Downstream & Upstream

"Downstream" refers to all activities after oil production, including transportation, processing and distribution of petroleum products. "Upstream" comprises the geological exploration and extraction of crude oil until it is made available in purified form.

Definition
"Downstream" is a term used in the petroleum industry to describe the operations that follow the refining and distribution of petroleum products. In contrast, "upstream" covers the entire process from geological exploration to the extraction of crude oil.

Background / Origin
The terminology "downstream" originates from hydropower utilization, where "downstream" describes the subsequent phase. In the petroleum business, it refers to all the steps that follow crude oil production (upstream). The downstream area is often subdivided into "midstream", which covers the transportation between the two areas.

Historically, the separation between upstream and downstream arose from the needs of consuming countries that wanted to create a dependency on producing countries. This led to the creation of effective and extensive transportation and distribution networks.

In the upstream sector, the focus is on geological analysis and exploration using modern technologies such as reflection seismics and drilling. These techniques enable the identification of suitable deposits and the determination of oil quality and quantity.

Features
The downstream sector includes several services:
- Transportation: movement of petroleum products to consumer markets.
- Processing: refining of crude oil to produce various products.
- Distribution: Sale of processed petroleum products to end customers.

Specialized technologies are used in the upstream sector, including
- Horizontal directional drilling
- Data measurement during the drilling process (MWD - Measurement While Drilling)
- Software for data analysis
- Construction of drilling motors

The technology has developed continuously, but remains cost-intensive and risky.

Application and significance in the market
Downstream operations are crucial for supply chain management, whereby the efficient handling of large quantities of mineral oil, which amount to around 3.5 billion tons per year globally, is central. The entire process from transportation and storage to distribution is of high strategic importance for oil companies.

The upstream sector plays an equally important role in ensuring the availability of raw materials by creating the conditions for oil production. Geological analyses and exploration are crucial to success here.

Differentiation from similar terms
- Downstream: Includes transportation, processing and distribution after oil production.
- Upstream: Includes geological development, transportation to the surface and the supply of crude oil.
- Midstream: Can be seen as an intermediate segment covering transportation between upstream and downstream.

Summary
"Downstream" refers to all operational areas after oil production, while "upstream" covers the entire process from exploration to crude oil production. The separation of these terms is historical and based on the needs of the consuming countries. The sector is crucial for supply chain management and includes critical technologies to meet the challenges in the oil industry.
