Abstract:
1. A method to stop the upward influx of down hole fluid from down hole during a down hole drilling operation utilizing a supercharger process, whereby permeable zones are detected as soon as they are penetrated during the drilling operation, and whereby a downhole fluid supercharger tool that detects permeable zones while utilizing the down hole supercharger process by monitoring pressure fluctuations at the surface is actuated into the drilling cycle immediately, the method comprising the following steps: a. providing the down hole fluid supercharger tool in the drilling operation; b. detecting permeable zones at the surface while drilling, utilizing the down hole supercharger process; c. locking the down hole fluid supercharger tool into a standard drilling cycle to interrupt the supercharger process; and d. resuming the supercharger process.
