Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Remote-Site Services

Work performed at isolated locations far from urban centres, such as camps, wellsites, or pipeline corridors. Subcontractors must self-manage logistics, including equipment, consumables, and crew rotations. Mobilisation costs and travel time significantly affect how contracts should be priced.

Related Terms

GOR (Gas-oil Ratio)

Industry

GOR measures the volume of gas produced relative to each barrel of oil at a well site. A rising GOR signals changing well conditions, which can affect equipment requirements and scope of work for field service crews. Subcontractors should monitor GOR shifts, as they may trigger additional service calls or changes to compression and separation equipment needs.

Hydrotesting

Industry

A pressure test using water to verify the integrity of pipelines, vessels, or equipment before commissioning. Subcontractors are often scoped separately for hydrotest labour, equipment, and water disposal. Confirm whether these costs are included in your contract or billed as extras.

Production Shut-in

Industry

A temporary halt to oil or gas production at a well or facility, ordered by the operator. For subcontractors, this often means suspended work orders and delayed revenue until operations resume. Standby rates and demobilisation terms in your contract become critical during a shut-in.

MCF (Thousand Cubic Feet)

Industry

Standard unit for measuring natural gas volumes, equal to 1,000 cubic feet. Subcontractors use MCF to interpret production targets, scope work, and align service pricing on gas well projects. Billing rates and throughput bonuses are often tied directly to MCF volumes.

TOFD (Time-of-flight Diffraction)

Industry

An ultrasonic weld inspection method used to detect and size internal flaws in pipelines and pressure vessels. Subcontractors performing NDT work must hold TOFD-specific certifications to qualify for this scope. It is widely accepted by regulators as an alternative to radiographic testing.

VRU (Vapour Recovery Unit)

Industry

A compression system that captures hydrocarbon vapours from storage tanks or production equipment instead of venting them. Subcontractors are often hired to install, maintain, or service VRUs to meet emissions regulations. Familiarity with VRU work is increasingly required on oil and gas production sites.
