This is a short guide how to format citations and the bibliography in a manuscript for Petroleum Geoscience. For a complete guide how to prepare your manuscript refer to the journal's instructions to authors.

Using reference management software

Typically you don't format your citations and bibliography by hand. The easiest way is to use a reference manager:

PaperpileThe citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNoteDownload the output style file

Journal articles

Those examples are references to articles in scholarly journals and how they are supposed to appear in your bibliography.

Not all journals organize their published articles in volumes and issues, so these fields are optional. Some electronic journals do not provide a page range, but instead list an article identifier. In a case like this it's safe to use the article identifier instead of the page range.

Smaglik, P. 2004. High road to Scotland. Nature, 432, 128–129.
A journal article with 2 authors
Walck, J. and Dixon, K. 2009. Time to future-proof plants in storage. Nature, 462, 721.
A journal article with 3 authors
Kolodner, R.D., Putnam, C.D. and Myung, K. 2002. Maintenance of genome stability in Saccharomyces cerevisiae. Science (New York, N.Y.), 297, 552–557.
A journal article with 8 or more authors

Web sites

Sometimes references to web sites should appear directly in the text rather than in the bibliography. Refer to the Instructions to authors for Petroleum Geoscience.

This example shows the general structure used for government reports, technical reports, and scientific reports. If you can't locate the report number then it might be better to cite the report as a book. For reports it is usually not individual people that are credited as authors, but a governmental department or agency like "U. S. Food and Drug Administration" or "National Cancer Institute".

Government report
Government Accountability Office. 2009. Federal Aviation Administration: Human Capital System Incorporates Many Leading Practices, but Improving Employees’ Satisfaction with Their Workplace Remains a Challenge. GAO-10-89.

Doctoral dissertation
Zhu, H. 2012. Outcomes of China Free Antiretroviral Treatment Program, 2003–2010. Doctoral dissertation, University of North Carolina.

News paper articles

New York Times article
Greenhouse, L. 2006. Court Veteran Remembers A Scary Start. New York Times, A31.

In-text citations

References should be cited in the text by name and year in parentheses:

This sentence cites one reference (Smaglik 2004).
This sentence cites two references (Smaglik 2004; Walck and Dixon 2009).

Here are examples of in-text citations with multiple authors:

  • Two authors: (Walck and Dixon 2009)
  • Three or more authors: (Chen et al. 2014)
