Citation Styles for Engineers

Many of your professors may ask you to use APA style guide. Our personal librarian to the College of Education has made an excellent guide and you can find it here. There are also some examples of APA citation style below.

However, you may be asked to use a more formal engineering styles. APA is great for sciences, but sometimes journals or professors prefer that you use a particular citation format that was developed specifically by them in order to get the kinds of information that they would look for if they needed to be able to easily find the information that has been cited. Please use the tabs on the left side menu to choose the one appropriate to your needs.

SPE Style

Examples of SEP Styles are as follows, and their entire style guide is linked here. More examples are also listed in this guide.

Conference Paper (-MS)
White, C. D. and Horne, R. N. 1987. Computing Absolute Transmissibility in the Presence of Fine-Scale Heterogeneity. Paper presented at the SPE Symposium on Reservoir Simulation, San Antonio, Texas, USA, 1–4 February. SPE-16011-MS.

Direct-to-Peer Papers (Non-Conference), Not Found On OnePetro
Johnson, B. 1990. Reservoir Management. Paper SPE 36514 available from SPE, Richardson, Texas.

Published Journal Article Not Available From OnePetro
Diamond, D. 1991. High Pressure Leaks and How to Plug Them. SPE J. 6 (1): 112–114.

Discussion/Reply to a Published Paper
Peaceman, D. W. 1990. Further Discussion of Productivity of a Horizontal Well. SPE Res Eng 5 (3):437–438. SPE-20799-DS.

NOTE: For papers that have the discussion/reply as a separate document, as in the above example, use individual discussion's SPE number, if different from that of main paper, but always use DOI of main paper. Most papers, however, will have the discussion/reply included in the paper’s online PDF and should just be cited as a section of the paper, as in the examples below.
