Features

• Programmatically fit observation wells to reference wells

• Visualize fits and deviations

• Save your work, share and pick up later with a custom .gwref file format

• Work with live data and update your analysis as new data comes in

Quick Example

Python

In this example an observation well and reference well are fitted and plotted.

# Import the packages
import gwrefpy as gr
import pandas as pd

# Load timeseries data from CSV files
obs_data = pd.read_csv("obs.csv", index_col="date", parse_dates=["date"]).squeeze()
ref_data = pd.read_csv("ref.csv", index_col="date", parse_dates=["date"]).squeeze()

# Create Well objects and add timeseries data
obs = gr.Well(name="12GIPGW", is_reference=False)
obs.add_timeseries(obs_data)

ref = gr.Well(name="45LOGW", is_reference=True)
ref.add_timeseries(ref_data)

# Create a Model object, add wells, and fit the model
model = gr.Model(name="Small Example")
model.add_well([obs, ref])

model.fit(obs_well=obs, ref_well=ref, offset="0D", tmin="2020-01-01", tmax="2020-03-23")

# Plot the results
model.plot_fits(plot_style="fancy", color_style="color", show_initiation_period=True)
