Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Infill Drilling

Drilling new wells between existing producers to recover bypassed reserves in a developed field. For subcontractors, it means shorter mobilisation windows and back-to-back well programmes. Expect high crew utilisation but tight scheduling with little downtime between jobs.

Related Terms

Midstream Infrastructure

Industry

The pipelines, compressor stations, and processing facilities that move and condition product between the wellhead and end markets. For subcontractors, it represents a major source of maintenance, construction, and inspection work. Contracts here often involve long project timelines and strict regulatory oversight.

Borrow Material

Industry

Soil, gravel, or fill excavated from one location and transported to another for grading or earthwork. Subcontractors may need to source, haul, and place borrow material as part of site prep scopes. Confirm who supplies and pays for it before signing your contract.

Long-Cycle Project

Industry

A major capital project with a development timeline spanning several years, such as an LNG (Liquefied Natural Gas) facility or oilsands expansion. For subcontractors, these projects can offer extended contract opportunities but require careful cash-flow planning. Mobilisation costs and payment schedules must be negotiated carefully, as revenue is spread over a long horizon.

Alternative Delivery

Industry

A project procurement model where design and construction are bundled under one contract, such as design-build or EPC. Subcontractors often engage through a prime contractor rather than directly with the owner. Scope, risk, and payment terms can differ significantly from traditional bid-build arrangements.

Transmission Planning

Industry

The long-term process of designing and expanding power grid infrastructure to meet future energy demand. For subcontractors, it drives project pipelines for line construction, right-of-way clearing, and equipment installation. Winning transmission work often requires early engagement with utilities and grid operators.

Wet Utilities

Industry

Underground systems that carry water, sewage, or other liquids, including water mains, storm drains, and sewer lines. Subcontractors must locate and mark these lines before any excavation to avoid costly damage or work stoppages. Wet utility work often requires specialised crews and municipal permits.
