Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Load Growth

A gradual increase in power demand on a site's electrical system as more equipment and crews are added. Subcontractors must plan for load growth when sizing temporary power installations or generators. Failing to account for it can cause outages, project delays, and costly rework.

Related Terms

Progressive Design-Build

Industry

A project delivery method where design and construction phases overlap, with the owner and contractor collaborating before scope is fully defined. Subcontractors are often brought on early, meaning scope, pricing, and schedules can shift as design matures. Contracts may be cost-reimbursable at first, then convert to fixed-price once scope is confirmed.

PCP (Progressive Cavity Pump)

Industry

A rotary pump used in oil and gas production to lift heavy or viscous fluids from wellbores. Subcontractors are frequently hired for PCP installation, maintenance, and rod-string servicing. Familiarity with drive heads, stators, and rotors is essential for field technicians working these jobs.

Prospective Interval

Industry

A rock formation believed to contain oil or gas, targeted for drilling or evaluation. Subcontractors are often mobilised to support exploration work within these zones. Scope and duration of field service contracts may depend on how many prospective intervals a well will test.

EPC (Engineering, Procurement, Construction)

Industry

A project delivery model where one main contractor handles all phases from design to completion, typically creating multiple subcontracting opportunities for field service companies across different project phases. For subcontractors, EPC projects often mean working under a prime contractor who coordinates all trades and manages the overall timeline and specifications.

IMR (Inspection, Maintenance, and Repair)

Industry

A category of ongoing field service work covering routine inspections, preventive maintenance, and corrective repairs on infrastructure or equipment, often awarded to subcontractors through standing agreements or blanket contracts. For field service companies, IMR scopes provide a reliable stream of recurring work but typically require crews to mobilise quickly and hold multiple trade certifications to meet operator requirements.

GWD (Getting Work Done)

Industry

A safety and compliance management system used by some operators to pre-qualify and manage contractors working on their sites.
