STACK (Sooner Trend Anadarko Basin Canadian and Kingfisher)

2P (Proved Plus Probable) Reserves represent the total oil or gas a client is reasonably confident exists and can extract. Operators use 2P figures to justify long-term capital spending and multi-year field development plans. Higher 2P reserves often signal sustained work programmes and stronger subcontractor demand.

A facility that pressurises natural gas to move it through pipelines. Subcontractors are commonly hired for maintenance, instrumentation, and turnaround work at these sites. They often require site-specific safety orientations and H2S certifications.

A company hired to deliver a project from design through build, acting as the main contractor above subcontractors. As a subcontractor, your client and contract holder is typically the EPC, not the asset owner. They control scope, scheduling, and invoice approval on site.

A vertical guide structure on a pile-driving or drilling rig that keeps the drill string or pile aligned during penetration. Subcontractors working near this equipment must follow strict exclusion zone protocols. It is also called a mast or leads on some rigs.

A statistical method used to predict the likelihood of rare but severe events, such as equipment failures or extreme weather. Field service contractors use EVA to assess project risk and plan contingency resources. It helps justify standby equipment costs and mobilisation buffers in contract negotiations.

A project built from scratch on a previously undeveloped site, with no existing infrastructure. For subcontractors, this means longer mobilisation timelines and higher early-stage labour demand. Expect more scope changes and stronger opportunities for long-term contract 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.
