X-ray transparent coreholders

X-ray transparent coreholders are used in X-ray scanners and tomographs to study core saturation. There are different design versions to apply either 2D or 3D compression of core.

The coreholder design is a Hussler tube with pressure outlet ports along the core. The outer housing is a dural tube wrapped with carbon and glass fiber. In a linear scanner, unlike tomographs, 4 additional metal pins are used for axial pressure compensation to reduce the walls of the dural tube.

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.
