Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Shut-In Production

A well or facility that has been temporarily halted from producing oil or gas. For subcontractors, shut-ins often mean suspended work orders and delayed invoicing. Confirm contract terms around standby rates before production stops.

Related Terms

Straddle Plant

Industry

A midstream processing facility installed along an existing pipeline to extract natural gas liquids like propane and butane. Subcontractors are frequently mobilised for construction, maintenance, and turnaround work at these sites. Work scopes often include compression, refrigeration, and fractionation system servicing.

BHA (Bottom Hole Assembly)

Industry

The collection of drilling tools and equipment at the bottom of the drill string, including the drill bit, drill collars, stabilizers, and downhole motors. For drilling subcontractors, BHA configuration directly impacts drilling performance, tool wear rates, and operational efficiency.

KPI (Key Performance Indicator)

Industry

A measurable target used to evaluate a subcontractor's performance on safety, productivity, or quality. Clients track KPIs to assess contract compliance and award future work. Common field KPIs include incident rates, on-time mobilisation, and equipment uptime.

MTPA (Million Tonnes Per Annum)

Industry

A measure of a facility's annual production or processing capacity, expressed in millions of tonnes. Larger MTPA ratings typically signal longer project durations and higher subcontractor labour demand. Knowing a site's MTPA helps field service companies anticipate scope size and resource requirements.

Long-Lead Items

Industry

Equipment or materials requiring extended procurement timelines, often months ahead of project start. Subcontractors must identify these early to avoid costly schedule delays. Late orders can stall mobilisation and trigger liquidated damages clauses.

Upstream

Industry

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