1. A swivel connection tool for use in connecting or disconnecting a tubular of a work string or drill string to a swivel suspended over an elevated work floor of a derrick, the swivel connection tool comprising:
- a yoke having a bore therethrough and an opening from a perimeter of the yoke to the bore, the opening sized to receive the tubular through the opening and the bore sized to receive the tubular;
jaws carried by the yoke and movable with respect to the bore between an open position further from the bore to a tight position closer to the bore configured to hold the tubular in the bore and resist rotation of the tubular in the bore;
an actuator carried by the yoke and operatively coupled to the jaws to move the jaws between the open position and the tight position;
a base carrying the yoke and configured to be carried by the work floor; and
the yoke being oriented at an incline on the base with a bore axis oriented at an acute angle with respect to horizontal.

19. A swivel connection tool used for connecting a swivel to a tubular, the swivel connection tool comprising:
-
a yoke having a bore therethrough and an opening from a perimeter of the yoke to the bore, the opening sized to receive the tubular through the opening and the bore sized to receive the tubular; jaws carried by the yoke and movable with respect to the bore between a an open position further from the bore to a tight position closer to the bore configured to hold the tubular in the bore and resist rotation of the tubular in the bore; an actuator carried by the yoke and operatively coupled to the jaws to move the jaws between the open position and the tight position; a base carrying the yoke and configured to be carried by a work floor; the yoke being oriented at an incline on the base with a bore axis oriented at an acute angle with respect to horizontal; an arm coupled between the base and the yoke; a vertical slot in the base receiving the arm therein; a horizontal slot in the base transverse to the vertical slot; a pin extending through the horizontal slot, the vertical slot, and the arm; the pin displacing in the horizontal slot to allow heave movement of the arm and the yoke towards and away from the base; the arm and the yoke pivoting about the pin to allow pitch movement of the arm and the yoke tilting forward and backward with respect to the base; and the arm and the yoke being capable of roll movement with the arm and the yoke tilting side to side with respect to the base.

20. A swivel connection tool in combination with a work floor, the combination comprising:
-
the work floor capable of being elevated with respect to a support surface and having an opening locatable over a wellhead; a base locatable on the work floor with the base attached to the work floor; a yoke carried by the base and having a bore therethrough and an opening from a perimeter of the yoke to the bore configured to receive a tubular through the opening into the bore; jaws carried by the yoke and movable with respect to the bore between a an open position further from the bore to a tight position closer to the bore configured to hold the tubular in the bore and resist rotation of the tubular in the bore; an actuator carried by the yoke and operatively coupled to the jaws to move the jaws between the open position and the tight position; the yoke having a bore axis oriented at an acute incline with respect to horizontal and the work floor; and the base of the swivel connection tool located in a fixed position spaced-apart from the opening in the work floor.
