Hydrostatic Core Holders

Pressure-Tapped Hydrostatic Core Holder

Manufacturer: Vinci Technologies
Model Number: PT-HYC

The PT-HYC Series core holders are Hydrostatic type core holders which are equipped with a number of pressure taps molded in the sleeve at discrete locations required by the end user. This design allows to monitor the pressure drop along the length of the core sample during fluid flow tests. The coreholder has a fixed platen at one end over which the rubber sleeve is mounted and located in the other end of the sleeve is a floating platen connected via a ¼” diameter tubing passing through the outside. For variable length cores, this design insures solid contact between the platen and core sample. To change a core sample the confining fluid must be drained off and the knurled screwed ring removed by rotating anti clockwise by hand. This will withdraw the fixed platen together with the sleeve, core and floating platen. After removal of the two platens from the sleeve the core can be withdrawn. Loading a new core sample is carried out in the reverse order. The advantage of this type of coreholder is that the overburden pressure acts on the end of the core as well as the diameter.



Hydrostatic Core Holder

Model Number: HYC

The HYC Series core holders are standard hydrostatic type core holders in which radial and axial confining pressures are common. These core holders are routinely used for gas and liquid permeability testing and water flooding experiments. The coreholder has a fixed platen at one end over which the rubber sleeve is mounted and located in the other end of the sleeve is a floating platen connected via a ¼” diameter tubing passing through the outside. For variable length cores, this design insures solid contact between the platen and core sample.

The coreholder can be equipped with a number of pressure taps molded in the sleeve at discrete locations required by the end user. This design allow to monitor the pressure drop along the length of the core sample during fluid flow tests. Electrical pressure tap can also be provided to monitor the resistivity of the core sample during a permeability test.
