A formal document issued by a client or general contractor authorising a subcontractor to perform a specific scope of work. It outlines the job details, location, timeline, and agreed rate. Subcontractors typically cannot invoice without a valid work order number.

Shaker Screens
IndustryMesh filters mounted on shale shakers that separate drill cuttings from drilling fluid on the rig. Subcontractors handling fluid management or solids control must track screen condition and swap them regularly. Damaged or plugged screens slow operations and can trigger downtime charges against your crew.
JIP (Joint-industry Project)
IndustryA cost-sharing initiative where multiple operators or companies fund research, technology development, or industry challenges together. For subcontractors, JIPs can open doors to new contracts, but procurement processes are often slow and heavily governed. Understanding which operators are involved helps you identify who holds the real budget authority.
Frac Campaign
IndustryA scheduled series of hydraulic fracturing operations across multiple wells or stages within a defined period, representing a concentrated burst of work that subcontractors must plan for with adequate crew, equipment, and supply chain capacity. For field service companies, winning a spot in a frac campaign can mean weeks of steady, high-volume work but also demands tight mobilisation timelines and the ability to scale up quickly.
Clastic Reservoir
IndustryA rock formation made of compacted sediment fragments — like sandstone or conglomerate — that holds oil or gas. Most drilling and completions work in Western Canada targets clastic reservoirs. Knowing the formation type helps crews anticipate ground conditions and equipment requirements.
Heavy Crude
IndustryOil with high viscosity and density, requiring specialised handling equipment and heat-assisted extraction methods. Field crews working heavy crude sites often face more demanding maintenance schedules and equipment wear. Subcontractors should factor in higher mobilisation and operational costs when tendering these projects.
HDD (Horizontal Directional Drilling)
IndustryA trenchless method used to install pipelines, conduits, or cables beneath obstacles like roads, rivers, or existing infrastructure. Subcontractors are typically engaged for the drill crew, mud mixing, and equipment operation. Scopes are highly specialised and often require certified operators and dedicated HDD spreads.
