Program-measuring “PIK-AEI” complex for filtration experiments with current saturation X-ray control

The PIK-AEI complex is designed to carry out filtration experiments (oil displacement by water/gas, determination of relative phase permeabilities and the effectiveness of physicochemical methods of enhanced oil recovery) by stationary and non-stationary methods at reservoir conditions.

Core samples current saturation is estimated by the X-ray method, which also allows to record the dynamics of displacement front and end effects presence. The complex can be used to assess core samples density heterogeneity. The software allows conducting experiments in automatic mode.
