Hydraulic pumping

Hydraulic pumping is a proven artificial lift method that has been used since the early 1930s. It offers several different systems for handling a variety of well conditions. Successful applications have included setting depths ranging from 500 to 19,000 ft and production rates varying from less than 100 to 20,000 B/D. Surface packages are available using multiplex pumps ranging from 15 to 625 hp. The systems are flexible because the downhole-pumping rate can be regulated over a wide range with fluid controls on the surface. Chemicals to control corrosion, paraffin, and emulsions can be injected downhole with the power fluid, while fresh water can also be injected to dissolve salt deposits. When pumping heavy crudes, the power fluid can serve as an effective diluent to reduce the viscosity of the produced fluids. Read more....

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?

The Petroleum Engineering Handbook was published in 2006-2007. Therefore, some of the content is outdated and newer technologies may not be included.

  • 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
  • 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.

Content categorization - most pages in PetroWiki do not currently have categories assigned to them. SPE is in the process of finalizing a technical taxonomy that will be used for PetroWiki, OnePetro, and other SPE content. Once the taxonomy is final, categories will be added to PetroWiki pages.
