WellWiki provides data, news and history on 4.3 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 5.8 million wells since the Drake well in 1859.
In partnership with Pembina Institute, we have incorporated detailed information for landowners on oil and gas development. Learn more in the Landowners Guide to Oil and Gas Development.
WellWiki has expanded its coverage by more than 2 million wells in the past year, bringing us to more than 4.3 million wells. We now cover 99% of all wells in Canada and nearly 3.5 million wells in 24 U.S. states. Learn all about our data sources.

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.
