Drilling engineers require estimates of the fluid pressures that they are likely to encounter in any given well to anticipate mud weights required to maintain optimal drilling rates and safety. In addition, the locations of anomalous pore-pressure regions are of interest in exploration because they often correlate with highly productive “sweet” spots in otherwise tight gas sands.&nbsp;[http://petrowiki.org/Pore%20pressure%20prediction%20using%20seismic Learn &nbsp;more....]

Offshore and Subsea Facilities

In 1859, Col. Edwin Drake drilled and completed the first known oil well near a small town in Pennsylvania, U.S.A. This well, which was drilled with cable tools, started the modern petroleum industry. In 1897, near Summerland, California, U.S.A., H.L. Williams extended an offshore oil field into the Santa Barbara Channel by drilling a submarine well from a pier. This first offshore well was drilled just 38 years after Col. Drake’s well. Five years later, more than 150 offshore wells were producing oil. Production from the California piers continues today.

In the late 1920s, steel production piers, which extended 1/4 mile into the ocean at Rincon and Elwood, California, were built, and new high-producing wells stimulated exploration activity. In 1932, a small company called Indian Petroleum Corp. determined that there was a likely prospect about 1/2 mile from shore. Instead of building a monumentally long pier, they decided to build a portion of a pier with steel piles and cross-members. Adding a deck and barging in a derrick completed the installation. By September 1932, the 60 × 90-ft "steel island" was completed in 38 ft of water. This was the first open-seas offshore platform and supported a standard 122-ft steel derrick and associated rotary drilling equipment. In January 1940, a Pacific storm destroyed the steel island. During the subsequent cleanup, divers were used for the first time to remove well casing and set abandonment plugs.

Meanwhile, the first offshore field was discovered in the Gulf of Mexico in 1938. A well was drilled to 9,000 ft off the coast of Texas in 1941. With the start of World War II, however, offshore activities came to a halt. Activity did not resume until 1945, when the state of Louisiana held its first offshore lease sale. In 1947, the first platform "out of sight of the land" was built off the coast of Louisiana in 20 ft of water.

What is PetroWiki?


PEH all.png

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. Disclaimer

Start your first page here!


Start creating your first article by logging in and using the search box to look for the topic of your choice. We recommend using the title of a page you would like to create in the search box. If the search does not return any relevant pages, you will be asked to start a new page. You can click on the red link and it will open a new page with you title to begin. Add your content and remember to save!

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, if there is not a relevant topic page you will be asked if you want to start a new page
  • Make changes and/or add content
  • Save

Suggested additions:

  • New and emerging concepts
  • Utilize your expertise to review, update, and enhance the quality of existing content
  • 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
