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:

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
Mendeley, Zotero, Papers, and othersThe style is either built in or you can download a CSL file that is supported by most references management programs.

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.

A journal article with 1 author
Marchio, E.A. 2015. My metamorphosis. Science (New York, N.Y.), 347, 206.
A journal article with 2 authors
Okamoto, S. & Millis, A.J. 2004. Electronic reconstruction at an interface between a Mott insulator and a band insulator. Nature, 428, 630–633.
A journal article with 3 authors
Cabernard, C., Prehoda, K.E. & Doe, C.Q. 2010. A spindle-independent cleavage furrow positioning pathway. Nature, 467, 91–94.
A journal article with 8 or more authors

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. 1978. Assessment of Testing Vertical Line Array Difar Sonobuoy AN/SS2-77. Washington, DC, U.S. Government Printing Office, PSAD-78-120.

Theses and dissertations

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

Doctoral dissertation
Kyriacou, A. 2011. A Method of Verification of the Total Treatment Time for the APBI (Accelerated Partial Breast Irradiation) Devices: Contura Multilumen Balloon and SAVI Applicator. Doctoral dissertation, Florida Atlantic University.

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
Dwyer, J. 2016. ’60s TV, Taxes and a Taste of Trump. New York Times, A16.

In-text citations

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

This sentence cites one reference (Marchio 2015).
This sentence cites two references (Okamoto & Millis 2004; Marchio 2015).

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

  • Two authors: (Okamoto & Millis 2004)
  • Three or more authors: (Le Goff et al. 2009)
