Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

MWD (Measurement While Drilling)

A real-time data acquisition process used during directional drilling that transmits downhole measurements — such as wellbore trajectory, formation data, and tool orientation — to surface crews without interrupting operations. For subcontractors, MWD services represent a specialised scope of work requiring certified technicians and dedicated equipment, often billed as a separate line item on drilling contracts.

Related Terms

Spud Date

Industry

The date when drilling begins on a new well. Marks the start of drilling operations.

Chokepoint

Industry

A stage in a project where workflow bottlenecks, delaying downstream tasks and crew productivity. For subcontractors, chokepoints often occur at inspection holds, permit approvals, or material deliveries. Identifying them early helps protect schedule and avoid costly standby time.

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.

Direct-Air Capture

Industry

DAC (Direct-Air Capture) is a technology that pulls CO₂ directly from the atmosphere using specialised equipment. Subcontractors may support DAC facility construction, maintenance, or mechanical services as energy clients expand carbon removal projects. It is an emerging work sector tied to federal clean-technology incentives in Canada.

ERP (Enterprise Resource Planning)

Industry

Software that centralises a subcontractor's core business functions, including payroll, invoicing, procurement, and scheduling. It replaces disconnected spreadsheets and paper systems with a single source of operational data. Larger GCs and operators may require subcontractors to integrate with their ERP for work orders and payment processing.

Abandonment

Industry

The regulated process of permanently closing a well or facility at end-of-life. Subcontractors are often hired for plugging, reclamation, and site cleanup scopes. Abandonment projects can be steady work but require strict compliance with provincial regulations.
