A part of Petroleum Industry related to exploration and and production of of hydrocarbons (also called called Exploration & Production or or E&P).
The key elements of Upstream is Petroleum Reservoir and Petroleum Well, often considered in the context of Well-Reservoir System (WRS).
The size, structure and complexity of Petroleum Reservoirs are normally characterized by the generally accepted metrics on Reserves Classification.
The engineering part of Upstream operations is called Petroleum Engineering which It is essentially based on the knowledge area of Petroleum Geology and other Subsurface Production Disciplines.areas of:
The primary subject of E&P is exploring or acquisition of Petroleum Asset and maintaining the profitable production from it.
The results of the exploration lead to the procedure of Booking Reserves

exploration of a new or acquisition of existing Petroleum Assets and maintaining a profitable production from them.
The E&P activities are managed by Petroleum Operating Company with the help of Oilfield Services (OFS) and also undertake:
- searching, evaluating and acquiring the new Petroleum Assets
- 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:
