Key Reference

Objective of Production Engineering:To maximize well productivity considering :

• Cost effectiveness• Safety

Overview of a Petroleum Production Unit

The petroleum industry is usually divided into three major components: Upstream, midstream and downstream. Midstream operations are usually included in the downstream category.

UpstreamGas & Oil exploration and

production

DownstreamTreating, Selling & 

Distribution

The upstream sector includes the searching for potential underground or underwater oil and gas fields, drilling of exploratory wells, and subsequently drilling and operating the wells that recover and bring the crude oil and/or raw natural gas to the surface.

The downstream oil sector refers to the selling and distribution of natural gas and products derived from crude oil.Such products include liquefied petroleum gas (LPG), gasoline or petrol, diesel oil, kerosene, fuel oil, asphalt, etc.

Upstream: Term commonly used to refer to the searching for and the recovery and production of crude oil and natural gas. The upstream oil sector is also known as the exploration and production (E&P) sector.

Midstream: Processes, stores, markets and transports commodities such as crude oil, natural gas, natural gas liquids (NGLs), and Liquefied Natural Gas (LNGs, mainly ethane, propane, and butane and sulphur.

Downstream: Term commonly used to refer to the refining of crude oil, and the selling and distribution of natural gas and products derived from crude oil.

s, The upstream oil & gas industry involves the extraction, recovery and delivery of energy sector products to so‐called ‘Downstream’ applications, where energy products are processed to make viable products.
