Abstract

A pump down device is deployed at an anchor point in a pipe to perform a pipe severing operation. The pump down device includes: a cutting head positioned at one end of the pump down device that severs the pipe; one or more centralizers that are positioned adjacent to the cutting head and configured to provide friction for deployment of the pump down device at the anchor point and centralize the cutting head; a seal that is positioned near an end opposite to the one end of the pump down device; and an electronics housing that includes a plurality of electronic sensors. The pump down device releases an anchor mechanism upon reaching the anchor point as determined by the plurality of electronic sensors based on preprogrammed inputs. The seal prevents fluid from moving past the pump down device when in operation.
