Extended-Reach Completions
IndustryCompletion work performed on wells drilled at extreme horizontal distances from the surface location, sometimes exceeding 3,000 metres laterally. Subcontractors face longer tool-run times, specialised equipment requirements, and increased logistics complexity. Mobilisation planning and crew scheduling must account for extended job durations compared to conventional completions.
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.
Development Sanction
IndustryThe formal approval by an operator or project owner to proceed with full-scale field development. For subcontractors, it signals that major contracts, mobilisation, and field work are imminent. It marks the point where scopes of work move from planning to active procurement.
Sanctioned Field
IndustryA field development that has received formal investment approval from the operator or project owner. For subcontractors, sanction signals that contracts, mobilisation, and work orders are imminent. It marks the transition from planning to active field execution.

IndustryA well-site service that monitors drilling fluid returns to detect hydrocarbons and analyse formation data in real time. Subcontractors provide specialised technicians and instrumentation units for this work. It is commonly scoped as a standalone package within a drilling contract.
Jackup
IndustryA mobile offshore drilling rig with retractable legs that jack down to the seabed, elevating the platform above water. Subcontractors mobilising to a jackup must account for offshore certification, marine logistics, and platform-specific access requirements.
