Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Perforate

To create precisely spaced holes or openings in oil well casing and cement at a target formation depth, allowing hydrocarbons to flow into the wellbore; subcontractors providing perforating services typically work under wireline or coiled tubing crews and must coordinate closely with the operator's completion schedule.

Related Terms

Royalty Rate

Industry

The percentage of resource revenue an operator pays to the Crown or landowner before profits are calculated. High royalty rates can reduce operator budgets, directly affecting subcontractor hiring and field service spending. Understanding local royalty structures helps subcontractors anticipate project volumes and client cash flow.

Completions

Industry

The phase of oil and gas well development after drilling is finished, encompassing the work required to prepare a well for production — including perforating, fracturing, and installing wellhead equipment. For subcontractors, completions represent a concentrated burst of high-demand field work where specialised crews, equipment, and services are mobilised under tight timelines.

Upstream Tie-in

Industry

A connection point where new pipeline or equipment is integrated into an existing live system closer to the wellhead or source. For subcontractors, this work typically requires strict hot-work permits and precise scheduling around production shutdowns. Delays at tie-in points directly impact your crew's standby time and invoice milestones.

Exploratory Well

Industry

A well drilled in an unproven area to determine whether hydrocarbons are present, typically representing higher-risk, shorter-duration work for subcontractors with less certainty of follow-on contracts compared to development drilling programmes. Field service companies should account for the speculative nature of these projects when negotiating mobilisation costs and contract terms.

Lifecycle-Based Approach

Industry

A method of planning services, maintenance, or contracts around the full lifespan of an asset or project phase. Subcontractors use it to align scopes of work, pricing, and resource deployment from mobilisation through decommissioning. This helps avoid scope gaps and supports longer-term service agreements.

Leasehold Acres

Industry

The total land area an operator has licensed to explore or produce hydrocarbons. Larger leasehold positions typically mean more sustained work for subcontractors across multiple well sites. It signals the operator's activity footprint and potential contract volume in a region.
