Variable-rate pumping analysis simulator
WELLS is a code for multi-well variable-rate simulations. It is based on analytical solutions. It supports confined, unconfined, and leaky aquifers; fully or partially penetrating wells; and pumping-well storage. Variable-rates are represented as step or piecewise-linear rates, as well as exponential and sinusoidal signals.
- Principle of superposition for multiple sources/sinks and transients.
- Method of images for constant-head and no-flow boundaries.
- Temporal trends (linear/exponential) to capture non-pumping influences.
- Simulation workflow tested and deployed on cloud resources, supercomputers, and desktops (Windows/Linux/macOS).
- Can be coupled with calibration/UQ tools such as our own software, MADS.
WELLS has both C and Julia implementations.
Example simulation of transient capture zones for two wells with time-varying pumping rates.
