Well‐Type Steady Flow in Strongly Heterogeneous Porous Media: An Experimental Study

Steady well-type flow was monitored in an aquifer that artificially packed order to reproduce a given, highly heterogeneous, statistical distribution of the log-conductivity Y. In particular, we focus on pumping tests carried out at 10 volumetric rates. The experimental arrangement composed by well and several surrounding observation piezometers. unique feature this study is high heterogeneity structure Y known fairly well. Thus, lends itself as valuable tool corroborate theoretical findings about flows driven sources through porous formations, where variance (in present equal 3.79) large. Besides discussing findings, tackle crucial issue upscaling hydraulic conductivity well-flow configuration. deal with equivalent (EC) pertaining homogeneous (fictitious) medium which conveys same rate real one, under boundary conditions. Hence, EC can be identified straightforwardly means head measurements. Even if show proper parameter measurements, it experimentally shown line results) position-dependent, therefore, cannot regarded (unlike groundwater-type flow) formation’s property. This implies applies only configuration stake. Then, EC, combined recent model effective well-flows heterogeneous formation, leads reasonably reliable estimate , some limitations approximations, notwithstanding. It hoped will useful for other researchers who are engaged similar research-topics.
