Geochemical Analysis of a Multi-Layer Hydrocarbon Reservoir in the Wuerhe Area, Junggar Basin

Round 1

Reviewer 1 Report

I have gone through the manuscript and found it interesting work. I believe the work needs improvement in terms of presenting it to broader audiences. The introduction part is weak and needs to incorporate some more research work in different parts of the world. So, cite these research works.

These research articles will be helpful in improving the beginning of the introduction. How this study was conducted (2-3 lines about material and method) is not mentioned in the introduction.

Figure 3a needs improvement in resolution to overcome the readability issue.

Too much text in Table 1, Please try to use less text in the table. (Table 2 and 3 are perfect).

The conclusion needs improvements. Implications of the study need to stand out.

GOOD LUCK

Author Response

Dear editorial,

 Thank you for your comments on my article.

The preface of the manuscript has been revised and improved, and the references you gave have been added.

Figure 3 becomes clear as a whole, and the resolution is improved for easy reading.

Tables 1 and 2 have also been partially modified, and the conclusion has also been improved.

Thanks again.

Reviewer 2 Report

The manuscript presents the results of organic geochemical analyses of Permian petroleum source rocks, and light oils, light and heavy oils from Triassic and Jurassic reservoirs and Cretaceous solid bitumen of the Wuerhe area, northwest Junggar Basin, Xinjiang Uygur Autonomous Region.

Analyses and interpretations follow conventional standard procedures and are essentially acceptable.

A Table with detailed analytical data of all samples should be provided (in the Appendix). Table 3 only contains the results for 9 samples.

Moderate changes in English language/terminology are required, some (not all) of which are indicted in the attached annotated manuscript.

Dear editorial,

Thank you for your comments on my article.

The preface of the manuscript has been modified and improved.

The geochemical data of some key well locations are selected for this data, which is very representative. We also polished the language of the article.

Thanks again.
