Loading and Exploring Well Log LAS Files Using LASIO in Python

Log ASCII Standard or LAS Files are a commonly used format within the oil and gas industry. They are used to store and transfer geological, petrophysical, and well log data.

In this video, I show you what a LAS file is, what it contains and how to explore its contents using a Python library called lasio.

This video really saved my bacon when I had a short deadline and a .LAS file sent my way unexpectedly. Thanks for this valuable well-presented knowledge.

[wordofinformation]

but how to read the las files of version 3.0 please tell us

Thanks for sharing Andy..Will be nice to see mudlog ASCII data too ..👏👏

Great video! Great starting place for a person like me who's just starting to learn about las files

[pouyapadiav]

I really enjoyed it. It is the beginning of my freedom from using Techlog.

[viniitr]

Very useful content. Thanks for sharing👍

Mr Andy, Firstly accept my thanks for demonstrating wellog in to python notebook. I'm curious on the SEGY & ASCII file loading with the similar demo. Kindly provide the relevant links/video/github pages. Thanks in advance.

Is there any way for you to automate spike removal in log data?

[naufallhabib]

Thanks for sharing sir Andy, i got an issue with the well.plot command = not showing the curve plot. The output is : Axes(0.125, 0.11;0.775x0.77). Hope you can answer it while I'm finding the solution as well. 🙏🙏

Greetings Andy,
I work in a company that won't give me an access to Python (lasio), and sometimes I face issues while dealing with wrapping las files trying to export them into excel, do you know of any way I can resolve this issue using Excel or MATLAB? Also, I can't download any additional add-ons or packages to either.

[chibuzorahumaraeze]

The re-exporting of the las file isn't working.
las.write('Exports....')

[olaal-najjar]

Great job. But what is the code's script to display logs measurements vertically instead of horizontally? Thank you

[because]

Hi Everyone. I have a missing " Curve #4 'DT' is defined in the ~C section but there is no data in ~A"
Can you share me a solution?
Thank you so much!

[victorcruz]

Great video Andy! I was thinking about how usefull could it be for minning logs too

[jordaanfouche]

Hallo Andy

I have started working trough this. I am new to Python, Github and Jupyter Notebook. I am getting this error:
ModuleNotFoundError: No module named 'lasio' when I am trying to run your scrip. Or perhaps you do have a tutorial that explains these basic steps which I have could have missed. Please guide me.

[Dcelis]

Andy, Cool stuff. However the link for the notebook is not working apparently.

[hamedheidari]

Hi Andy,
Thanks for the nice video. I intend to watch the videos and use the lasio package. However, I couldn't install the package in Anaconda prompt, as I get some errors. Would you please let me know how to install the package properly?

[gustavoandrespinzonlandaza]

Hi Andy, I am trying to install Lasio but I got an error. ModuleNotFoundError: No module named 'lasio'

[jorgeparra]

Very Good Video Andy.
Is possible to modify the notebook by adding an option to write the logs (output) in an Excell file?

[mazenomar]

Is lasio automatically assign depth to be index or i have to do it manually.regards
