Abstract Hydraulic tomography (HT) has been shown to be a robust approach for the high‐resolution characterization of subsurface heterogeneity. However, HT can yield smooth estimates hydraulic parameters when pumping tests and drawdown measurements are sparse, thus limiting utility results in predicting groundwater flow solute transport. To overcome this issue, study integrates cross‐hole flowmeter with analysis steady‐state pumping/injection test data three‐dimensional (3‐D) conductivity (...
Abstract Significant efforts have been expended for improved characterization of hydraulic conductivity ( K ) and specific storage S s to better understand groundwater flow contaminant transport processes. Conventional methods including grain size analyses (GSA), permeameter, slug, pumping tests utilized extensively, while Direct Push‐based Hydraulic Profiling Tool (HPT) surveys developed obtain high‐resolution estimates. Moreover, inverse modeling approaches based on geology‐based...
Analyses are presented of long-term hydrographs perturbed by variable pumping/injection events in a confined aquifer at municipal water-supply well field the Region Waterloo, Ontario (Canada). Such records typically not considered for test analysis. Here, water-level variations fingerprinted to rate changes using Theis model implemented WELLS code coupled with PEST. these yield set transmissivity (T) and storativity (S) estimates between each monitoring production borehole. These individual...
This study proposes the utilization of municipal well records as an alternative dataset for large-scale heterogeneity characterization hydraulic conductivity () and specific storage using tomography (HT). To investigate performance HT feasibility utilizing records, a three-dimensional aquifer/aquitard system is constructed synthetic groundwater flow solute transport experiments are conducted to generate data inverse modeling validation results. In particular, we simultaneously calibrate four...
Horizontal drilling is the major method of shale gas extraction, and hydraulic fracturing improves production effectively. However, as main migration channel, microstructures, such natural fractures pores, are extremely complicated, it difficult to characterize them quantitatively by conventional approaches. Besides, microstructural evolution fracture (HF) area more intricate. In order microstructure after fracturing, investigate contribution extraction process, a fully coupled fractal...
