Abstract
A method for installing and operating a cable head with cable shear mechanism for wireline cable supporting oilfield equipment in a wellbore. The cable head has a housing, a cable bore, a tapered sleeve, a sliding bell, a drive pinch cylinder, a linear biasing mechanism positioned between the tapered sleeve and the drive pinch cylinder, a plurality of shear pins disposed partially into the housing and though the drive pinch cylinder, wherein each shear pin is adapted to withstand from 100 pounds to 2000 pounds of shear load, a pair of slidable cutting segments, and a pair of slidable cutting segment guides. When cable load exceeds a preset limit, the shear pins shear allowing the slidable cutting segments to be moved up the slidable cutting segment guides to impact and shear the cable.
