Hydraulic tomography: 3D hydraulic conductivity, fracture network, and connectivity in mudstone
June 12, 2019
We present the first demonstration of hydraulic tomography (HT) to estimate the three-dimensional (3D) hydraulic conductivity (K) distribution of a fractured aquifer at high-resolution field scale (HRFS), including the fracture network and connectivity through it. We invert drawdown data collected from packer-isolated borehole intervals during 42 pumping tests in a wellfield at the former Naval Air Warfare Center, West Trenton, New Jersey, in the Newark Basin. Five additional tests were reserved for a quality check of HT results. We used an equivalent porous medium forward model and geostatistical inversion to estimate 3D K at high resolution (K blocks

MODFLOW-2005 groundwater flow models were developed to simulate 47 pumping tests conducted for a hydraulic tomography experiment in fractured rocks underlying the former Naval Air Warfare Center, West Trenton, New Jersey. These flow models simulate the change in water level during the pumping tests, which range from about 45 to 60 minutes in duration. MODFLOW-2005 models were also...
