Modular Above-Ground Storage

A floating offshore structure anchored by a deep vertical cylinder, used in deepwater oil and gas production. Subcontractors access it by crew boat or helicopter for maintenance, inspection, and equipment services. Mobilisation costs and offshore scheduling are key considerations when bidding work on spars.

A well-site service that monitors drilling fluid returns to detect hydrocarbons and analyse formation data in real time. Subcontractors provide specialised technicians and instrumentation units for this work. It is commonly scoped as a standalone package within a drilling contract.

The process of pumping cement slurry into a wellbore to seal the casing and isolate formation zones. Subcontractors may be hired to provide cementing crews, pumping equipment, or bulk material handling. It is a critical well integrity step with strict regulatory and operator specifications.

The legal ownership of subsurface resources like oil, gas, and minerals on a property. Subcontractors work under operators who hold mineral rights, so understanding this ownership structure clarifies who controls site access and project authorisation. Disputes over mineral estates can halt work orders without warning.

The point when a project owner formally approves funding and commits to proceeding with a major project. For subcontractors, FID is the trigger that converts preliminary work into confirmed scopes and purchase orders. Mobilisation planning, crew hiring, and equipment sourcing typically begin after FID is announced.

A contract between an operator and a service company that establishes the general terms and conditions for all future work. Individual jobs are then executed under work orders or AFEs referencing the MSA.

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.

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.
