ABSTRACT:
This specification discloses a method of controlling an active zone that is penetrated in the drilling of a well. In accordance with the method there is formed a mixture of inert particulate material and an oil-wetting dispersing agent in a light oil and the mixture is circulated to a lower portion of the well and maintained there to allow the inert particulate material to separate from the light oil and form a plug in the well to control the active zone.
