Industry Glossary Term

Lease Sale

A government auction where energy companies bid for the right to explore and develop specific land or offshore blocks. Winning bids signal upcoming exploration activity, which often leads to new work opportunities for field service subcontractors. Tracking lease sales helps companies anticipate demand and position crews and equipment accordingly.

Related Terms

Coiled Tubing

Industry

A continuous steel tube wound on a large reel, deployed downhole for well interventions, cleanouts, and stimulation work. Subcontractors often support CT operations as part of completions or well servicing scopes. Specialised CT crews and equipment typically require separate mobilisation planning and rate structures.

Appraisal Well

Industry

A well drilled after a discovery to confirm the size and viability of a reservoir. For subcontractors, appraisal programmes signal short-term scopes before a full development decision is made. Mobilisation windows are often tight and contracts may be limited to single-well terms.

IMR (Inspection, Maintenance, and Repair)

Industry

A category of ongoing field service work covering routine inspections, preventive maintenance, and corrective repairs on infrastructure or equipment, often awarded to subcontractors through standing agreements or blanket contracts. For field service companies, IMR scopes provide a reliable stream of recurring work but typically require crews to mobilise quickly and hold multiple trade certifications to meet operator requirements.

Long-Lead Procurement

Industry

The advance ordering of materials or equipment with lengthy manufacturing or delivery timelines. For subcontractors, delays in these items often push back mobilisation dates and affect project cash flow. Always confirm long-lead delivery schedules before locking in your crew start dates.

BHA (Bottom Hole Assembly)

Industry

The collection of drilling tools and equipment at the bottom of the drill string, including the drill bit, drill collars, stabilizers, and downhole motors. For drilling subcontractors, BHA configuration directly impacts drilling performance, tool wear rates, and operational efficiency.

Reactivation

Industry

The process of bringing a dormant well, pipeline, or piece of equipment back into active service, often requiring subcontractors to mobilise crews, conduct inspections, and complete compliance checks before full operations can resume. For field service companies, reactivation work can represent a significant surge in contract opportunities, particularly during periods of rising commodity prices.
