Mmcf/d (million Cubic Feet Per Day)

A large self-propelled machine that cuts, crushes, and loads material in a single pass without blasting. Subcontractors operating surface miners must hold specialised equipment certifications and follow strict site safety protocols. Common in oil sands and open-pit construction projects across Western Canada.

The grid operator managing Texas's independent power network, separate from national grids. Subcontractors working Texas energy projects must understand ERCOT rules govern power availability and outages. Grid instability events like Winter Storm Uri directly impact field site operations and project timelines.

Systems that use compressed air or gas to power tools, actuators, and control valves on job sites. Subcontractors working with pneumatic equipment must ensure proper pressure ratings and fittings are maintained. Common in instrumentation, pipeline, and heavy construction scopes.

The seasonal period when melting snow and frost causes ground conditions to soften, restricting heavy equipment access to remote sites. Municipalities impose road bans limiting load weights, delaying material hauls and crew mobilisation. Subcontractors should plan for project slowdowns and reduced billable hours during this window.

Refers to oil reservoirs located beneath thick layers of underground salt, typically in deepwater offshore basins. For subcontractors, pre-salt projects involve specialised equipment, extended mobilisation timelines, and higher operational complexity. Expect longer contract cycles and stricter certification requirements from operators.

A system used to boost production from oil wells that lack sufficient natural pressure to bring fluids to surface. Common methods include rod pumps, ESPs (Electric Submersible Pumps), and gas lift. Subcontractors are often mobilised to install, service, or troubleshoot these systems throughout a well's producing life.

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.
