Related Terms

Grid-Tie

Industry

A system that connects on-site power generation to the utility grid. Subcontractors working on grid-tie installations must coordinate with utility companies and meet strict interconnection standards. Common on solar and wind projects in remote industrial or construction settings.

Tieback

Industry

A structural anchor or connection point used to secure equipment, pipelines, or wellheads back to an existing infrastructure system, commonly referenced in subcontractor scopes of work when connecting new installations to live or existing lines. Subcontractors should confirm tieback specifications and isolation procedures clearly in their contracts, as this work often involves elevated risk and may require additional certifications or permits.

Service Company

Industry

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

Hydraulic Fracturing

Industry

A well stimulation process where fluid is pumped at high pressure to crack subsurface rock and release oil or gas. Subcontractors are commonly engaged for pump operations, fluid handling, and equipment transport during frac campaigns. Work is often fast-paced and shift-intensive, with strict site access and safety requirements.

Production Shut-in

Industry

A temporary halt to oil or gas production at a well or facility, ordered by the operator. For subcontractors, this often means suspended work orders and delayed revenue until operations resume. Standby rates and demobilisation terms in your contract become critical during a shut-in.

Rig Count

Industry

The number of drilling rigs actively operating in a region. Published weekly by Baker Hughes, the rig count is a leading indicator of activity levels in the oil and gas industry.
