Pylon

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 cone-shaped separation device that removes solids or liquids from drilling fluids using centrifugal force. Subcontractors service and maintain these units on drilling rigs and fluid processing systems. Proper handling requires familiarity with high-pressure fluid systems and waste disposal regulations.

The ongoing process of ensuring pipelines remain safe, structurally sound, and compliant with regulatory standards. Subcontractors are frequently hired for inspection, maintenance, and repair work tied to integrity programmes. Scopes can include ILI (Inline Inspection), coating repairs, hydrotesting, and fitness-for-service assessments.

CBM (Coal Bed Methane) is natural gas extracted from coal seams rather than conventional reservoirs. Field crews typically handle dewatering operations, pipeline tie-ins, and wellsite maintenance on CBM projects. Work is often spread across large numbers of shallow, closely spaced wells requiring frequent travel between sites.

A group of storage tanks at a well site that collect and separate oil, gas, and water from production. Subcontractors are frequently mobilised here for gauging, maintenance, and fluid handling work. It is a common recurring service location on producing leases.

Equipment or materials requiring extended procurement timelines, often months ahead of project start. Subcontractors must identify these early to avoid costly schedule delays. Late orders can stall mobilisation and trigger liquidated damages clauses.

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.
