A part of Petroleum Industry dealing with related to exploration and and production of of hydrocarbons (also called Upstream)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 It is essentially based on the knowledge area of Petroleum Geologyareas of:
The primary subject of E&P is exploring or purchasing Petroleum Asset and maintaining the profitable production from it
...
Exploration drilling
Open-Hole surveys:
Acoustic logging
Vertical seismic profiling
Gamma density logging
Formation resistivity logging
Neutron logging
Formation testing
Cased-Hole surveys:
...
Laboratory analysis:
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:
