Industry Glossary Term

Trenchless

A method of installing or repairing underground pipelines and conduits without open excavation. Techniques include horizontal directional drilling (HDD) and pipe bursting. Subcontractors working trenchless scopes need specialised equipment and certified operators.

Related Terms

Near-Field Exploration

Industry

Exploration activity targeting new reserves close to existing producing infrastructure. For subcontractors, it often means faster mobilisation and shorter campaigns using established site access. Expect work scopes similar to existing nearby operations, with familiar equipment and logistics.

Below-Grade

Industry

Any work or structure located below the finished ground surface, such as buried pipelines, foundations, or conduits. Subcontractors must account for added costs like shoring, dewatering, and confined space compliance. Scope changes below-grade often trigger change orders due to unforeseen soil or utility conditions.

FEED (Front-end Engineering Design)

Industry

The detailed engineering phase before a project is sanctioned for full construction. For subcontractors, FEED signals that scopes, specs, and vendor lists are being finalised. Winning work during FEED often positions your company for contracts in the execution phase.

Task Order

Industry

A formal document issued under a master contract that authorises a specific scope of work, timeline, and budget. Subcontractors use task orders to mobilise crews and bill for individual job phases. Each task order typically carries its own number for invoicing and cost-tracking purposes.

Multi-Well Pad

Industry

A single surface location where multiple wells are drilled and completed in sequence. For subcontractors, this means extended site presence, higher mobilisation value, and repeated service cycles from one location. Scheduling and crew continuity are critical to securing ongoing work across the pad.

Legacy Site

Industry

An older facility or work location operating on outdated infrastructure, systems, or equipment. Subcontractors often face non-standard conditions, ageing assets, and extra compliance requirements on these sites. Mobilisation and scoping costs can be higher due to undocumented or deteriorated site conditions.
