Self-Build

The phase of oil and gas well development after drilling is finished, encompassing the work required to prepare a well for production — including perforating, fracturing, and installing wellhead equipment. For subcontractors, completions represent a concentrated burst of high-demand field work where specialised crews, equipment, and services are mobilised under tight timelines.

A cost-sharing initiative where multiple operators or companies fund research, technology development, or industry challenges together. For subcontractors, JIPs can open doors to new contracts, but procurement processes are often slow and heavily governed. Understanding which operators are involved helps you identify who holds the real budget authority.

A well drilled after a discovery to confirm the size and viability of a reservoir. For subcontractors, appraisal programmes signal short-term scopes before a full development decision is made. Mobilisation windows are often tight and contracts may be limited to single-well terms.

A scheduled period when a marine vessel is removed from service for inspection, repairs, or maintenance. For subcontractors, dry dock signals a concentrated burst of work — hull cleaning, mechanical repairs, and compliance checks. Scope can be substantial, so resource planning and contract clarity are critical.

The open entrance and exit points of a tunnel where underground meets surface operations. For subcontractors, portals are critical mobilisation zones for equipment, crews, and material staging. Access, congestion, and safety controls at portals directly affect your crew's productivity and schedule.

Preparatory ground-level work completed before main construction begins, including grading, excavation, and utility rough-ins. Subcontractors are often scoped for sitework as a standalone package. Delays in sitework directly impact downstream trade access and schedule.

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.
