Industry Glossary Term

Schedule Compliance

A measure of how consistently a subcontractor completes work within the agreed timeline. Low compliance can trigger penalties, delay progress payments, or affect contract renewal. Tracking it helps field crews identify where mobilisation or scope changes are causing slippage.

Related Terms

Tight Gas

Industry

Natural gas trapped in low-permeability rock formations that require hydraulic fracturing or horizontal drilling to extract. For subcontractors, tight gas projects typically involve intensive well stimulation work and longer mobilisation cycles. Expect higher equipment demands and specialised crew certifications on these sites.

Aggregates

Industry

Crushed stone, gravel, and sand used as base materials in construction and oil and gas site preparation. Subcontractors sourcing or hauling aggregates must account for material costs, transport, and site access conditions. Pricing and availability vary significantly by region and project remoteness.

Takeaway Capacity

Industry

The available pipeline, trucking, or rail infrastructure to move produced oil, gas, or water away from a wellsite or facility. When takeaway capacity is constrained, operators may shut in wells or delay projects, directly reducing field service work volumes. Subcontractors should monitor regional takeaway conditions as they signal upcoming slowdowns or surges in activity.

Vam Connections

Industry

Premium threaded pipe connections used in oil and gas drilling and completion operations. Subcontractors handling, installing, or inspecting VAM connections must follow strict torque specs and handling procedures. Improper makeup can result in costly downhole failures and liability exposure.

Grid Interconnection

Industry

The process of connecting a power generation asset to the public electrical grid. For subcontractors, it triggers specific commissioning milestones, inspections, and sign-offs. Delays in interconnection approval can directly impact project timelines and invoicing.

Crane Mats

Industry

Large interlocked timber or composite panels placed under crane outriggers to distribute load on soft or unstable ground. Subcontractors often supply, transport, and install them as part of site prep scopes. Rental and mobilisation costs should be clearly itemised in your quote.
