Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Undeveloped Inventory

Approved but undrilled well locations or untapped reserves an operator plans to develop in future phases. For subcontractors, it signals upcoming work pipelines and potential long-term contract opportunities. Tracking an operator's undeveloped inventory helps you anticipate mobilisation timelines and resource planning.

Related Terms

Curtailment

Industry

A reduction or suspension of oil, gas, or construction operations ordered by the operator or regulator. For subcontractors, curtailment often means standby, demobilisation, or reduced scope with little notice. Review your contract carefully for curtailment clauses that affect payment and mobilisation costs.

Run/repair/replace

Industry

A decision-making framework used to evaluate whether aging or damaged equipment should continue operating, be repaired, or be swapped out entirely. Subcontractors are often called in to assess assets and execute whichever option the client authorises. Understanding this process helps field crews scope work accurately and avoid scope creep on site.

Service Company

Industry

A company that provides specialized services to oil and gas operators, such as drilling, completions, workover, transportation, or maintenance. Also called oilfield services (OFS).

Subsea Architecture

Industry

The arrangement of underwater equipment — wellheads, flowlines, manifolds, and controls — that connects a seabed well to a surface facility. Subcontractors working in ROV operations, umbilical installation, or inspection services must understand this layout to execute scopes safely. Work packages are often structured around specific architecture components.

Valve Leak

Industry

A valve leak occurs when a valve fails to fully seal, allowing unintended fluid or gas flow. For subcontractors, it often triggers emergency callouts, inspection holds, or scope additions. Document all findings carefully to support change order billing.

Throughput Capacity

Industry

The maximum volume of work, materials, or product a crew or operation can process within a given timeframe. For subcontractors, it determines how many jobs or units can be delivered without bottlenecks. Knowing your throughput capacity helps with accurate bidding and resource planning.
