Industry Glossary Term

Downhole Tools

Specialised equipment run into a wellbore to perform drilling, measurement, or completion tasks. For subcontractors, these tools often require certified handling, transport, and make-up procedures. Improper use can trigger costly liability or contract disputes.

Related Terms

DRA (Drag-reducing Agent)

Industry

A chemical additive injected into pipelines to reduce turbulence and increase flow rates without adding compression. Subcontractors handling pipeline operations or chemical injection work may be scoped to install, maintain, or monitor DRA injection skids. Understanding DRA systems helps crews execute chemical handling tasks safely and meet operator flow assurance targets.

Gas Sales Precedent Agreement

Industry

A conditional agreement between a producer and gas buyer that must be satisfied before a project moves to full development. For subcontractors, it signals that major field mobilisation and long-term work commitments depend on this deal closing. Delays or failed negotiations can stall contracts, procurement, and crew deployment.

Capital Discipline

Industry

When operators strictly control spending and delay or cancel projects to protect their balance sheets. For subcontractors, this means fewer awarded contracts, reduced scopes, and tighter bid competition. Expect slower mobilisation timelines and more rigorous cost justification from clients.

Hydroblasting

Industry

High-pressure water jetting used to clean, strip, or cut surfaces on industrial equipment and structures. Subcontractors typically require specialised certification and equipment to bid this scope. It is common in tank cleaning, pipeline maintenance, and surface prep work.

Tie-In

Industry

A tie-in is the physical connection of new pipeline or equipment to an existing operational system. For subcontractors, tie-in work often requires strict scheduling around shutdowns and may involve additional safety and permitting requirements. Scope changes during tie-ins can affect billing, so clear change-order terms are essential.

In-Situ Repair

Industry

Fixing or restoring equipment and structures at their installed location, without removal or shutdown. Subcontractors performing in-situ work often command premium rates due to specialised techniques and confined-space conditions. Scope clarity upfront is critical, as discovered defects can significantly expand the job.
