Scaling solutions for production analysis from unconventional oil and gas wells

bluebonnet

Scaling solutions for production analysis from unconventional oil and gas wells.

Installation

Run the command

pip install bluebonnet

This package works for Python versions 3.8-3.11. Dependencies are automatically installed by pip. They include standards of the Python scientific stack, including lmfit, matplotlib, numpy, pandas, and scipy.

Usage

bluebonnet has a collection of tools for performing reservoir simulation in tight oil and shale gas reservoirs. The main tools are:

1. fluids for modeling PVT and viscosity of oil, water, and gas;
2. flow for building physics-based production curves; and
3. forecast for fitting and forecasting unconventional production.

Examples can be found in the documentation.

Credits

This work was funded in part by an ExxonMobil grant to the University of Texas at Austin, with Michael Marder as PI and Larry Lake as co-PI. The Physics-based scaling curve was developed for shale gas reservoirs by Patzek et al. (2013). It was extended to tight oil by Male (2019). It was extended to two-phase by Ruiz Maraggi et al. (2020). It was extended to include variable fracture face pressure by Ruiz Maraggi et al. (2021). In the future, it might be extended further.
bluebonnet was created with cookiecutter and the py-pkgs-cookiecutter template.
