§ 1723.1. Plugging of Oil or Gas Zones.
As a minimum for an open-hole plugging and abandonment, the special requirement shall include a cement plug extending from at least 100 feet below the top of the oil or gas zone to at least 100 feet above the top of the zone.
As a minimum for a cased-hole plugging and abandonment, the special requirement shall include a cement plug extending from at least 25 feet below the top of the uppermost perforated interval to at least 100 feet above the top of the perforations, the top of the landed liner, the casing cementing point, the water shutoff holes, or the zone, whichever is highest.
(d) Bridge Plug. In a multiple zone completion, a single bridge plug above the lowermost zone may be allowed in lieu of cement through that zone if the zone is isolated from the upper zones by cement behind the casing. Subsequent bridge plugs are not allowed unless separated by cement plugs meeting the requirements of Section 1723.1(b). Temporary bridge plugs must be removed and replaced with cement plugs prior to shallower zone completions or well abandonment.
