How to format your references using the Petroleum Science citation style

This is a short guide how to format citations and the bibliography in a manuscript for Petroleum Science. 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	Find the style here: output styles overview
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.

A journal article with 1 author

Gandhi KJK. The best decision I ever made. Science. 2015 Nov 27;350(6264):1122.

A journal article with 2 authors

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. Tribal Transportation: Better Data Could Improve Road Management and Inform Indian Student Attendance Strategies. Washington, DC: U.S. Government Printing Office; 2017 May. Report No.: GAO-17-423.

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

Doctoral dissertation

Boyer MD. Organizational improvisation within an episodic planning model: A systems perspective [Doctoral dissertation]. [Minneapolis, MN]: Capella University; 2009.

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

In-text citations

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

This sentence cites one reference (Gandhi 2015).
This sentence cites two references (Gandhi 2015; Huang and Grant 2013).

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

Two authors: (Huang and Grant 2013)
Three or more authors: (O’Connor et al. 2000)
