its exploitation have gained special importance over the past few decades to meet the increasing demand of world energy. Due to its importance, this field has developed special interests of the scientists and various
hydrocarbon agencies and a number of new geophysical techniques and methods have been developed to explore and exploit the hydrocarbon buried in subsurface geological formations. Geophysical well logging is one of the strong tools that are used to
evaluate the formation of characteristic features having the potential for hydrocarbon development. Well logging, also known as borehole logging is the practice of making a detailed record (log) of the geologic formations penetrated by a borehole. The log may
be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs). Well logging is done when drilling boreholes for oil and gas, groundwater, and minerals, and for environmental and geotechnical studies.
