A shear ram assembly apparatus for providing the capability to shear larger diameter well casings and internal components during ram-type blowout preventer operation while requiring less force to perform the cutting. Components of the shear ram assembly apparatus, include but not limited to a plurality of hardened cutting blades that are coated with a compound that increases the hardness and reduces the coefficient of friction of the cutting blades. In this regard, a smaller force is required to perform the cutting and the cutting blades receive less wear per cut and provide greater assurance that each cut of this failsafe apparatus is successful.
A shear ram assembly apparatus for operation in a ram-type blowout preventer, said apparatus comprising:
A ram-type blowout preventer (BOP) comprising:
A method for reducing the force required to shear an oilfield tubular and preventing deformation of a cutting blade associated with said ram-type blowout preventer (BOP), said method comprising:
