Bcf/d (billion Cubic Feet Per Day)

A well design plan specifying the size, depth, and sequence of steel pipe (casing) run into a wellbore. For subcontractors, it dictates crew scheduling, equipment requirements, and service timing. Understanding it helps you anticipate your scope and mobilisation windows.

The process of pumping produced water or other fluid waste deep into underground formations for disposal. Subcontractors operating injection pumps or wellbore equipment must meet strict provincial and federal disposal regulations. Work often requires specialised well integrity certifications and detailed fluid volume reporting.

The process of moving existing underground or overhead utilities — such as gas lines, water mains, or electrical conduits — to accommodate new construction or pipeline work. Subcontractors are often hired specifically for this scope, which requires utility locates and coordination with municipal or utility owners. Delays in relocation can directly impact your crew's mobilisation schedule and project milestones.

Equipment or materials requiring extended procurement timelines, often months ahead of project start. Subcontractors must identify these early to avoid costly schedule delays. Late orders can stall mobilisation and trigger liquidated damages clauses.

A ground excavation method where holes are drilled into rock, then loaded with explosives and detonated. Subcontractors on these scopes typically require certified blasters and strict compliance with provincial explosives regulations. Expect tight sequencing with other trades and potential site shutdowns during blast windows.

A standard measure of a well site's or facility's total energy output, combining oil, gas, and NGLs into one comparable unit. Operators use BOE/D figures to size projects and determine crew and equipment requirements. Higher BOE/D rates typically signal larger scopes of work and longer service contracts for subcontractors.

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.
