How to format your references using the Petroleum Geoscience citation style

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:

Paperpile	The citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNote	Download the output style file
Mendeley, Zotero, Papers, and others	The style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeX	BibTeX syles are usually part of a LaTeX template. Check the instructions to authors if the publisher offers a LaTeX template for this journal.

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.

Ambros, V. 2004. The functions of animal microRNAs. Nature, 431, 350–355.

A journal article with 2 authors

Wang, Y. and Pfeiffer, J.K. 2014. Microbiology: a backup for bacteria. Nature, 516, 42–43.

A journal article with 3 authors

Morais-Cabral, J.H., Zhou, Y. and MacKinnon, R. 2001. Energetic optimization of ion conduction rate by the K+ selectivity filter. Nature, 414, 37–42.

Reports

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. 2003. Highway Safety: Research Continues on a Variety of Factors That Contribute to Motor Vehicle Crashes. GAO-03-436.

Theses and dissertations

Theses including Ph.D. dissertations, Master's theses or Bachelor theses follow the basic format outlined below.

Doctoral dissertation

Kramer, J.A. 2010. Accurate Localization Given Uncertain Sensors. Doctoral dissertation, University of South Florida.

News paper articles

Unlike scholarly journals, news papers do not usually have a volume and issue number. Instead, the full date and page number is required for a correct reference.

New York Times article

Hubbard, B. 2017. At a ‘Defense’ Expo, an Antiseptic World of Weaponry. New York Times, A4.

In-text citations

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

This sentence cites one reference (Ambros 2004).
This sentence cites two references (Ambros 2004; Wang and Pfeiffer 2014).

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

Two authors: (Wang and Pfeiffer 2014)
Three or more authors: (Grice et al. 2005)
