All manuscripts should be submitted to Petroleum Geology and Engineering through "Online Submission" on the journal's website (http://www.sydzygc.cn/indexen.htm). If you meet any problems concerning the submission, please contact us by e-mail to sydz@vip163.com.

Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all Authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, without the written consent of the copyright-holder.

Title

Be Concise and informative. Avoid abbreviations and formulae where possible.

Author names and affiliations

Provide the full postal address of each affiliation, including the country name.

First Author and Corresponding Authors

Provide a brief introduction about the first author. Clearly indicate who is willing to handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address of the corresponding author.

Abstract

A concise and factual abstract is required (maximum length 200 words). The abstract should state briefly the purpose of the research, the principal results and major conclusions.

Key Words

Immediately after the abstract, provide a maximum of 5 key words, avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible.

Subdivision of the Article

Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2), 1.2, etc. Any subsection should be given a brief heading. Each heading should appear on its own separate line.

References

References should be numbered consecutively in the order in which they are first mentioned in the text. Responsibility for the accuracy of bibliographic citations lies entirely with the authors. Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Only articles that have been published or are in press should be included in the references. Journal articles and books must be cited by the following formats:

For Journals: names of all the authors (surnames followed by initials), article title, name of periodical, year, volume number, issue number (in brackets), and range of pages.

For books: names of authors (surnames followed by initials), title, In: xxx ed(s)., book name, place of publication, publisher, year and range of pages.

Quantities and Units

All parameters, units and symbols to be used must conform to the national standard and relevant professional standard. Each physical quantity in a formula must be given its appropriate scientific designation and using recognized standard units.

Figures and Tables

The size of a figure or table should not be larger than a full page, and neither should be a plate (either color plate or white-black plate).

Footnotes

These should be included only when absolutely essential.
