Leasehold

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 pipeline or flow line system that connects a new offshore wellhead or satellite field back to an existing production facility or platform, allowing operators to develop remote reserves without building standalone infrastructure. For subcontractors, tiebacks often involve specialised subsea installation, inspection, and maintenance scopes that require certified divers, ROV crews, or subsea engineering support.

A standardised measure combining oil, gas, and NGL output into a single daily production figure. Operators use it to size contracts and scope field service requirements. Higher BOEPD targets typically mean more crews, equipment, and sustained subcontractor workload.

Provincial agencies in Canada that provide workplace injury insurance. Contractors must maintain WCB coverage and good standing to work on most sites.

The replaceable filtering surfaces installed in vibratory shakers and separators on drilling and processing sites. Types include wire mesh, polyurethane, and rubber panels, each suited to different material grades. Subcontractors are often responsible for sourcing, swapping, and disposing of worn screen media during operations.

The upstream segment of the oil and gas industry covering the search for and extraction of hydrocarbons, representing the primary client base that hires field service subcontractors for drilling, completions, well servicing, and site construction work. Understanding whether a client operates in E&P helps subcontractors anticipate project cycles, budget timing, and the boom-and-bust demand patterns that directly affect contract volumes and payment 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.
