The 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.
Run-Life
Related Terms
Well Spacing
IndustryThe regulated distance between wellbores on a pad or lease area. Tighter spacing means more wells drilled closer together, increasing crew density and equipment demand. Subcontractors should anticipate compressed timelines and overlapping scopes when spacing is tight.
Sitework
IndustryPreparatory ground-level work completed before main construction begins, including grading, excavation, and utility rough-ins. Subcontractors are often scoped for sitework as a standalone package. Delays in sitework directly impact downstream trade access and schedule.
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.
SCOOP (South Central Oklahoma Oil Province)
IndustryA major oil and gas play in south-central Oklahoma targeting Woodford and Springer shale formations. Subcontractors working this basin should expect high-volume drilling and completions activity. It is a key area for securing long-term field service contracts.
Working Interest
IndustryAn ownership stake in an oil and gas lease that obligates the holder to pay a share of exploration and production costs. For subcontractors, knowing who holds working interest helps identify who is ultimately responsible for approving work orders and invoices. Operators typically hold majority working interest and are your primary point of contract.
Dual-Class Share Structure
IndustryA corporate ownership arrangement where founders or executives hold shares with greater voting power than ordinary investors. For subcontractors, this means a client company's leadership can make major operational decisions without shareholder approval. Expect stable long-term contracts but limited outside pressure to change payment terms or procurement practices.
