A 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.
Jackup
Related Terms
Wellsite Services
IndustryOn-location support work performed at an active drill site, including safety watch, equipment operation, and logistics. Subcontractors are typically mobilised on short notice and paid on a day-rate basis. Scope can shift quickly, so clear change-order processes are essential.
Appraisal Drilling
IndustryDrilling program that follows an initial discovery to confirm reservoir size and commercial viability. For subcontractors, it means short-term, high-intensity scopes between exploration and full development phases. Mobilisation windows can be tight and contract durations unpredictable.
Sequencing (construction)
IndustryThe planned order in which construction tasks must be completed before the next trade can begin work. Subcontractors depend on accurate sequencing to schedule crews and avoid costly downtime. Delays in one phase can push back your mobilisation and affect your invoicing schedule.
CSG (Casing)
IndustrySteel pipe installed in a wellbore to provide structural integrity and prevent contamination between different geological formations, requiring specialized installation and cementing services that subcontractors frequently provide during drilling operations.
OFS (Oilfield Field Services)
IndustryThe sector of companies and subcontractors that provide specialised labour, equipment, and technical services to oil and gas operators. This includes drilling, completions, maintenance, and production support work. Most field subcontractors operate within the OFS sector, working under Tier 1 service companies or directly for operators.
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.
