Floating-Roof Storage Tank A large welded steel tank whose roof floats directly on the stored crude oil or product, eliminating the vapor space that drives evaporation losses and fire risk. 144 parts · 9 subsystems

Gas Compressor Station A gas-turbine-driven centrifugal compressor package for pipeline gas boosting, skid-mounted with process, lube/seal oil, control and safety systems. 570 parts · 9 subsystems

Gas Flare System An elevated combustion system that safely burns relief and blowdown gas from a process plant, keeping a continuously lit pilot ready for emergency releases. 89 parts · 8 subsystems

Glycol Dehydration Unit A packaged absorption system that strips water vapor from natural gas by contacting it with triethylene glycol, then regenerates the glycol by boiling the water off. 68 parts · 8 subsystems

Heater Treater A fired three-phase vessel that heats produced well fluid to break oil-water emulsions and separates it into sales oil, water, and gas. 44 parts · 7 subsystems

Hydraulic Fracturing Pump A skid-mounted high-pressure reciprocating plunger pump that injects fracturing fluid downhole during well stimulation. 145 parts · 8 subsystems

Indirect Line Heater A water-bath heater that warms high-pressure well gas flowing through an immersed coil, preventing hydrate freeze-ups downstream of pressure-reducing chokes. 72 parts · 7 subsystems

Iron Roughneck A hydraulic pipe-handling machine that spins and torques drill-pipe connections on the rig floor, replacing manual tongs. 104 parts · 7 subsystems

LNG Vaporizer (ORV) An open rack vaporizer that regasifies liquefied natural gas at -162 °C by running a falling film of seawater over finned aluminum heat-exchange panels. 603 parts · 7 subsystems

Oil Pumpjack A beam pumping unit (sucker-rod pump) that lifts crude from a shallow well. 141 parts · 12 subsystems

Oil-Gas Separator A pressure vessel that splits a wellstream into separate oil, gas and water phases by gravity and momentum. 87 parts · 9 subsystems

Subsea Wellhead Tree A subsea wellhead and vertical christmas tree controlling and routing hydrocarbon flow from a deepwater well to the flowline. 110 parts · 10 subsystems

Sucker-Rod (Beam) Pump Downhole The downhole pump of a beam-pumped well: a working barrel and two ball valves that lift crude on each rod stroke. 24 parts · 8 subsystems

Vapor Recovery Unit A skid-mounted compressor package that captures low-pressure hydrocarbon vapors from storage tanks and boosts them into the gas sales line instead of venting or flaring. 110 parts · 8 subsystems

Wellhead Christmas Tree The surface valve stack on a producing oil or gas well that controls and routes flow from the tubing to the flowline. 93 parts · 10 subsystems

Wellhead Control Panel A hydraulic-pneumatic cabinet that holds production wellhead valves open and shuts the well in automatically on abnormal pressure, fire, or operator command. 69 parts · 7 subsystems
