Abstract
A perforating gun, adapted to be disposed in a deviated borehole, includes an intra-gun swivel located between a first plurality of charges and a second plurality of charges of the perforating gun. The swivel includes a first housing, a second housing, and thrust and radial bearings disposed between the surfaces of the first and second housing for allowing the first housing to rotate with respect to the second housing and therefore the first plurality of charges to rotate with respect to the second plurality of charges of the perforating gun.
