COR (Certificate of Recognition)

The handling, hauling, storage, and disposal of water used in hydraulic fracturing operations. Subcontractors often provide vacuum trucks, fluid hauling, and pit liner services across these stages. Proper documentation and disposal compliance are required to avoid liability on-site.

A formal document a subcontractor submits to a prime contractor or operator to express intent to bid on upcoming work. It is not a binding commitment, but helps secure a spot in the tender process. Common in pre-qualification stages for large oilfield or construction scopes.

A temporary staging base positioned close to active work sites, used to store equipment, house crews, and coordinate field operations. Subcontractors often mobilise from an FOL rather than returning to a main facility daily. This reduces travel time and keeps personnel and resources on standby near the job.

A group of 17 metallic minerals critical to manufacturing motors, sensors, and electronics used in oilfield and construction equipment. Supply chain disruptions can affect equipment availability and drive up costs for field service operators. Subcontractors should monitor REE-related procurement delays when planning equipment-intensive scopes.

A designated strip of land reserved for pipelines, power lines, or utility infrastructure. Subcontractors must obtain right-of-entry approvals before mobilising equipment or crews within these zones. Work inside corridors often triggers additional environmental and regulatory compliance requirements.

A scheduling system that calculates what materials are needed, in what quantities, and when. Subcontractors use it to avoid shortages or excess stock on job sites. It ties material orders directly to project timelines and scopes of work.

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.
