Easement

A natural gas liquid (NGL) mixture containing propane, butane, and heavier hydrocarbons separated during processing. Subcontractors working at gas plants or fractionation facilities will handle, transport, or maintain equipment tied to this product stream. Understanding its composition helps crews follow correct handling, storage, and safety protocols on site.

A corporate ownership arrangement where founders or executives hold shares with greater voting power than ordinary investors. For subcontractors, this means a client company's leadership can make major operational decisions without shareholder approval. Expect stable long-term contracts but limited outside pressure to change payment terms or procurement practices.

A confidential tender submission where subcontractors submit pricing without knowing competitors' rates. All bids are opened simultaneously by the hiring company. This process is common in public sector and large operator contracts across oil and gas and construction.

A monitoring technology that uses fibre-optic cables as continuous sensors along pipelines, wellbores, or structures. It detects temperature, strain, and acoustic changes across kilometres of cable in real time. Subcontractors may be hired to install, splice, or maintain these cable systems during construction or integrity projects.

A failure mode where metal components crack under the combined effect of tensile stress and corrosive environments. Subcontractors must inspect susceptible equipment — like pipelines, pressure vessels, and lifting gear — for early signs. Missed SCC (Stress-Corrosion Cracking) damage can trigger costly shutdowns, liability claims, or failed inspections.

A formal document issued under a master contract that authorises a specific scope of work, timeline, and budget. Subcontractors use task orders to mobilise crews and bill for individual job phases. Each task order typically carries its own number for invoicing and cost-tracking purposes.

Rig counts are the earliest signal of where field service work is heading. Learn how to read drilling activity trends, anticipate demand shifts, and position your crew before the phone stops ringing.

What Is an AFE in Oil and Gas and How Does It Affect Subcontractor Payments?

An AFE (Authorization for Expenditure) controls every dollar spent on an oilfield project. Learn how it affects your billing, change orders, and cash flow as a subcontractor.
