A rapid review of the energy resources situation in the world today shows the important role that oil and gas play in human life. World economies will continue to rely on oil and gas as a major energy source. It is absolutely critical that policy makers-governments, investment decision makers, and oil companies-cooperate in securing a supply of energy for future generations. The international oil industry, in its sustained efforts to optimize resources in a cost-conscious and challenging environment, has been working under several constraints : reduction in investments, environmental issues and policies, and workforce optimization. This paper highlights recommendations for facing these challenges.
