Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Dynamic Gas Blending

A real-time method of mixing gases at the wellsite to meet specific downhole pressure and composition requirements. Subcontractors operating blending equipment must hold current pressure vessel and gas handling certifications. Accurate blending logs are critical for compliance audits and client invoicing.

Related Terms

Shale Gas

Industry

Natural gas extracted from shale rock formations using hydraulic fracturing and horizontal drilling. For subcontractors, shale gas projects drive high demand for frac crews, equipment operators, and site services. Work is often concentrated in multi-well pad campaigns, creating steady but intense mobilisation cycles.

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.

Intervention Vessel

Industry

A specialised ship used to perform maintenance, repair, or remediation work on subsea wells and pipelines. Subcontractors are often mobilised to these vessels for ROV operations, well work, or equipment installation. Scheduling and access are tightly controlled by the operator.

RAP (Reclaimed Asphalt Pavement)

Industry

Milled or crushed material salvaged from existing asphalt surfaces during road removal or rehabilitation work. Subcontractors reuse RAP as base material or blend it into new asphalt mixes, reducing material costs. Proper handling and testing requirements may apply depending on project specs.

Helium Co-Production

Industry

The extraction of helium as a byproduct alongside natural gas from the same well or facility. Subcontractors may encounter specialised separation equipment and handling protocols on co-production sites. Scope of work can expand to include cryogenic systems and helium storage, affecting crew certifications and equipment requirements.

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.
