The Complete Guide to Upstream, Midstream, and Downstream Oil and Gas Operations

The journey from oil and gas exploration to consumer consumption involves a complex and interconnected set of processes known as the three segments of the oil and gas industry. Understanding these segments, commonly referred to as upstream, midstream, and downstream, is essential for stakeholders and investors alike.

Upstream: Exploration and Production

The upstream segment encompasses the exploration and production of crude oil and natural gas. Companies in this segment locate and extract hydrocarbons from underground reservoirs using techniques such as drilling, well completion, and reservoir management. According to the International Energy Agency (IEA), global upstream investments reached $420 billion in 2022.

Key Companies in the Upstream Segment

Success Story: Royal Dutch Shell's Deep-Water Exploration

Royal Dutch Shell's pioneering efforts in deep-water exploration led to the discovery of the giant Bonga oil field in Nigeria. The field has produced over 1 billion barrels of oil since its inception, significantly boosting Shell's upstream production.

Midstream: Transportation and Storage

The midstream segment involves the transportation and storage of crude oil, natural gas, and refined products. Companies in this segment operate pipelines, terminals, and storage facilities to move hydrocarbons from production sites to refineries and distribution centers. The midstream market is expected to grow at a CAGR of 6.5% from 2023 to 2030, driven by rising global energy demand.

Key Companies in the Midstream Segment

Success Story: Kinder Morgan's Permian Pipeline Expansion

Kinder Morgan's Permian Pass Pipeline project is a major midstream development that transports natural gas from the prolific Permian Basin to the Gulf Coast. The pipeline expansion has increased the company's takeaway capacity and enhanced its position as a leading natural gas transporter.

Downstream: Refining and Marketing

The downstream segment includes refining crude oil into usable products such as gasoline, diesel, and petrochemicals, as well as marketing and distributing these products to consumers. Companies in this segment operate refineries, retail stations, and petrochemical plants. The global downstream oil and gas market is projected to reach $3.5 trillion by 2027, driven by increasing demand for refined products.

Key Companies in the Downstream Segment

Success Story: ExxonMobil's Downstream Expansion

ExxonMobil's acquisition of InterOil Corporation in 2015 significantly expanded its downstream footprint in Papua New Guinea and the Asia-Pacific region. The deal solidified ExxonMobil's position as a leading integrated oil and gas company with a strong global downstream presence.
