Quantification of LNAPL Transmissivity in Fractured Porous Media
Monday, October 2, 2017: 10:00 a.m.
Light Non-Aqueous Phase Liquid (LNAPL) transmissivity is a metric to quantify the hydraulic recoverability of LNAPL. Existing methods to measure LNAPL transmissivity are applicable to granular porous media and often fail to reliably quantify LNAPL transmissivity in fractured porous media. LNAPL transmissivity calculations in fractured porous media require measurement of the geometry and discharge rate for individual fractures containing mobile LNAPL. A modification of methods designed for granular porous media has been developed to provide improved measurement of LNAPL transmissivity in fractured porous media at the individual fracture and aggregate well scales. A second benefit of the process is the high resolution definition of individual fractures containing mobile LNAPL.
