The Oilenco OneDrift is a simple, yet effective solution to well bore drifting. The OneDrift is run into the well on wireline, tractor or coiled tubing.

When the tool encounters a restriction within the well, jar action or downward force is applied until the restriction has been passed. This reduces the tools outer diameter in 0.100” increments, allowing access beyond the restriction. The same process is applied to overcome further restrictions within the wellbore, allowing the target depth to be achieved in a single run. Upon tool retrieval the drift diameter is measured to verify the minimum well bore restriction.

For unknown restrictions, i.e. scale deposits, collapsed tubing, etc., the tool will operate in the same manner. There is no correlation between the number of jar impacts applied to activate the tool, it will simply continue to reduce in diameter until the restriction has been passed.

As the outer diameter is adjusted during the run, the drift diameter is measured to verify the minimum wellbore restriction upon tool retrieval.
