Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Below-Grade

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.

Related Terms

Horizontal Well

Industry

A well that is drilled vertically to a certain depth then curved to run horizontally through a target formation, requiring subcontractors to mobilise specialised equipment and crews for extended-reach drilling, completions, and stimulation work that typically involves more complex logistics and longer on-site durations than conventional vertical wells.

Mine Reclamation

Industry

The regulated process of restoring a mine site to an environmentally acceptable condition after operations cease. For subcontractors, it generates specialised scopes including grading, revegetation, and water treatment work. Reclamation projects often extend years beyond mine closure, providing longer-term contract opportunities.

Hookup

Industry

The phase where installed equipment and systems are connected to utilities, instrumentation, and process lines. For subcontractors, hookup work often follows construction and represents a distinct, billable scope. Crews must coordinate closely with commissioning teams to avoid delays.

LWD (Logging While Drilling)

Industry

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.

Waterway Crossing

Industry

A section of pipeline, conduit, or cable routed beneath or across a river, creek, or other body of water. Crossings typically use methods like horizontal directional drilling (HDD) or open-cut trenching. Subcontractors must meet strict environmental permits and inspection requirements before and after installation.

Preferred Vendor Status

Industry

A designation granted by an operator or prime contractor that puts your company on an approved list for recurring work. It typically means faster bid access, less vetting paperwork, and priority callouts. Earning it usually requires meeting set safety, insurance, and performance benchmarks.
