Combining Well Log Data With Formation Tops in Python for Petrophysics

[@mahammadodj]

Thanks! I actually did it using merge,sorting and forward filling functions. Your solution is straightforward.

It was quite helpful for me! Thanks!

Great to hear 👍

Thank you for taking the time on doing these videos! this is really helpful.. I was wondering if there is a library like Lasio that could do the same in reading a DLIS file to pull the arrays and index them against depth. thank you!

Hi Andy, Could you please help me in this. I have a dataframe with multiple wells having log curve data along with DEPTH and Well Name as two column. Now i want to create a flag column into this dataframe based on depth falling in any of the pay zone interval (for each well 3-4 intervals are there, mentioned in excel) for that particular well mentioned in an excel sheet. How can i do this? Thank you in advance.

great work!

You ought to consider one regarding python scripts in techlog

Thanks good stuff. I am dealing with multiple wells with formation tops- I have to sort out how we do it

I am hoping to have a video available on this topic soon

Hi Andy! Thanks for the nice content. Can you please let me know How can i apply same function on multiwell las data (saved in one csv). Similarly i have FM tops csv for multiple wells (I have common UWI in both CSV)

Hi Nusrat. Sorry for the late reply. I have just published a medium article on this very topic. I am hoping to do a video on it soon. You can check out the article below ⬇️ andymcdonaldgeo.medium.com/creating-an-multi-well-integrated-well-log-and-formation-tops-dataframe-in-python-469670550aaf

@@AndyMcDonald42 Thank you!

This is really interesting and helpful. Could you please share your thoughts how would the function look like if we are dealing with multiple wells in the same spread sheet and we want to assign the samples to formations? Thanks so much for sharing all these amazing videos ❤😊

[@AndyMcDonald42]

Thanks. 👍 There are a few ways I can think of on how to deal with this. Assuming you have a well log dataframe with multiple wells you will likely have a well name column. I would then ensure that the formation tops spreadsheet also has a well name column. The function could then be changed to include a lookup to check that the well names match before adding in the formations to the dataframe. I may do a video on this in the near future.
