Abstract
The frac plug system includes a setting mandrel, a sleeve member, a sealing member, a cone assembly, and a slip device. The setting mandrel includes a plurality of fluid bypass slots. The sleeve member includes a sleeve body with an abutment end. The setting mandrel has a first configuration without fluid flow through the frac plug system, and a second configuration with fluid flow through the frac plug system. The methods of the present invention include running the frac plug system in the first configuration and the sealing member in an extended position for a first setting stage, moving the setting mandrel to the second configuration with the sealing member in an expanded position, and then returning the setting mandrel to the first configuration for a second setting state. If the placement is wrong, the method includes removing the frac plug system in the first setting stage.
