US Patent 10494892 Multifunction downhole plug

A downhole plug and method of activating multiple downhole tools in a subterranean formation are disclosed. The plug includes a detachable ring that enables the plug to land in and engage at least two different seats, each seat having a different profile. This in turn enables the plug to activate at least two separate downhole devices, one in an upper downhole tool and one in a lower downhole tool. The ring separates from the plug once a certain pressure is reached in the wellbore enabling the plug to travel downhole from the upper tool to the lower tool to activate the device in the lower downhole tool.
