Configured PetroPy formation evaluation

PetroPy 0.1.6 uses Log.fluid_properties() followed by Log.multimineral_model(). It does not provide the previously shown shale_volume, formation_porosity, water_saturation, permeability or to_las methods. Export a Log with write(...).

Environment and input contract

Use an isolated Python 3.11 environment with the metadata dependencies. The verified combination is PetroPy 0.1.6, lasio 0.30 and NumPy 1.26.4; lasio 0.32 removed add_curve, which PetroPy still calls. Old lasio 0.23/0.29 also fail with modern NumPy during header parsing. The cchardet prerelease has Python 3.11 wheels; dependency declarations in this skill do not install packages.
