Claim:
1. An angle-cut shear ram blowout preventer (BOP) system to be used over a well when drilling for hydrocarbons through subterranean geological formations, during a blowout, the angle-cut shear ram blowout preventer (BOP) system is configured to simultaneously sever a heavy wall drill pipe in the well and seal the well once the heavy wall drill pipe is severed without requiring additional downhole tools, the angle-cut shear ram blowout preventer (BOP) system is installed on a blowout protector housing having a through bore, the through bore containing the heavy wall drill pipe, the heavy wall drill pipe extending between the well and a surface, the angle-cut shear ram blowout preventer (BOP) system comprising: a. a ram housing with a ram housing bore, wherein the ram housing is secured to the blowout protector housing, and wherein the ram housing bore intersects with the through bore; b. a ram cylinder pressure housing secured to the ram housing, wherein the ram cylinder pressure housing is fluidly connected to a hydraulic pressure source or a pneumatic pressure source; c. a piston in the ram cylinder pressure housing, wherein the piston is aligned with the ram housing bore, wherein the piston is fluidly connected to the hydraulic pressure source or the pneumatic pressure source; d. a moveable rod connected to the piston, at least partially within the ram cylinder pressure housing, moveable from a retracted position to an extended position in the ram housing bore; and e. an angle-cut shear ram connected to the moveable rod, wherein the angle-cut shear ram comprises:
