Telehandler

A subcontractor hired to perform one specific, clearly defined scope of work on a project. They operate independently from other trades and are not responsible for coordinating adjacent scopes. This structure limits liability exposure but also restricts opportunities to capture additional work on site.

The acceptable range of variation allowed in measurements, materials, or workmanship on a job site. Subcontractors must stay within these limits or face rework orders and cost penalties. Specs are set by the prime contractor or engineering drawings.

The network of pipelines, compressors, and processing facilities that collect hydrocarbons from wellheads and move them to processing or transmission points. For subcontractors, it represents a major source of construction, maintenance, and inspection work. Projects often run concurrently with drilling programmes, creating tight scheduling demands.

Underground storage facilities carved out of salt formations or rock, used to hold large volumes of natural gas, crude oil, or other hydrocarbons. Subcontractors handle construction, maintenance, inspection, and integrity testing at these sites, often needing confined-space and geotechnical certifications. Injection and withdrawal seasons create predictable maintenance windows, helping field service companies plan mobilisation.

A measure of a facility's annual production or processing capacity, expressed in millions of tonnes. Larger MTPA ratings typically signal longer project durations and higher subcontractor labour demand. Knowing a site's MTPA helps field service companies anticipate scope size and resource requirements.

A three-cylinder reciprocating pump used on drilling rigs to circulate drilling fluid down the wellbore. Subcontractors are often hired to operate, maintain, or repair these high-pressure units. Reliable pump performance is critical — downtime directly impacts rig schedules and your contract standing.

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.
