Two parallel horizontal wells — one injector, one producer — used together in SAGD (Steam Assisted Gravity Drainage) operations. Subcontractors are typically mobilised to service both wells as a single scope. Expect coordinated drilling, completions, and maintenance schedules across both wellbores.

Building projects covering commercial, industrial, and institutional structures rather than homes. For subcontractors, this includes work on warehouses, refineries, offices, and infrastructure. These projects often involve larger contracts, stricter compliance requirements, and longer payment cycles.

A formal process that prolongs the operational life of ageing assets beyond their original design lifespan. For subcontractors, it often means increased inspection, repair, and maintenance scopes. Expect stricter compliance requirements and potential for longer-term service contracts.

A delivery model where one firm handles both project management and general contracting. For subcontractors, this means a single point of contact manages your scope, schedule, and contract. Expect tighter coordination requirements and change order oversight from the CM/GC.

A power generation setup where waste heat from a gas turbine is reused to produce additional electricity via a steam turbine. Subcontractors working these facilities must be prepared for more complex systems and stricter safety protocols. Maintenance scopes are typically broader, covering both turbine types.

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.

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.
