generating new curves

[jjpantano]

I have written down some additional capabilities that can build off https://toddheitmann.github.io/PetroPy/index.html# This needs more refinement and post to inquiry about possible collaboration.

log.fluid_properties_parameters (read_csv) generate_fluid_property_curves edit_fluid_property_curves (optional) generate_fluid_property_curves formation_multimineral_model

generate_list_of_curves generate_list_of_calculations (read_csv) select_calculation(s) select_well(s) map_function_arguments_to_curves assign_values_for_arguments_for_no_curves generate_new_curve(s)

Hi John, I'm going back to this today. Don't think it will make it into the app, but if theres a working proof of concept by the end of the hackathon I'll continue this work and add a 'petrophysics' module.

I went throught the Petropy stuff yesterday, and whilst there's some functions we can use there's some that we can't with this data. Most of the functions have inputs that we don't have with this dataset, so a rewrite would be needed with optional functionality, I'd do this via **kwargs but open to other suggestions. For example if PHI=Null, then compute from density, or another curve etc and print a warning/statement.

https://toddheitmann.github.io/PetroPy/_modules/petropy/log.html#Log.fluid_properties uses default properties if args are null/not entered. But that's also pretty incomprehensible, and a lot of the input properties can be calculated. For example in that code:

RW : (ohm.m) Resistivity of water RMF : (ohm.m) Resistivity of mud filtrate RHO_HC : (g / cc) Density of hydrocarbon RHO_W : (g / cc) Density of formation water RHO_MF : (g / cc) Density of mud filtrate NPHI_HC Neutron log response of hydrocarbon NPHI_W Neutron log response of water NPHI_MF Neutron log response of mud filtrate MU_HC : (cP) Viscosity of hydrocarbon Z Compressiblity factor for non-ideal gas. Only output if oil_api = 0 CG : (1 / psi) Gas Compressiblity. Only output if oil_api = 0 BG Gas formation volume factor. Only output if oil_api = 0 BP : (psi) Bubble point. Only output if oil_api > 0 BO Oil formation volume factor. Only output if oil_api > 0

Can all be calculated for only 6 required inputs; Pressure, Temperature, Salinity, Rmf at surface/pad, mf density, HC gravity/api.

you all did a great job ... I hope that I can contribute at keeping this going. Cheers John
