A secondary oil recovery method where water is injected into a reservoir to maintain pressure and push oil toward production wells. Subcontractors support injection well drilling, pump installation, pipeline tie-ins, and ongoing facility maintenance. Scopes are often long-term, requiring sustained crew availability and specialised equipment.

Geosteering
IndustryThe real-time technique of guiding a drill bit through a target formation using geological data. Subcontractors supporting drilling operations may be called in on short notice as geosteering decisions change well paths. Expect scope adjustments and rapid crew or equipment mobilisation when geosteering is active.
Production Shut-in
IndustryA temporary halt to oil or gas production at a well or facility, ordered by the operator. For subcontractors, this often means suspended work orders and delayed revenue until operations resume. Standby rates and demobilisation terms in your contract become critical during a shut-in.
Life Extension Drydock
IndustryA scheduled out-of-water inspection and refit that extends a vessel's certified operational life beyond its original design limit. For subcontractors, it signals a concentrated burst of multi-trade work including hull repairs, coating, and systems upgrades. Scopes are often fast-tracked, creating strong short-term demand for specialised labour and materials.
Stock Hole
IndustryA pre-drilled or existing borehole kept in reserve for future use on a wellsite. Subcontractors may be mobilised to maintain or re-enter stock holes with little advance notice. Knowing a site has stock holes helps crews plan equipment and standby requirements.
Well Pairs
IndustryTwo horizontal wells drilled together — one injector, one producer — used in SAGD (Steam-Assisted Gravity Drainage) operations. Subcontractors often mobilise crews and equipment to service both wells simultaneously. Expect back-to-back work scopes and coordinated scheduling across a shared pad site.
ILI (In-line Inspection)
IndustryA pipeline integrity assessment using instrumented tools (smart pigs) run through the line to detect corrosion, cracks, or defects. Subcontractors are often mobilised for pig launching, data collection, and follow-up dig verification work. ILI campaigns can drive significant short-notice field service demand.
