Limited Notice To Proceed

A project delivery method where design and construction phases overlap, with the owner and contractor collaborating before scope is fully defined. Subcontractors are often brought on early, meaning scope, pricing, and schedules can shift as design matures. Contracts may be cost-reimbursable at first, then convert to fixed-price once scope is confirmed.

A PRV (Pressure-Regulating Valve) automatically maintains downstream pressure at a set level within piping or process systems. Subcontractors installing or servicing PRVs must follow manufacturer specs and site pressure ratings precisely. Improper calibration can trigger shutdowns, client penalties, or serious safety incidents.

Structures used to drill for oil and gas, either onshore or offshore. For subcontractors, they are primary worksites where specialised services like maintenance, inspection, and equipment supply are contracted. Mobilisation requirements, safety certifications, and site access protocols vary significantly between rig types.

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.

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.

The process of improving drilling speed, efficiency, and cost performance on a well. Subcontractors may be asked to adjust crew rotations, equipment deployment, or service timing to support optimisation targets. Faster drilling cycles can shorten contract durations, affecting your crew planning and invoicing schedules.

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.
