Global Integrated Workshop Series - Production Forecasting

The 31 newly added Production Forecasting pages included in PetroWiki were created from a document written in 2014 and 2015 by a group of almost 50 experts and committee members. These members volunteered their expertise to integrate the learnings from the wealth of contributions and discussions during the workshops.

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.
