Compression Station

Work performed on-site without removing equipment or materials from their installed position. Subcontractors are often mobilised specifically for in-situ repairs, inspections, or testing. Scope and billing should clearly reflect the fixed work location.

A structured engineering assessment identifying how equipment or piping could degrade, corrode, or fail. Subcontractors use DMR findings to scope inspection work and apply correct procedures. Ignoring DMR requirements can result in scope gaps, rework, or safety incidents.

Expedited delivery service for equipment, parts, or materials to remote job sites. Often used for urgent oilfield deliveries.

A continuous steel tube wound on a large reel, deployed downhole for well interventions, cleanouts, and stimulation work. Subcontractors often support CT operations as part of completions or well servicing scopes. Specialised CT crews and equipment typically require separate mobilisation planning and rate structures.

A company that provides specialized services to oil and gas operators, such as drilling, completions, workover, transportation, or maintenance. Also called oilfield services (OFS).

A method of planning services, maintenance, or contracts around the full lifespan of an asset or project phase. Subcontractors use it to align scopes of work, pricing, and resource deployment from mobilisation through decommissioning. This helps avoid scope gaps and supports longer-term service agreements.
