Pulse Decay Permeameter

Description

Measurement of gas permeability for tight rocks. The Wolfson multiphase flow laboratory has a CoreLab 200 PDP pulse-decay permeameter, which is basically an adaptation of the Brace design. The 200 PDP can accurately measure gas permeabilities of 0.1 mD to 10 nD. The equipment has core holders for 1 in and 1.5 in cores and was originally designed to operate at confining pressures of up to 2000 psi.
