A part of Petroleum Industry related to exploration and production of hydrocarbons (also called Exploration & Production 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 is essentially based on the knowledge areas of:


The primary subject of E&P is 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:

The Upstream industry is split into two major operational areas: Petroleum Exploration and Petroleum Production:
