Appraisal Well

A project requiring multiple specialised trades — such as welders, pipefitters, and electricians — deployed in sequence or simultaneously. Subcontractors must coordinate closely to avoid schedule conflicts and delays. Winning work on these projects often requires demonstrating multi-discipline capacity to the prime contractor.

A drilling programme where rigs operate continuously at accelerated rates to maximise footage drilled in minimal time. Subcontractors face compressed mobilisation windows, higher equipment wear, and rapid crew rotation demands. Billing cycles and material supply chains must keep pace with the accelerated schedule.

An underground facility built to permanently store nuclear or hazardous waste deep in stable rock formations. For subcontractors, DGR projects involve highly regulated excavation, tunnelling, and civil work with strict compliance requirements. Expect extensive worker certification, site access controls, and long project timelines.

A non-destructive digging method that uses high-pressure water or air to break up soil, then suctions the spoil into a debris tank. Commonly used to safely expose buried utilities before mechanical excavation begins. Subcontractors are often required to perform vacuum excavation in congested pipeline corridors or urban job sites.

Software platform used to coordinate schedules, documents, and workflows on construction projects. Subcontractors use it to submit RFIs, track approvals, and log daily field activity. Access is typically granted by the general contractor or owner.

A large underground region containing significant natural gas reserves, typically supporting multiple wells and facilities. For subcontractors, basins define key work corridors where long-term service demand is concentrated. Knowing active basins helps crews and companies target mobilisation and contract opportunities.

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.
