The process of mapping and analysing an underground reservoir's size, rock properties, and fluid content. Subcontractors use this data to understand scope for drilling, completions, and intervention work. It directly influences crew requirements, equipment specs, and contract duration.
Reservoir Characterization
Related Terms
JV (Joint Venture)
IndustryA 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.
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.
Look-Ahead Planning
IndustryA short-range scheduling method where subcontractors forecast work activities two to six weeks out. It identifies upcoming resource needs, crew requirements, and potential delays before they impact the schedule. Field teams use it to stay aligned with the prime contractor's project timeline.
Run-Life
IndustryThe expected operational lifespan of a downhole tool or piece of equipment before it requires servicing or replacement. For subcontractors, run-life directly affects rental billing cycles, maintenance scheduling, and equipment mobilisation costs. Shorter run-lives can erode margins if replacement or redress costs aren't priced into the contract.
Brownfield
IndustryAn existing facility—such as a producing well, pipeline, or plant—being modified, upgraded, or maintained rather than built from scratch. For subcontractors, brownfield work often means tighter workspaces, live equipment hazards, and stricter site access requirements. Scopes can change quickly due to unforeseen conditions uncovered during work.
Pjm (pennsylvania-New Jersey-Maryland) Interconnection Queue
IndustryA waiting list managed by PJM for new power generation and transmission projects seeking grid connection approval. Subcontractors use it to track upcoming infrastructure builds and time their bids accordingly. Long queue backlogs signal sustained field work demand in the PJM service territory.
