A part The area of Petroleum Industry dealing with subsurface exploration, drilling and production of hydrocarbons.
Drilling is split into exploration drilling and production drilling which have some specifics.
Production is usually split into Surface and Subsurface.
This basically leads to the two major components of Upstream industry:
and
Production
( see also Upstream @ Wikipedia )
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:
- 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:
