Interconnection

A form of metal damage where hydrogen causes stacking cracks to form perpendicular to applied stress in steel pipe and pressure vessels. Common in sour service environments like H2S-containing oil and gas systems. Subcontractors doing inspection or repair work must flag suspected SOHIC immediately, as it signals serious structural failure risk.

Agreed reductions in oil production by member nations, typically OPEC (Organization of the Petroleum Exporting Countries) members, to stabilise prices. For subcontractors, these cuts often trigger project deferrals, reduced scope, and slower mobilisation schedules. Budget freezes from operators frequently follow, directly impacting field service award timelines.

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.

Crushed stone, gravel, and sand used as base materials in construction and oil and gas site preparation. Subcontractors sourcing or hauling aggregates must account for material costs, transport, and site access conditions. Pricing and availability vary significantly by region and project remoteness.

A lump-sum payment made by an operator to secure rights to a lease block, separate from royalties. For subcontractors, a large bonus bid signals operator commitment and can indicate upcoming project activity in that area.

A centralised facility or region where hydrogen is produced, stored, and distributed at scale. For subcontractors, these projects generate long-term work in pipefitting, instrumentation, and equipment installation. Expect strict safety certifications and specialised trade requirements on site.

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.
