Multiphase flow through cleats in coal. Annual report, January-December 1993
Multiphase flow through cleats in coal. Annual report, January-December 1993 Effective cleat porosity, cleat aperture, cleat network interconnectedness, and absolute water permeability values were measured for Fruitland Formation coal cores from the San Juan Basin of Colorado and New Mexico. The mean coefficient of variance (expected percent error) value for seven sets of replicate unsteady state method effective cleat porosity measurements was 5.4%. The measured values of the effective cleat porosity obtained using Wood's metal porosimetry exhibited systematic negative bias compared to values obtained using the unsteady state helium/water displacement method. The bias occurs because the Wood's metal accesses a more limited pore size distribution than does the helium/water.
