GOR (Gas-oil Ratio)

A contract where the subcontractor delivers a fully completed scope for a fixed price, assuming all cost and schedule risk. The client pays only upon project completion, not for time or materials spent. This model demands tight cost control, as overruns come directly out of your margin.

Underground storage facilities, typically salt caverns, used to store hydrocarbons like natural gas or crude oil. Subcontractors may be engaged for cavern construction, well drilling, piping, and surface facility work. Projects often involve specialised equipment and compressed timelines tied to storage demand cycles.

A pressure integrity test where pipelines, vessels, or equipment are filled with water and pressurised to detect leaks or weaknesses. Subcontractors are often hired to perform or witness these tests before commissioning. Proper documentation is critical, as clients and regulators require certified test records.

A timeline that outlines when specific tools, equipment, or crews are deployed downhole or on-site during an operation, dictating when a subcontractor's services are required and for how long. For field service companies, the run schedule directly determines mobilisation timing, crew rotations, and invoiceable hours on location.

A prefabricated, relocatable accommodation facility used to house workers on remote oil & gas or construction sites. Units are shipped and assembled on-site, then dismantled when the project ends. Subcontractors may bill camp costs separately or include them in their overall project pricing.

A secondary recovery method where water is injected into a reservoir to push remaining oil toward producing wells. Subcontractors support waterflood projects through injection well services, pump maintenance, and water handling infrastructure. Work scope can be long-term, offering stable recurring contracts.

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.
