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.
The engineering part of Upstream operations is called Petroleum Engineering which is essentially based on the knowledge areas of:
| Surface E&P Disciplines | Subsurface E&P Disciplines | Data Acquisition |
The primary subject of E&P is exploration of a new or acquisition of existing Petroleum Asset and maintaining a profitable production from it.
The Upstream industry is split into two major operational areas: Petroleum Exploration and Petroleum Production:
Petroleum Industry (Oil & Gas Industry)
[ Petroleum Asset ] [ Petroleum Reservoir ] [ Petroleum Well ]
[ Well Drilling ] [ Surface E&P Disciplines ] [ Subsurface E&P Disciplines ] [ Data Acquisition ]
