Compare uniformtarianism. catcher n: a device fitted into a junk basket that retains the junk picked up by the basket catch samples v: to obtain cuttings for geological information as formations are penetrated by the bit The samples are obtained from drilling fluid as it emerges from the wellbore or, in cable-tool drilling, from the bailer. Cuttings are carefully washed until they are free of foreign matter, dried, and labelled to indicate the depth at which they were obtained.

n: a special tool made up on the bottom of the drill stem to pick up junk from the bottom of the hole. Most junk retrievers are designed with ports that allow drilling fluid to exit the tool a short distance off the bottom. This flow of fluid creates an area of low pressure inside the tool so that the junk is lifted and caught in the retriever by the higher pressure outside the tool. See junk, junk basket.

n: see finger-type junk basket.
