Where Elevated Tanks Work -- and Why Height Matters
The elevated storage tank solves a specific operational problem: how to load a road tanker with crude oil or produced water without a pump, without electrical power, and without permanent infrastructure. The answer is height -- raise the tank 2.5-4.5 metres, and the static liquid head plus any available line pressure is enough to drive gravity loading into a tanker positioned beneath the outlet nozzle.
Wellsite Crude Oil Storage & Gravity Loading
At producing wellsites without pipeline connections, crude oil is stored in an elevated tank and periodically loaded into road tankers for transport. The elevated tank provides the gravity head for tanker loading without a pump. For the operator, this eliminates a pump from the wellsite equipment list: no pump to maintain, no motor to power, no seal to replace.
Chemical and Utility Fluid Storage
Elevated tanks in smaller sizes (5-20 m³) are used for chemical storage -- demulsifier, scale inhibitor, methanol -- at wellsites and gathering stations. The elevation allows gravity dispensing into chemical injection skid day tanks. Constructed with appropriate internal coating or lining and supplied with a lockable outlet valve.
Produced Water Storage and Removal
Produced water separated from crude oil must be stored before disposal. An elevated tank allows gravity transfer to the disposal truck or gravity injection directly into a disposal well. For high-salinity or H₂S-bearing produced water, internal glass-flake epoxy lining is utilized to account for the corrosive nature of the fluid.
Component of Integrated Wellsite Systems
Elevated tanks are a core component of LINSON OIL's multi-function wellsite storage collector. Operators who have already purchased a multi-function collector and need additional storage capacity can add a standalone elevated tank connected to the collector's existing outlet piping.

Design Considerations That Matter for Field Reliability.
01 Tank Vessel Design
The tank vessel is a horizontal or vertical cylindrical vessel designed for atmospheric or low-pressure service. The standard 40m³ unit uses a horizontal cylindrical vessel -- providing a low centre of gravity, stable structural behaviour, and a short overall unit height. The vessel shell is Q235B or Q345R carbon steel, with wall thickness calculated per GB 50341. For crude oil service, the internal surface is cleaned and coated with solvent-resistant epoxy. For corrosive produced water, an internal glass-flake epoxy lining is standard.
02 Structural Frame Design
The structural steel frame -- four or six legs with cross-bracing -- carries the full weight of the tank plus the maximum liquid load plus the wind load at the installation site. For the standard 40m³ unit, the frame is designed for a specific wind speed zone. Base plates are sized for the bearing capacity of the standard concrete pad foundation; LINSON OIL provides the pad design specification with each unit so the site team can prepare the correct foundation before tank delivery.
03 Elevation and Loading Head
The standard unit elevation (distance from ground to tank base) is 2.5-3.5 m. At 2.5 m elevation with a full tank of crude oil (SG ≈ 0.85), the static head at the ground-level loading outlet is approximately 21 kPa (0.21 bar) -- sufficient for gravity loading. For higher-viscosity crudes or longer loading hose runs, a higher elevation may be specified. LINSON OIL calculates the required elevation based on the crude viscosity, loading hose length, and required loading rate.
04 Breather Valve Sizing
The breather valve (pressure-vacuum relief valve) is sized per API 2000 for the maximum liquid inflow rate and the maximum liquid outflow rate (during tanker loading). Undersized breather valves cause vacuum collapse of the tank roof during rapid drainage -- one of the most common modes of tank damage in field service. LINSON OIL sizes the breather valve as part of the standard design, not as an afterthought.
05 Optional Electric Heating
For high-pour-point crude oils, an electric immersion heater maintains the tank temperature above the pour point during storage. The heating element is sized for the thermal load: heating the daily crude inflow and compensating for heat loss to the design ambient minimum temperature. LINSON OIL always recommends insulation for heated crude storage in cold climates to significantly reduce the heating element size.
