ABSTRACT:
A well blowout preventer packer that is assembled by means of modularly constructed and defined elements. The modular elements are assembled and interlocked individually without resorting to cementing them together whereby individual elements may be replaced when they deteriorate. The modular packer elements can be molded individually so that the elastomeric materials can be better controlled.
