Cementing
IndustryThe process of pumping cement slurry into a wellbore to seal the casing and isolate formation zones. Subcontractors may be hired to provide cementing crews, pumping equipment, or bulk material handling. It is a critical well integrity step with strict regulatory and operator specifications.
Combined Cycle
IndustryA power generation setup where waste heat from a gas turbine is reused to produce additional electricity via a steam turbine. Subcontractors working these facilities must be prepared for more complex systems and stricter safety protocols. Maintenance scopes are typically broader, covering both turbine types.
Field Ticket
IndustryA document created in the field that records work performed, equipment used, materials consumed, and time spent. Field tickets are the basis for invoicing and must typically be approved by the customer before payment.
Frontier Exploration
IndustryExploration activity conducted in remote, undeveloped, or previously unworked regions where subcontractors can expect longer mobilisation lead times, higher logistical costs, and limited access to local supply chains or support infrastructure.
Hot Shot
IndustryExpedited delivery service for equipment, parts, or materials to remote job sites. Often used for urgent oilfield deliveries.
Perforate
IndustryTo create precisely spaced holes or openings in oil well casing and cement at a target formation depth, allowing hydrocarbons to flow into the wellbore; subcontractors providing perforating services typically work under wireline or coiled tubing crews and must coordinate closely with the operator's completion schedule.
