The size, structure and complexity of Petroleum Reservoir can be primarily assessed through the Reservoirs are normally characterized by the generally accepted metrics on Reserves Classification.

- selling existing Petroleum Assets in order to raise the funds for a more profitable investment opportunities
- making arrangements for Land allocation required for Petroleum Assets
The Upstream industry is split into two major operational areas: Petroleum Exploration and Petroleum Production:
