Model 4 - Pinchout

This script demonstrates how to create a geological model with a layer of varying thickness (pinchout) using GemPy, a Python-based, open-source library for implicit geological modeling.

# Import necessary libraries
import gempy as gp
import gempy_viewer as gpv


# sphinx_gallery_thumbnail_number = 3

Generate the model Define the path to data

data_path = 'https://raw.githubusercontent.com/cgre-aachen/gempy_data/master/'
path_to_data = data_path + "/data/input_data/jan_models/"
# Create a GeoModel instance
data = gp.create_geomodel(
    project_name='pinchout',
    extent=[0, 1000, 0, 1000, 0, 1000],
    resolution=[50, 50, 50],

        path_to_surface_points=path_to_data + "model4_surface_points.csv"
    )
)
# Map geological series to surfaces
gp.map_stack_to_surfaces(
    gempy_model=data,
    mapping_object={"Strat_Series": ('rock2', 'rock1')}

# Compute the geological model

Plot the initial geological model in the y direction

gpv.plot_2d(geo_data, direction=['y'], show_results=False)

# Plot the result of the model in the x and y direction with data
gpv.plot_2d(geo_data, direction=['x'], show_data=True)
gpv.plot_2d(geo_data, direction=['y'], show_data=True)
