Rig Count

The installation, calibration, and maintenance of measurement and control devices such as gauges, transmitters, and sensors. Subcontractors are often scoped specifically for instrumentation work, requiring certified trades and precise documentation. It is a common standalone discipline on large oil and gas and industrial construction projects.

A well drilled in an unproven or lightly tested area to determine whether hydrocarbons are present, often representing shorter-term, high-mobilisation contracts for subcontractors with less predictable follow-on work than development drilling programmes.

Refers to power generation or energy systems located on a client's side of the utility connection point. For subcontractors, this often means working on site-owned generators, solar arrays, or battery storage on industrial or remote worksites. Scopes here fall outside utility jurisdiction, affecting permitting and inspection requirements.

Compressed air networks that power pneumatic valves, controls, and instrumentation on oil and gas and industrial sites. Subcontractors must ensure supplied air meets strict dryness and purity standards before connecting equipment. Contaminated or wet instrument air can damage sensitive controls and trigger costly shutdowns.

The date when drilling begins on a new well. Marks the start of drilling operations.

Portable, stackable tank systems used on remote job sites to store potable, process, or wastewater. Subcontractors deploy them quickly without permanent infrastructure. Common on pipeline, camp, and frac support contracts.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements

When operators merge, get acquired, or sell assets, subcontractor agreements are caught in the middle. Learn how M&A activity affects your MSA, payment terms, vendor status, and what to do before, during, and after a deal closes.
