Abstract
A shear pig assembly and method of use for severing a linear conductor within a surrounding tubular. A shear pig assembly includes a main body and a nose that radially surround the linear conductor within the tubular. The main body and nose are axially moveable with respect to each other to cause a shear plug to move radially within a shearing chamber, thereby severing the linear conductor.
