The above-water structure of an offshore platform, including processing equipment, living quarters, and wellheads.

Topside
Related Terms
CAPEX (Capital Expenditure)
IndustryFunds an operator spends on major assets like wells, pipelines, or facilities. High CAPEX cycles mean more subcontract opportunities for field crews and equipment providers. Low CAPEX periods often signal slower work volumes and tighter bid competition.
Carbon Dioxide Treater
IndustryA vessel or system used on oil and gas sites to remove CO2 (Carbon Dioxide) from produced gas or water streams. Subcontractors are often hired to install, service, and inspect these units. Proper handling requires H2S and pressure safety training.
Remote-Site Services
IndustryWork performed at isolated locations far from urban centres, such as camps, wellsites, or pipeline corridors. Subcontractors must self-manage logistics, including equipment, consumables, and crew rotations. Mobilisation costs and travel time significantly affect how contracts should be priced.
Injection Well
IndustryA well used to pump fluids — such as water, CO2, or chemicals — into a subsurface formation for disposal or enhanced recovery. Subcontractors are commonly hired for drilling, wellbore servicing, and chemical injection work on these sites. Scope can include pump maintenance, pressure testing, and regulatory compliance support.
Frac Flowback
IndustryThe phase after hydraulic fracturing when water, sand, and hydrocarbons flow back to surface from the wellbore. Subcontractors are often mobilised quickly to manage fluid handling, testing, and disposal. Flowback work can be short-duration but requires crews and equipment on standby.
Appraisal Well
IndustryA well drilled after a discovery to confirm the size and viability of a reservoir. For subcontractors, appraisal programmes signal short-term scopes before a full development decision is made. Mobilisation windows are often tight and contracts may be limited to single-well terms.
