ILI (In-line Inspection)

Related Terms

Permitting Reform

Industry

Changes to government approval processes that reduce delays for energy and construction projects. Faster permits mean earlier mobilisation and more predictable project timelines for subcontractors. This can directly affect when crews and equipment are scheduled and when work orders are issued.

Directional Drilling

Industry

A drilling technique used to steer a wellbore along a non-vertical path to reach a target zone. Subcontractors supporting these operations often require specialised tooling, MWD (Measurement While Drilling) equipment, and certified directional hands. Scopes can shift quickly, so flexible crew and equipment mobilisation is essential.

Distributed Fibre-Optic Sensing

Industry

A monitoring technology that uses fibre-optic cables as continuous sensors along pipelines, wellbores, or structures. It detects temperature, strain, and acoustic changes across kilometres of cable in real time. Subcontractors may be hired to install, splice, or maintain these cable systems during construction or integrity projects.

High-Impact Well

Industry

A well with significant technical complexity, cost, or strategic value to the operator. For subcontractors, these projects typically involve stricter oversight, specialised equipment, and higher performance expectations. Mobilisation windows and crew qualifications are often scrutinised more closely.

Tank Farm

Industry

A designated site containing multiple large storage tanks for oil, gas, or chemicals. Subcontractors frequently perform inspection, maintenance, and cleaning work at these facilities. Access permits and confined space certifications are typically required on site.

Field Ticket

Industry

A document created in the field that records work performed, equipment used, materials consumed, and time spent. Field tickets are the basis for invoicing and must typically be approved by the customer before payment.
