Daily oil & gas and construction news for subcontractors

Industry Glossary Term

Oil Rigs

Structures used to drill for oil and gas, either onshore or offshore. For subcontractors, they are primary worksites where specialised services like maintenance, inspection, and equipment supply are contracted. Mobilisation requirements, safety certifications, and site access protocols vary significantly between rig types.

Related Terms

Utility Boring

Industry

A trenchless drilling method used to install underground conduits, pipelines, or cables beneath roads, rivers, or structures. Subcontractors are often hired for utility boring to minimise surface disruption on job sites. Scopes typically include equipment mobilisation, bore path planning, and spoil disposal.

OSHA

Industry

Occupational Safety and Health Administration. The US federal agency responsible for workplace safety regulations. Compliance with OSHA standards is required for contractors working in the United States.

Directional Drilling

Industry

A drilling technique used to steer a wellbore along a non-vertical path to reach a target zone. Subcontractors supporting these operations often require specialised tooling, MWD (Measurement While Drilling) equipment, and certified directional hands. Scopes can shift quickly, so flexible crew and equipment mobilisation is essential.

Waterflood

Industry

A secondary recovery method where water is injected into a reservoir to push remaining oil toward producing wells. Subcontractors support waterflood projects through injection well services, pump maintenance, and water handling infrastructure. Work scope can be long-term, offering stable recurring contracts.

Mobilization/Demobilization

Industry

The process of moving equipment and personnel to a job site (mobilization) and returning them afterward (demobilization). Often billed as separate line items.

Upstream

Industry

The segment of the oil and gas industry involved in exploration and production (E&P). Includes drilling, completions, and well operations.
