Large-diameter steel casings driven into the ground before main drilling begins to stabilise the wellbore and prevent surface collapse. Subcontractors involved in conductor installation, welding, or pile-driving work are typically mobilised in this early phase. Securing this scope early can anchor longer project commitments on a well site.

Related Terms
Laser Surface Ablation
IndustryA surface preparation method using focused laser energy to remove rust, coatings, or contaminants from metal. Subcontractors use it as a cleaner alternative to sandblasting on pipelines and structural steel. It reduces waste disposal costs and meets strict environmental site requirements.
Rig Utilization
IndustryThe percentage of time a rig is actively working versus sitting idle. For subcontractors, high rig utilisation means steady billable hours and predictable revenue. Low utilisation signals contract gaps that strain cash flow and crew retention.
Stockpoint
IndustryA designated location where materials, parts, or equipment are staged for quick deployment to active job sites. Subcontractors often draw inventory from a client's stockpoint rather than sourcing independently. Knowing stockpoint locations reduces mobilisation delays and simplifies cost tracking.
Design-Build
IndustryA project delivery method where one contractor handles both engineering design and construction under a single contract. As a subcontractor, you may be brought in mid-scope with limited drawing sets, requiring flexibility. Scope creep risk is higher since designs are still evolving while field work begins.
Phased Array Ut (phased Array Ultrasonic Testing)
IndustryAn advanced non-destructive testing method that uses multiple ultrasonic beams to inspect welds and materials for defects. It replaces traditional radiography on many pipeline and pressure vessel jobs. Subcontractors offering PAUT services often command higher rates and qualify for more specialised scopes.
NGL (Natural Gas Liquids)
IndustryHydrocarbons extracted from natural gas, including propane, butane, and condensate. NGL facilities and pipelines generate steady subcontract work in processing, instrumentation, and maintenance. Understanding NGL handling requirements helps crews meet site-specific safety and equipment standards.
