WellWiki provides data, news and history on 2 million oil and gas wells and counting... Eventually, we plan to provide data on all oil and gas wells ever drilled in North America – an estimated 4 million wells since the Drake well in 1859.

Find information about a well by searching its well number (e.g., 100.01-01-002-26W1), geographic location (e.g., Division No. 5, Manitoba), or operating company name (e.g., Omega Hydrocarbons Ltd.) and other details. Each well is identified by its well number and given a “well page" which provides information on location, permits, associated well pad, spudding and drilling information, violation and inspection data, production data, and waste information. A well page also links to the municipal community hosting that well and the operating company that owns that Well.
