15. A method for latching to a mating mandrel, comprising:
running a resettable latch assembly into the mating mandrel positioned in a borehole, wherein the resettable latch assembly comprises an energy transfer line;
engaging a collet engagement surface of the resettable latch assembly with a mating engagement surface of the mating mandrel to latch to resettable latch assembly in the mating mandrel;
disengaging the resettable latch assembly from the mating mandrel by moving the resettable latch assembly uphole without rotation;
moving the resettable latch assembly downhole to reengage the collet engagement surface of the resettable latch assembly with the mating engagement surface of the mating mandrel to latch the resettable latch assembly in the mating mandrel;
coupling the energy transfer line to a downhole energy transfer line; and
supporting fingers of the latch mandrel at the collet engagement surface to lock the latch mandrel on the mating mandrel, wherein:
moving the resettable latch assembly downhole to reengage the collet engagement surface of the resettable latch assembly with the mating engagement surface further comprises landing a lower mandrel of the resettable latch assembly in the mating mandrel to limit downward movement of the resettable latch assembly; and
then applying additional downward force to the resettable latch assembly such that upper shear members holding the lower mandrel to an upper mandrel of the resettable latch assembly are sheared.
