Industry Glossary Term

Upstream

The segment of the oil and gas industry involved in exploration and production (E&P). Includes drilling, completions, and well operations.

Related Terms

Downhole Tools

Industry

Specialised equipment run into a wellbore to perform drilling, measurement, or completion tasks. For subcontractors, these tools often require certified handling, transport, and make-up procedures. Improper use can trigger costly liability or contract disputes.

LNG (Liquefied Natural Gas)

Industry

Natural gas cooled to -162°C to become liquid for easier transport and storage, creating specialized work opportunities for subcontractors in cryogenic equipment maintenance, pipeline construction, and terminal facilities that require specific safety certifications and cold-weather expertise.

Core Desorption

Industry

A lab process where gas is measured as it releases from rock core samples pulled during drilling. Subcontractors handling or transporting cores must follow strict protocols to preserve sample integrity. Mishandling can compromise data and trigger costly disputes with operators.

Brent Crude

Industry

A globally traded North Sea oil benchmark used to set crude pricing contracts. When Brent prices rise or fall sharply, operators often adjust project budgets, affecting subcontractor work volumes and day rates. Monitoring Brent helps field service companies anticipate slowdowns or ramp-ups in awarded work.

Lease Road

Industry

A temporary or permanent access road built to service an oil and gas lease or well site. Subcontractors are often responsible for maintaining or mobilising equipment over these roads. Road conditions directly affect trucking rates, equipment wear, and scheduling.

SPR (Strategic Petroleum Reserve)

Industry

A government-held emergency stockpile of crude oil that, when released or replenished, can trigger short-term surges in drilling, transportation, and maintenance contracts as operators respond to shifting supply directives. Field service companies should monitor SPR activity as an indicator of near-term work mobilisation and pricing conditions in their region.
