ERAS (Expedited Resource Addition Study)

A well evaluation process where multiple reservoir intervals are tested separately in a single wellbore operation. Subcontractors must coordinate pressure testing, fluid sampling, and equipment rigging across several zones. Scope changes between zones can affect crew hours, tool rentals, and invoicing significantly.

The equipment and techniques used to lift, secure, and move heavy loads on a job site. Subcontractors must ensure all rigging gear is certified and operators are ticketed. Improper rigging is a leading cause of serious incidents and contract liability.

A rock formation made of compacted sediment fragments — like sandstone or conglomerate — that holds oil or gas. Most drilling and completions work in Western Canada targets clastic reservoirs. Knowing the formation type helps crews anticipate ground conditions and equipment requirements.

A prepared surface site where one or more wellbores are drilled from a central location. Subcontractors often mobilise equipment and crew to serve multiple wells from a single pad. This reduces move-out costs and can extend your on-site contract duration.

Highly mineralised, hot saltwater extracted from underground geothermal reservoirs during energy production. Subcontractors handling it must follow strict corrosion control and PPE protocols. Disposal and handling are heavily regulated due to its chemical content.

A mobile conveyor system that extends in length and swings in an arc to stockpile bulk materials across a wide area. Commonly used on pipeline, mining, and civil construction sites for aggregate, gravel, or spoil management. Subcontractors operating this equipment typically require certified operators and may be responsible for setup, teardown, and repositioning.

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.
