Today, I continue to improve the paper and complete about 60%.
Summary:
I start to analyze the petrophysical and statistical part.
Tomorrow, I will try to finish the paper.

complete about 40% of the improvement
Today, I continue to improve the paper and complete about 40%.
Summary:
I mainly do replotting, recalculation, looking for citations, and adding some parts.
Tomorrow, I will continue to change the paper.

check all wells
Today, I checked all wells to see the difference of accuracy of predicting permittivity dispersion.
Summary:
I checked them one by one and found that they are all worse than the total database of the well.
So I think lithologies at different depths is not the main reason for poor and good prediction performance of permittivity dispersion.
The first figure is NMRSE result of well 1 (6 different lithologies).
The second figure is R2 result of well 1 (6 different lithologies).
Next week, we can discuss about our second paper when you have time.

finish the final draft of the second paper
Today, I finished the draft of the second paper.
Summary:
I have checked different lithologies one by one in well 1 and find that all results are worse than the total one, so i think lithologies at different depths may not be same main reason.
I conclude 2 reasons in our paper:
1. fewer data samples
2. high water salinity
Details can be seen in the draft that I sent to you.
Tomorrow, maybe we can discuss which Journal we can submit our paper to and change the format for submitting. Also, we can continue to improve our paper if you have more suggestions.

finish applying models
Today, I finished applying models to different wells.
Summary:
I finished applying models to different wells.
I am now analyzing some problems:
1. why prediction performance in well 3 is bad?
2. why prediction of cond is always better than perm?
3. why NRMSE is better than R2 for estimation of accuracy?
Tomorrow, I will try to finish all the analyzing parts.

do the second task left last week and finish half of them
Today, I did the second task left last week and finished half of them.
Summary:
I trained and tested the third method in well 1 and apply it in well 2. I will finish the opposite tomorrow.
Tomorrow, I will continue to change the second paper.

leave two tasks
Today, I improved all other parts except two tasks.
Summary:
Two tasks:
1. Evaluation of NRMSE and R2 and their explanation
2. Train and test the third method in well 1 and apply it in well 2 and vice versa
Next week, I will try to find good explanation of NRMSE and R2 and realize the application of the third method in 2 wells.
