Abstract
A slip spool for selectively supporting a tubing string suspended in a wellbore can be mounted to a wellhead. The slip spool has an axial passage that is aligned with the wellbore, and at least two radial passages extending through a side wall of the slip spool and communicating with the axial passage. At least two slip assemblies are slidably received within the respective radial passages. Actuators move the respective slip assemblies between a retracted position in which the slip jaws clear the axial passage of the slip spool, and an extended position in which wedge-shaped slip jaws of the respective slip assemblies are inserted into an annulus between the axial passage of the slip spool to grip the tubing string.
