Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Gas Basin

A large underground region containing significant natural gas reserves, typically supporting multiple wells and facilities. For subcontractors, basins define key work corridors where long-term service demand is concentrated. Knowing active basins helps crews and companies target mobilisation and contract opportunities.

Related Terms

Upstream Tie-in

Industry

A connection point where new pipeline or equipment is integrated into an existing live system closer to the wellhead or source. For subcontractors, this work typically requires strict hot-work permits and precise scheduling around production shutdowns. Delays at tie-in points directly impact your crew's standby time and invoice milestones.

Frac Date

Industry

The scheduled date when hydraulic fracturing operations begin at a well site. For subcontractors, it drives crew mobilisation, equipment delivery, and invoice timing. Missing a frac date can result in penalties or loss of future work.

Multi-Zone Testing

Industry

A well evaluation process where multiple reservoir intervals are tested separately in a single wellbore operation. Subcontractors must coordinate pressure testing, fluid sampling, and equipment rigging across several zones. Scope changes between zones can affect crew hours, tool rentals, and invoicing significantly.

Reservoir Characterization

Industry

The process of mapping and analysing an underground reservoir's size, rock properties, and fluid content. Subcontractors use this data to understand scope for drilling, completions, and intervention work. It directly influences crew requirements, equipment specs, and contract duration.

Primary Term

Industry

The fixed initial period of a service contract during which either party is typically locked in. For subcontractors, it sets the guaranteed window to recover mobilisation costs and generate revenue. Work orders or rates often cannot be renegotiated until this period expires.

Midstream Infrastructure

Industry

The pipelines, compressor stations, and processing facilities that move and condition product between the wellhead and end markets. For subcontractors, it represents a major source of maintenance, construction, and inspection work. Contracts here often involve long project timelines and strict regulatory oversight.
