System and method for severing a tubular

A blowout preventer for severing a tubular of a wellbore, the blowout preventer comprising:

• a housing having a bore therethrough for receiving the tubular;
• an actuator positionable in the housing;
• and
• a plurality of cutting tools positionable in the housing and selectively movable into an actuated position with the actuator, each of the plurality of cutting tools comprising:
• a base supportable by the actuator and selectively movable thereby;
• and
• a cutting head supported by the base, the cutting head comprising a tip having a piercing point at an end thereof and at least one cutting surface, the piercing point for piercing the tubular, the at least one cutting surface tapering away from the piercing point for cutting through the tubular whereby the cutting head passes through the tubular.

A method of severing a tubular of a wellbore, the method comprising:

• positioning a BOP about the tubular, the BOP comprising a housing and an actuator;
• positioning a plurality of cutting tools in the housing, each cutting tool comprising:
• a base supportable by the actuator and selectively movable thereby;
• a cutting head supported by the base, the cutting head comprising a tip having a piercing point at an end thereof and at least one cutting surface that tapers away from the piercing point;
• selectively moving the plurality of cutting tools to an actuated position with the actuator such that the cutting head passes through the tubular by piercing the tubular with the piercing point and cutting through the tubular with the at least one cutting surface.
