Near-Field Exploration

A moored vessel used solely to store crude oil or LNG offshore, without production capabilities. Subcontractors are engaged for inspection, maintenance, and marine support work aboard these assets. Mobilisation logistics and offshore safety certifications are typically required before access is granted.

A rock formation believed to contain oil or gas, targeted for drilling or evaluation. Subcontractors are often mobilised to support exploration work within these zones. Scope and duration of field service contracts may depend on how many prospective intervals a well will test.

A formal arrangement where a general contractor or operator pre-qualifies subcontractors for priority work access. Approved vendors are typically offered first right of refusal on new projects. Getting listed can mean steadier work volume but often requires meeting strict safety, insurance, and pricing criteria.

Refers to oil reservoirs located beneath thick layers of underground salt, typically in deepwater offshore basins. For subcontractors, pre-salt projects involve specialised equipment, extended mobilisation timelines, and higher operational complexity. Expect longer contract cycles and stricter certification requirements from operators.

A series of controlled flow and pressure measurements performed on a newly drilled or existing well to evaluate its production potential and reservoir characteristics; for subcontractors, this work often involves deploying and operating specialised equipment such as separators, flowback units, and data acquisition systems under tightly scheduled, high-priority conditions.

A long-term contract where a buyer commits to purchasing a set volume of product from a producer. For subcontractors, these agreements signal stable, ongoing site activity and sustained demand for field services. They often underpin project financing, making worksites more financially secure for service providers.

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.
