Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Battery

A centralised surface facility where oil and gas from multiple wells is gathered, measured, and processed. Subcontractors frequently mobilise to battery sites for maintenance, instrumentation, and civil work. Knowing the battery layout helps crews plan access, logistics, and safe work zones.

Related Terms

Appraisal Drilling

Industry

Drilling program that follows an initial discovery to confirm reservoir size and commercial viability. For subcontractors, it means short-term, high-intensity scopes between exploration and full development phases. Mobilisation windows can be tight and contract durations unpredictable.

Takeaway Infrastructure

Industry

Pipelines, rail lines, and processing facilities that move product away from a well site or project area. Limited takeaway capacity can delay or shut down operations, directly affecting subcontractor schedules and utilisation. Always confirm takeaway status before committing crews and equipment to a project.

AFE (Authorization for Expenditure)

Industry

A budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.

Best-Value Scoring

Industry

A bid evaluation method where contractors are ranked on price plus non-price factors like safety record, experience, and equipment. Low bid alone does not win the work. Subcontractors must demonstrate overall capability, not just competitive rates.

CSG (Casing)

Industry

Steel pipe installed in a wellbore to provide structural integrity and prevent contamination between different geological formations, requiring specialized installation and cementing services that subcontractors frequently provide during drilling operations.

CRA (Corrosion Resistant Alloy)

Industry

Specialised metal used in pipelines and equipment exposed to corrosive fluids like H2S or CO2. Subcontractors must confirm material specs before welding or fabricating, as CRA requires certified procedures and qualified welders. Misidentifying CRA components can cause costly failures and compliance issues.
