Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Leasehold Acres

The total land area an operator has licensed to explore or produce hydrocarbons. Larger leasehold positions typically mean more sustained work for subcontractors across multiple well sites. It signals the operator's activity footprint and potential contract volume in a region.

Related Terms

PWHT (Post-weld Heat Treatment)

Industry

A controlled heating and cooling process applied to welds after completion to reduce stress and improve strength. Subcontractors must confirm PWHT requirements before mobilising, as it adds time, equipment, and certified personnel to scope. Failing to price it into your bid can significantly erode job margins.

Value Stream Mapping

Industry

A visual tool that diagrams every step in a field service workflow, from job award to final invoice. It helps subcontractors identify delays, waste, and bottlenecks in their operations. Teams use it to streamline mobilisation, work execution, and billing cycles.

Suspension Order

Industry

A formal directive from a prime contractor or operator to halt work on a project temporarily. Subcontractors must stop billable activities but may still incur standby costs. Review your contract carefully, as suspension terms affect demobilisation, remobilisation, and delay compensation.

Integrated Project Delivery (ipd)

Industry

A project delivery model where owners, contractors, and subcontractors share contracts, risks, and rewards from early design through completion. Subcontractors are brought in earlier than traditional models, giving more input on planning and scheduling. Compensation is often tied to collective project outcomes rather than individual scope performance.

CSG (Casing)

Industry

Steel pipe installed in a wellbore to provide structural integrity and prevent contamination between different geological formations, requiring specialized installation and cementing services that subcontractors frequently provide during drilling operations.

FFS (Fitness-for-service)

Industry

A structured engineering assessment that determines whether ageing or damaged equipment is safe to keep operating. Subcontractors are often hired to collect inspection data, run integrity tests, or execute repairs recommended by FFS evaluations. Understanding FFS scope helps field crews prioritise work orders and meet client fitness thresholds before returning assets to service.
