WELLS

Advanced Multi-Well Pumping Test Analysis Tool

WELLS offers detailed aquifer drawdown simulations and variable-rate pumping test analysis using analytical methods and parameter estimation integration.

WELLS is a versatile C-based code for analyzing multi-well, variable-rate pumping tests. It simulates drawdown in confined, unconfined, and leaky aquifers, accounting for wellbore storage, complex pumping rates, and boundary conditions.

WELLS is available on GitLab

Analytical Solutions

WELLS computes the drawdown/hydraulic head at one or more predefined locations due to pumping at one or multiple locations in an aquifer. The computation is based on a variety of available analytical solutions.

The analytical solutions implemented in WELLS can be broadly classified in the following categories:

WELLS has been applied to the following studies:

  • Identification of Pumping Influences in Long-Term Water Level Fluctuations (Harp and Vesselinov, 2011)
  • Accounting for the influence of aquifer heterogeneity on spatial propagation of pumping drawdown (Harp and Vesselinov, 2011)
  • On simulation and analysis of variable-rate pumping tests (Mishra et al., 2011)

The code was originaly developed at the University of Mining & Geology, Sofia, Bulgaria in 1992 by Velimir V. Vesselinov (Monty).
