Screening Circuit

A light liquid hydrocarbon that separates from natural gas during production and processing. Subcontractors handling condensate must follow strict hazmat protocols, as it is highly volatile and flammable. It is often measured and valued separately from crude oil on production sites.

A closed vessel used to process materials in discrete, timed cycles rather than continuously. Subcontractors may be called to inspect, clean, or maintain these units during scheduled shutdowns. Work is typically project-based, tied to turnaround or maintenance contracts.

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.

A chemical separation process used in oil sands and refining operations to isolate valuable substances from raw material. Field crews may support solvent handling, containment, and equipment maintenance during extraction cycles. Subcontractors working on these sites typically require specialised chemical safety training and PPE compliance.

A conditional agreement between a producer and gas buyer that must be satisfied before a project moves to full development. For subcontractors, it signals that major field mobilisation and long-term work commitments depend on this deal closing. Delays or failed negotiations can stall contracts, procurement, and crew deployment.

Loose, weakly bonded subsurface material — such as sand, gravel, or soft clay — that hasn't hardened into solid rock. These formations create unstable borehole conditions, increasing risk of collapse and equipment loss. Subcontractors drilling or excavating in these zones often face additional scope, specialised equipment requirements, and potential cost disputes.

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.
