The process of mapping and analysing an underground reservoir's size, rock properties, and fluid content. Subcontractors use this data to understand scope for drilling, completions, and intervention work. It directly influences crew requirements, equipment specs, and contract duration.
Industry Glossary Term
Reservoir Characterization
Related Terms
Oil Rigs
IndustryStructures used to drill for oil and gas, either onshore or offshore. For subcontractors, they are primary worksites where specialised services like maintenance, inspection, and equipment supply are contracted. Mobilisation requirements, safety certifications, and site access protocols vary significantly between rig types.
LNG (Liquefied Natural Gas)
IndustryNatural gas cooled to -162°C to become liquid for easier transport and storage, creating specialized work opportunities for subcontractors in cryogenic equipment maintenance, pipeline construction, and terminal facilities that require specific safety certifications and cold-weather expertise.
LWD (Logging While Drilling)
IndustryA drilling technique that collects formation data in real time as the bit advances. Subcontractors providing LWD services operate specialised downhole tools that transmit data to surface during the drill run. Mobilisation windows are tight, so crews and equipment must be ready on short notice.
Grid Hardening
IndustryUpgrades to electrical infrastructure that improve resilience against outages, extreme weather, and physical damage. For subcontractors, it drives demand for line work, equipment installation, and civil construction crews. Contracts often involve tight timelines and utility compliance requirements.
Vam Connections
IndustryPremium threaded pipe connections used in oil and gas drilling and completion operations. Subcontractors handling, installing, or inspecting VAM connections must follow strict torque specs and handling procedures. Improper makeup can result in costly downhole failures and liability exposure.
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.
