1. A method comprising:
providing one or more preconfigured drill pipe segments including:
a quantity of lost circulation material objects disposed therewithin; and
a dissolvable retention element that retains the lost circulation material objects within the one or more preconfigured drill pipe segments;
connecting the one or more preconfigured drill pipe segments to a drill string at a wellbore; and
flowing drilling fluid through the one or more preconfigured drill pipe segments;
wherein the flowing of drilling fluid through the one or more preconfigured drill pipe segments causes the dissolvable retention element to structurally disintegrate and thereby release the lost circulation material objects to propagate further.
