Infill Drilling

A lab process where gas is measured as it releases from rock core samples pulled during drilling. Subcontractors handling or transporting cores must follow strict protocols to preserve sample integrity. Mishandling can compromise data and trigger costly disputes with operators.

A pipeline integrity assessment using instrumented tools (smart pigs) run through the line to detect corrosion, cracks, or defects. Subcontractors are often mobilised for pig launching, data collection, and follow-up dig verification work. ILI campaigns can drive significant short-notice field service demand.

A thermal imaging inspection using IR (Infrared) cameras to detect heat anomalies in equipment, piping, or electrical systems. Subcontractors use these surveys to identify leaks, insulation failures, or overloaded components without shutting down operations. Clients often require certified IR thermographers, so confirm crew credentials before mobilising.

A prepared surface site where one or more wellbores are drilled from a central location. Subcontractors often mobilise equipment and crew to serve multiple wells from a single pad. This reduces move-out costs and can extend your on-site contract duration.

A document created in the field that records work performed, equipment used, materials consumed, and time spent. Field tickets are the basis for invoicing and must typically be approved by the customer before payment.

Specialty chemicals injected into wells and pipelines to control corrosion, scale, paraffin, and hydrates during oil and gas production. Subcontractors handle storage, injection system maintenance, and chemical dosing as part of production operations contracts. Proper handling certifications and spill containment protocols are typically required 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.
