Application of the Archimedes’s principle in the oil industry

Hydrometer Hydrometer is a device for measuring the density Hydrometers for oil ANT-1 and ANT-2 Ареометры для нефтепродуктов АНТ-1, АНТ-2 Применяется для определения показателя плотности нефти и нефтепродуктов (бензина, дизельного топлива и т.п.)

oil displacement Oil rises to the surface due to natural buoyant forces.

drilling The weight of the drill string will be strongly reduced by introducing a coefficient calculations buoyant forces.

Pumping unit Using the coefficient buoyancy force for calculating the load balance on the head of the pumping unit.
