Claim 9:
10. A method for running a tubular, comprising:
suspending a mandrel above a wellbore,
the mandrel having an elongated body with a longitudinal axis, an upper end and a stem portion at an end opposite the upper end, a plurality of stepped ramps on a surface thereof near a tip of the stem portion, a plurality of superior ramps on a surface thereof near the upper end, and a plurality of slips disposed on the mandrel,
each slip having an upper end, a lower end, and a stem portion in between the ends, a plurality of stepped ramps near the lower end of the slip configured for complementary engagement with the plurality of stepped ramps near the tip of the mandrel stem portion, each slip having a stepped ramp near the upper end of the slip configured for complementary engagement with a superior ramp near the upper end of the mandrel, and each slip configured to receive and retain an insert having a gripping portion on a surface thereof;
disposing a section of the mandrel into a tubular;
actuating the mandrel to engage the stepped ramps and superior ramps thereon with the respective stepped ramps on each slip for actuation of the slips between a neutral position and an extended position,
wherein upon actuation of the slips between the neutral position and the extended position the slips and the inserts disposed thereon remain parallel to the longitudinal axis of the mandrel;
actuating the mandrel to urge the slips radially outward such that the inserts disposed on the slips are correspondingly urged radially outward to engage the inner surface of the tubular;
manipulating the tubular with the mandrel;
and
actuating the mandrel at a desired location to retract the slips to disengage the inserts from an inner surface of the tubular to release the tubular.
