Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

2c Resources

The middle estimate of contingent petroleum resources that are discovered but not yet approved for development. For subcontractors, 2C resource announcements often signal future project opportunities that are not yet fully funded. Bid opportunities tied to 2C resources carry higher uncertainty and may shift significantly before contracts are awarded.

Thermal In-Situ

Industry

A method of extracting heavy oil or bitumen by injecting steam underground to heat and mobilise the resource. Common techniques include SAGD (Steam Assisted Gravity Drainage) and CSS (Cyclic Steam Stimulation). Subcontractors support these operations through facility construction, pipefitting, instrumentation, and ongoing maintenance work.

FID (Final Investment Decision)

Industry

The point when a project owner formally approves funding and commits to proceeding with a major project. For subcontractors, FID is the trigger that converts preliminary work into confirmed scopes and purchase orders. Mobilisation planning, crew hiring, and equipment sourcing typically begin after FID is announced.

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.

Pipeline Tie-in

Industry

A pipeline tie-in is the physical connection of a new pipeline section to an existing live system. For subcontractors, tie-in work often requires hot-tap certified crews and strict isolation procedures. Scheduling is critical, as tie-ins typically involve planned shutdowns with tight production windows.

Land Block

Industry

A designated area of Crown or freehold land divided for exploration and production rights. Subcontractors often mobilise crews and equipment according to which land blocks an operator holds active licences for. Work scopes, access agreements, and surface rights are typically tied to specific block boundaries.

Membrane Separation

Industry

A filtration process that uses semi-permeable membranes to separate gases or liquids by molecular size or pressure. Common in natural gas processing and produced water treatment on field sites. Subcontractors may install, inspect, or maintain membrane units as part of facility service scopes.
