Whois & Analysis for petrowiki.org

The Society of Petroleum Engineers (SPE) is a not-for-profit professional organization whose mission is to collect, disseminate, and exchange technical knowledge concerning the exploration, development and production of oil and gas resources and related technologies for the public benefit and to provide opportunities for professionals to enhance their technical and professional competence.

For petroleum refinery engineering, see Process engineering.

Petroleum engineering is a field of engineering concerned with the activities related to the production of hydrocarbons, which can be either crude oil or natural gas.

Exploration and Production are deemed to fall within the upstream sector of the oil and gas industry.

Exploration, by earth scientists, and petroleum engineering are the oil and gas industry's two main subsurface disciplines, which focus on maximizing economic recovery of hydrocarbons from subsurface reservoirs.

Petroleum geology and geophysics focus on provision of a static description of the hydrocarbon reservoir rock, while petroleum engineering focuses on estimation of the recoverable volume of this resource using a detailed understanding of the physical behavior of oil, water and gas within porous rock at very high pressure.

A wiki is a website that provides collaborative modification of its content and structure directly from the web browser.

In a typical wiki, text is written using a simplified markup language (known as "wiki markup") and often edited with the help of a rich-text editor.

A wiki is run using wiki software, otherwise known as a wiki engine.

There are dozens of different wiki engines in use, both standalone and part of other software, such as bug tracking systems.

Some wiki engines are open source, whereas others are proprietary.

Some permit control over different functions (levels of access); for example, editing rights may permit changing, adding or removing material.

Others may permit access without enforcing access control.

Other rules may also be imposed to organize content.

A wiki engine is a type of content management system, but it differs from most other such systems, including blog software, in that the content is created without any defined owner or leader, and wikis have little implicit structure, allowing structure to emerge according to the needs of the users.

Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop.

The system can then be said to feed back into itself.

The notion of cause-and-effect has to be handled carefully when applied to feedback systems:

Copyright is a legal right created by the law of a country that grants the creator of an original work exclusive rights for its use and distribution.

This is usually only for a limited time.

The exclusive rights are not absolute but limited by limitations and exceptions to copyright law, including fair use.

A major limitation on copyright is that copyright protects only the original expression of ideas, and not the underlying ideas themselves.
