The Chad/Cameroon development project includes oilfields in southern Chad and a pipeline system to transport crude oil to a marine terminal in Cameroon for export. The objective of this project is to fight against poverty by improving the living condition of Chadian population. The exploration and production of the Chadian oil is operated by a Consortium consisted of ExxonMobil, Petronas, and Chevron with a western dominant culture. As a result, the project has created vast numbers of new jobs but led at the same time to powerful social changes, especially cultural and political conflicts that arise. In this context, to merge the national culture within the company remains a real challenge. Our exclusive focus here is to explore the differences and similarities between the two cultures in the Doba oil field in Chad.
