Cementing plug formed with high pressure seal

A method of displacing cement in a downhole well environment, the method comprising:

• propelling a bottom plug into the downhole well environment;
• pumping cement into the downhole well environment above the bottom plug;
• forcing the cement through the bottom plug by propelling a top plug into the downhole well environment above the cement;
• and
• creating a hydraulic seal between the bottom plug and another device;
• wherein the bottom plug comprises:
• an insert layer;
• an outer layer encompassing a section of the insert layer, the outer layer having a sealing surface and at least one wiper;
• and
• the sealing surface having a first profile and a second profile formed therein, the first profile radially offset from the second profile, the first profile is a semi-circular profile or a line profile, the second profile is a semi-circular profile or a line profile;
• wherein the plug has a center axis in a plane extending along a length of the plug;
• wherein the first profile and the second profile are both positioned adjacent to one another on an exterior surface of a bottom of the plug;
• the sealing surface being perpendicular to the axis of the plug;
• wherein the sealing surface creates a hydraulic seal on a surface of another device when under pressure.

• wherein the first profile and the second profile are both positioned adjacent to one another on an exterior surface of a bottom of the plug;
• the sealing surface being perpendicular to the axis of the plug;
• wherein the sealing surface seals against a flat surface;
• and
• a top plug;
• wherein the sealing surface, in response to receiving the top plug, creates a hydraulic seal with a landing collar.
