This week's featured topic page

Pressure transient testing

The interpreted pressure transient test is a primary source of dynamic reservoir data. Tests on oil and gas wells are performed at various stages of drilling, completion, and production. The test objectives at any stage range from simple measurement of reservoir pressure to complex characterization of reservoir features. Most pressure transient tests can be classified as either single-well productivity tests or descriptive reservoir tests. Learn more....

In the news this week

New topic pages

New pages are continually added to PetroWiki. These new pages always need subject experts to help develop these pages into high quality resources. With so many different roles within PetroWiki that have to do with contributing there is undoubtedly a place that will fit perfectly with your expertise and time. Read more about becoming a champion for PetroWiki…

Featured New Page
Producing crude oil from algae


Biofuels are an alternative to fossil fuels that are produced from fats derived from living organisms. One source of biofuel that is being explored more thoroughly in recent years is microalgae. The bio substance can be turned into crude oil, which can then be used to create biodiesel, biobutanol, biogasoline, methane, ethanol, or jet fuel.

What is PetroWiki?

PetroWiki was created from the seven volume Petroleum Engineering Handbook (PEH) published by the Society of Petroleum Engineers (SPE). PetroWiki preserves the PEH content in unaltered form (page names that start with PEH:), while allowing SPE's membership to update and expand content from the published version. Pages that do not have PEH: at the beginning may have started with content from the PEH, but have been modified over time by contributors to the wiki.

Content in PetroWiki is moderated by at least two members with subject matter expertise. This helps to ensure that the information found in PetroWiki is technically accurate. Disclaimer

Unlike some other online wikis, PetroWiki content is copyright SPE. For information about using content from PetroWiki, see PetroWiki:Permissions.

How can I contribute to PetroWiki?

PetroWiki is a living document and therefore the content should be enhanced to include newer technologies and current information.

  • Share your knowledge with others and help update PetroWiki at the same time! You can't "break" the wiki.
Follow these basic steps to get started:
Log in
Search for the topic of your choice
Open the topic page
Make changes
Save
  • Adding links to good papers in OnePetro and elsewhere is a great way to enrich existing content pages.
  • Creation of pages about specific fields are welcome. Knowing the basics of the reservoir and how the field was developed over time can provide valuable information to others. (See Prudhoe Bay field and Kuparuk River field as examples)
  • If you are an SPE professional member, you must log in. [Use your SPE website login.] Help with editing
  • Pages that start with PEH: cannot be edited.

For more information, see PetroWiki:Frequently asked questions

Content categorization - SPE has finalized a technical taxonomy that is being used in PetroWiki, OnePetro, and other SPE content.
