Bcfd (billion Cubic Feet Per Day)

A one-way valve or flap gate that allows water to drain freely but prevents backflow from rising tides or high water levels. Subcontractors working on coastal or waterfront sites must account for tide gate locations when planning drainage, excavation, or utility work. Ignoring these structures can cause flooding, schedule delays, and scope changes.

The horizontal distance drilled from the kickoff point to the end of a wellbore, typically measured in metres. Longer laterals mean more stages, more equipment, and extended crew time on location. Subcontractors should factor lateral length into job costing and resource planning.

A method of injecting a secondary fuel, such as natural gas or propane, into a diesel engine's air intake to supplement combustion. It reduces fuel costs and emissions on long-running field equipment. Subcontractors should verify fumigation setups meet emissions compliance requirements in their operating jurisdiction.

A multi-axle hydraulic platform vehicle used to move oversized modules, vessels, or heavy equipment on job sites. Subcontractors working heavy lifts or module installation scopes often coordinate directly with SPMT crews. Understanding load-out and transport sequencing is critical for scheduling your own work around these moves.

A control system combining electrical signals and hydraulic power to operate valves, actuators, and process equipment. Subcontractors working on commissioning or maintenance must be qualified to work on both electrical and hydraulic components. Specialised certification and intrinsically safe tools are typically required on-site.

The planned underground route a drill bit follows during horizontal directional drilling (HDD). Subcontractors use bore path data to plan equipment placement, crew positioning, and utility clearances. Deviations from the bore path can trigger rework costs and schedule delays.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements

When operators merge, get acquired, or sell assets, subcontractor agreements are caught in the middle. Learn how M&A activity affects your MSA, payment terms, vendor status, and what to do before, during, and after a deal closes.

How Rig Count Trends Affect Subcontractor Demand and What to Do About It

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.
