20 Claims

1. A method of using a reciprocating swivel in a drill or work string, the method comprising the following steps:

(a) moving a rotating and reciprocating tool toward a BOP, the tool comprising a mandrel and a sleeve, the sleeve being reciprocable relative to the mandrel and the swivel including a quick lock/quick unlock system which has locked and unlocked states;

(b) after step “a”, having the BOP close on the sleeve and then causing longitudinal movement between the sleeve and the mandrel thereby causing the quick lock/quick unlock system to enter an unlocked state;

(c) after step “b”, while the BOP is closed on the sleeve, causing relative longitudinal movement between the sleeve and the mandrel thereby causing the quick lock/quick unlock system to enter a locked state; and

(d) after step “c”, moving the rotating and reciprocating tool away from the BOP while the quick lock/quick unlock system remains in the locked state.
