Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Rental Power

Temporary generator or mobile power units leased for a job site instead of purchased outright. Subcontractors use rental power when permanent grid connections are unavailable or impractical. Costs are typically passed through to the client or built into the project bid.

Related Terms

Closed-Loop Heat Exchanger

Industry

A sealed system that transfers heat between two fluid circuits without them making direct contact. Subcontractors service these units for cleaning, inspection, and pressure testing. They are common in oilfield facilities, compressor stations, and industrial construction sites.

MOU (Memorandum of Understanding)

Industry

A non-binding agreement outlining the intent to work together before a formal contract is signed. Subcontractors use MOUs to secure preferred vendor status or reserve capacity for upcoming projects. They carry no payment guarantee, so avoid mobilising resources based solely on an MOU.

Gigafactory

Industry

A large-scale manufacturing facility producing batteries or energy components, often for EV or renewable projects. These sites generate major subcontracting opportunities in electrical, civil, and mechanical trades. Expect large crew mobilisations, tight schedules, and industrial construction workflows.

Gathering Infrastructure

Industry

The network of pipelines, compressors, and processing facilities that collect hydrocarbons from wellheads and move them to processing or transmission points. For subcontractors, it represents a major source of construction, maintenance, and inspection work. Projects often run concurrently with drilling programmes, creating tight scheduling demands.

Boe/d (barrels of Oil Equivalent Per Day)

Industry

A standard measure of a well site's or facility's total energy output, combining oil, gas, and NGLs into one comparable unit. Operators use BOE/D figures to size projects and determine crew and equipment requirements. Higher BOE/D rates typically signal larger scopes of work and longer service contracts for subcontractors.

Mmcf/d (million Cubic Feet Per Day)

Industry

A measurement of natural gas production or flow volume, used to describe the output capacity of a well, pipeline, or facility. Subcontractors use this figure to gauge job scale, equipment sizing, and crew requirements. Higher MMcf/d ratings typically signal larger scopes of work and longer contract durations.
