wellradpy 0.0.2

A small Python package to calculate the radius of influence and radius of investigation of wells.

WellRadPy

WellRadPy (Well Radius Python) is a small Python package for calculating the radius of influence and radius of investigation of wells. These quantities frequently need to be estimated in well hydraulics and aquifer testing.

There are various ways by which radius of influence and radius of investigation may be precisely defined. Accordingly, a large number of methods have been proposed for estimating radius of influence and radius of investigation. This package implements most existing methods.

The calculations rely on major simplifying assumptions. Specifically: 2D (horizontal) confined flow, infinite domain, homogeneous hydraulic properties, single-porosity media, and fully-penetrating well. Also, only single-phase Newtonian fluids that flow according to Darcy's law are considered.

A paper will (hopefully) soon be published with all the details.

Usage

WellRadPy is simple and its use is straightforward. There are just as many functions as there are ways to precisely define radius of influence and radius of investigation.

The /examples directory in the GitHub repository contains a script where all the functions are exemplified.

You can also help(whatever_function) in the Python console.

Installation

For simple use

1. From the command line, type pip install wellradpy. This will download the latest release of the package from the PyPI repository and install it.

For development

1. Clone (or download) the sources from the GitHub repository.
2. From the project directory, type pip install -e .. This will install the current directory, so that you can both modify the package and use it at the same time.

Dependencies

WellRadPy depends on the Python packages NumPy and SciPy (>= 1.2.0). These will be automatically installed with any of the above installation methods.
