PIK-OFP/EP Automated Software-Controlled Measurement System

The apparatus is intended for the study of formation reservoir properties of core samples in reservoir conditions. The hydraulic system of the apparatus creates a two-phase flow (liquid/liquid) through core samples. The apparatus is controlled and monitored from a PC.

Capabilities

The PIK-OFP/EP apparatus can determine the following parameters of core:

Two-phase relative permeability values of core for “liquid/liquid” flow components according to OST 39-235-89 standard;
Residual oil saturation;
Effective porosity in reservoir conditions;
Effective porosity change depending on variation of reservoir conditions;
Liquid permeability coefficient;
Electric resistance.

Advantages

To control parameters of core, a full hydraulic isolation of the hydraulic layout is used, which makes it possible to use both oil and water to apply rock pressure, thus making the design simpler and more reliable while reducing electromagnetic interference in the electric measuring channel during the measurement of the electric conductivity of samples.


	Cells for proppant conductivity studies API-61 cell is intended for proppant conductivity studies. To perform a measurement, proppant is placed between the two planes of the cell. A cell modeling a fracture is placed in a hydraulic press. A prepared pre-heated liquid is pumped through the proppant pack. At a fixed compression of the pack, the following parameters are measured: pressure difference, flow rate and fracture width. Details »
