A pair of blades in a shear ram of a blow-out preventer for cutting a tubular includes an upper blade and a lower blade. The lower blade shears the tubular in concert with the upper blade, the lower blade having a multi-point geometry to initiate shearing the tubular. The upper blade guides the tubular into a pocket-like geometry opposite the multi-point geometry of the lower blade. A blow-out preventor includes a blind ram, a shear ram, and a pipe ram, each including two ram blocks configured to extend into a bore to seal a bore. The shear ram includes an upper blade and a lower blade, where the lower blade shears the tubular in concert with the upper blade, the lower blade having a multi-point geometry to initiate shearing the tubular, the upper blade to guide the tubular into a pocket-like geometry opposite the multi-point geometry of the lower blade.
A pair of blades to be provided in a shear ram of a blow-out preventer for cutting a tubular, the pair of blades comprising:
A blow-out preventer comprising:
A method of shearing a tubular, comprising:
The method of 13, further comprising containing the tubular within an inner profile of the cavity using guide arms positioned on opposite sides of the pocket-like geometry, wherein the guide arms prevent expansion of the tubular out of the pocket-like geometry during shearing.
