This week's featured topic page Pressure transducer technology All pressure transducers operate on the principle of converting a pressure change into a mechanical displacement, or deformation. Deformation of the sensing element is then converted into an electrical signal that is processed by the measuring system. Types of pressure transducers available in the field, either individually or in combination, are mechanical, capacitance, strain gauge and quartz gauge. This article discusses how each of these types of pressure transducers operate. The first pressure transducers had mechanical-force-summing elements that converted energy into mechanical displacement, or deformation, and then coupled the generated force to a recording device. In the Amerada gauge, a popular mechanical pressure transducer, the pressure-sensing element is a helical Bourdon tube. 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 Therefore, some of the content is outdated and newer technologies may not be included.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 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 - 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.

How do I use PetroWiki? Search box Use the search box at upper right to find content of interest. PetroWiki is indexed by search engines, so you also may find content of interest through your favorite search engine. Glossary Use the Glossary to find terms and definitions. Help Use the Help to locate guides, videos, and slideshows to explain editing. Translator English not your first language? You'll find Google Translate in the navigation under Toolbox. While the translations are far from perfect and technical terms may not translate well, it may help with understanding.
