Abstract
A method and apparatus to stop the influx of down hole fluids while drilling utilizing the downhole Supercharger Process including the steps of providing a down hole fluid supercharger tool in he drilling operation; detecting permeable zones at the surface while drilling utilizing the down hole supercharger process; locking the tool into a standard, continuous (non-intermittent) drilling mode; and resuming the supercharger process after the permeable zone has been penetrated. The invention also includes an method that detects permeable zones while utilizing the down hole supercharger process by monitoring pressure fluctuations at the surface, and an apparatus that controls the operation of the down hole supercharger from supercharger cycle to a conventional drilling mode by varying the compression on the tool (weight on bit).
