pyGeoPressure: Tools for geopressure prediction

A Python package for pore pressure prediction using well log data and seismic velocity data.

Features

1. Overburden (or Lithostatic) Pressure Calculation
2. Eaton's method and Parameter Optimization
3. Bowers' method and Parameter Optimization
4. Multivariate method and Parameter Optimization

Getting Started

Installation

pyGeoPressure is on PyPI:

pip install pygeopressure

Example

Pore Pressure Prediction using well log data

import pygeopressure as ppp

survey = ppp.Survey("CUG")

well = survey.wells['CUG1']

a, b = ppp.optimize_nct(well.get_log("Velocity"),
                        well.params['horizon']["T16"],
                        well.params['horizon']["T20"])
n = ppp.optimize_eaton(well, "Velocity", "Overburden_Pressure", a, b)

pres_eaton_log = well.eaton(np.array(well.get_log("Velocity").data), n)

fig, ax = plt.subplots()
ax.invert_yaxis()

pres_eaton_log.plot(ax, color='blue')
well.get_log("Overburden_Pressure").plot(ax, 'g')
ax.plot(well.hydrostatic, well.depth, 'g', linestyle='--')
well.plot_horizons(ax)
