Fig. 6From: Matrix permeability of reservoir rocks, Ngatamariki geothermal field, Taupo Volcanic Zone, New ZealandPore geometry measurements versus permeability at 5 MPa confining pressure for pore-dominated samples from NM 11 at 2083–2087.4 m depth. a circularity correlates with permeability; b aspect ratio, roundness, and vug porosity do not correlate with permeabilityBack to article page
