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

Friedman N. Inferring cellular networks using probabilistic graphical models. Science. 2004 Feb 6;303(5659):799–805.

A journal article with 2 authors

Tierney JE, deMenocal PB. Abrupt shifts in Horn of Africa hydroclimate since the Last Glacial Maximum. Science. 2013 Nov 15;342(6160):843–6.

A journal article with 3 authors

Jansens A, van Duijn E, Braakman I. Coordinated nonvectorial folding in a newly synthesized multidomain protein. Science. 2002 Dec 20;298(5602):2401–3.

A journal article with 7 or more 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. Tax Systems Modernization: Results of Review of IRS’ Third Expenditure Plan. Washington, DC: U.S. Government Printing Office; 2001 Jan. Report No.: GAO-01-227.

Theses and dissertations

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

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

Herrman J, Isaac M. Counting Views Is Not as Easy as 1, 2, 3. New York Times. 2016 Oct 3;B2.

In-text citations

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

This sentence cites one reference (Friedman 2004).
This sentence cites two references (Friedman 2004; Tierney and deMenocal 2013).

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

Two authors: (Tierney and deMenocal 2013)
Three or more authors: (Kim et al. 2007)
