Production Hookup
IndustryThe final phase of connecting a well or facility to live production infrastructure, including pipelines, separators, and metering equipment. For subcontractors, it typically means intensive, time-sensitive scope with strict sequencing requirements. Delays can trigger penalties, making accurate scheduling and crew readiness critical.
Refined Products Pipeline
IndustryA pipeline system that transports processed petroleum products — such as gasoline, diesel, and jet fuel — from refineries to distribution terminals. Subcontractors are commonly mobilised for inspection, maintenance, and integrity work on these lines. Strict product contamination and safety protocols apply, requiring up-to-date certifications.
Waterflood
IndustryA secondary recovery method where water is injected into a reservoir to push remaining oil toward producing wells. Subcontractors support waterflood projects through injection well services, pump maintenance, and water handling infrastructure. Work scope can be long-term, offering stable recurring contracts.
Directional Services
IndustrySpecialised drilling support that steers a wellbore along a planned trajectory rather than straight down. Subcontractors provide MWD (Measurement While Drilling) tools, mud motors, and on-site directional drillers. These crews are typically mobilised on a per-well basis under dedicated service contracts.
Progressive Design-Build
IndustryA 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.
Leasehold
IndustryLand or mineral rights an operator has legally secured through a lease agreement with the landowner or Crown. Subcontractors typically work within leasehold boundaries, so access, permitting, and site rules are set by the operator holding the lease. Understanding leasehold limits helps crews avoid trespassing on adjacent unlicensed areas.
