Oil and gas development in Eastern Montana

By Joe Kolman, research analyst

House Bill 790 required that the subcommittee study oil and gas regulations in Montana. The committee has seen a statewide map of oil fields, but in an effort to provide a more specific visual context, staff created maps showing well locations in Eastern Montana areas that may be discussed at the Sidney meeting.

Maps were created using well data maintained by the Board of Oil and Gas Conservation. Data are current through mid-November 2005. Wells shown include producing oil and gas wells, or those online to produce. Also depicted are wells plugged in accordance with MBOGC rules.
