EOR (Enhanced Oil Recovery)

The mechanical excavation and removal of sediment, rock, or debris from riverbeds, harbours, or pipeline corridors using specialised equipment. Subcontractors are often engaged for site preparation, spoil disposal, and environmental compliance support. Scopes can range from small trenching jobs to large marine infrastructure projects.

A method where multiple wells are drilled from a single surface location, or pad. For subcontractors, this means sustained, back-to-back work cycles with minimal rig-up and tear-down time. Efficient mobilisation and crew scheduling are critical to maintaining productivity across the pad.

A written commitment from a client indicating they plan to award a subcontractor a contract. It allows work or mobilisation to begin before the formal contract is signed. LOIs are not always legally binding, so subcontractors should clarify payment obligations before proceeding.

Funds an operator spends on major assets like wells, pipelines, or facilities. High CAPEX cycles mean more subcontract opportunities for field crews and equipment providers. Low CAPEX periods often signal slower work volumes and tighter bid competition.

A drilling technique that collects formation data in real time as the bit advances. Subcontractors providing LWD services operate specialised downhole tools that transmit data to surface during the drill run. Mobilisation windows are tight, so crews and equipment must be ready on short notice.

A well used to pump fluids — such as water, CO2, or chemicals — into a subsurface formation for disposal or enhanced recovery. Subcontractors are commonly hired for drilling, wellbore servicing, and chemical injection work on these sites. Scope can include pump maintenance, pressure testing, and regulatory compliance support.

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.
