1.0 INTRODUCTION
The oil and Gas industry is one of the largest and most important
global industry, there are
various activities that must take place to transform inputs of raw materials, knowledge, labor
and capital into end products purchased by customers. A value chain
is a device that helps
identify the independent, economically viable segments of an industry. Value refers to what
customers are willing to pay for, and so the value chain helps to identify the specific activities
that create value throughout the chain the Oil and Gas industry.
The oil and gas industry is divided into three major sectors:
upstream, midstream and
downstream.
In this project the segment to be discussed is the Upstream
segment of the Oil and Gas
Industry.

The upstream oil sector is also commonly known as the exploration and production (E&P).
The upstream sector includes the searching for potential underground or underwater crude oil
