Industry Glossary Term

CCS (Carbon Capture and Storage)

A process that captures CO₂ emissions from industrial sources and injects them underground for permanent storage. For subcontractors, CCS projects create demand for pipeline welding, compression equipment installation, and wellsite services. Familiarity with emissions-related scopes can open access to a growing segment of energy infrastructure work.

Related Terms

Cementing

Industry

The process of pumping cement slurry into a wellbore to seal the casing and isolate formation zones. Subcontractors may be hired to provide cementing crews, pumping equipment, or bulk material handling. It is a critical well integrity step with strict regulatory and operator specifications.

Well Intervention

Industry

Any post-completion operation performed on a producing well to restore or improve output. Subcontractors are often mobilised for wireline, coiled tubing, or pump work during these campaigns. Scope can change quickly, so confirm work orders before committing crew and equipment.

Subsea Production System

Industry

A network of underwater equipment — including wellheads, manifolds, flowlines, and control systems — installed on the seabed to extract and transport oil or gas to a surface facility, representing a specialised scope of subsea installation, inspection, and maintenance work that subcontractors must hold specific certifications and equipment to perform. For field service companies, contracts in this space typically involve saturation diving support, remotely operated vehicle (ROV) operations, or subsea engineering services under strict offshore safety and quality regimes.

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.

Workover

Industry

Operations performed on an existing well to restore, maintain, or improve production. Includes activities like recompletions, artificial lift installation, and remedial cementing.

JV (Joint Venture)

Industry

A formal business arrangement where two or more companies partner to pursue a specific project or contract, which can affect subcontractors by changing who issues purchase orders, approves invoices, or holds liability on site. Field service companies should confirm early which JV partner is the contracting entity to avoid payment delays or scope disputes.
