The first leg of the trip is coming out of the hole, by lifting the entire drill string and unscrewing the upper most drill pipe called a joint, the newly removed drill pipe is laid beside the rig and the drill string is lifted again, etc. until all drill pipe is out of the hole. After service work is performed, for example change to fresh drill bit, then the second leg of the trip is to reverse the process, lowering the drill string as each new joint is made until fully back in the hole with the bit on bottom.
