Push Reaming

Last updated: May 8, 2017

What Does Push Reaming Mean?

Push reaming is a technique to resolve the issue of preventing drilling fluid from ending up in the exit recovery pit during the reaming process. In this technique, the bottom hole assembly is removed from the exit site to the drill pipe and a swivel is then attached to the pipe. The swivel is then attached to a "pulling machine." The pulling machine could be a winch, backhoe, track hoe or a crawler tractor. In trenchless construction, push reaming is an important aspect of mud recovery and cleanup.

Also termed forward reaming.

Trenchlesspedia Explains Push Reaming

The importance of push reaming is revealed in the economics of the process outcomes in terms of gaining the ability to process and reuse drilling fluid. The push reaming technique also prevents mud returns from backing to the entry and recovery pit and is an efficient means of avoiding fluid buildup in the bore hole. It must be noted that not all boring equipment is able to work with the bi-directional nature of this method. The cutters and the core of an auger, or reamer, must be able to work in a manner consistent with bi-directional rotation.
