The Flow Rig Laboratory

The Flow Rig Laboratory (in Norwegian; Strømningslaben) provides experiments on water flood, liquid-liquid and liquid-gas relative permeability in situ reservoir conditions in core samples. Since 2012, the The Flow Rig Laboratory has served as a research facility for PhD research fellows and scientists at the Dept. of Geosciences, UiO. The lab is also open for routine measurements to industry clients and non-UiO organisations.

About the Flow Rig Lab (Strømningslaben)

To examine the flow of fluid in porous rock in The Flow Rig Laboratory, the main attention is given to the evaluation of some specific rock properties, such as permeability and porosity.

In achieve this Core Flooding is used to determine rock permeability and test the interaction of the core sample in various fluids. The core sample from the oil reservoir is placed in a rock core holder with specific dimensions. Once the core installed the outer surface is pressurised to simulate the same pressure as it was in the oil reservoir.

A test fluid is then pumped through the core in the flow rig, and the flow rates and pressure drops across the core are measured. From this data, the resistance to flow is evaluated. All these results are generally used as basic data for any reservoir engineering study of a conventional reservoir.

The laboratory can by appointment be used in research activities or/and assist students at the Department of Geosciences.
