Abstract
Apparatus and method is disclosed for setting inflatable packers in a well bore which includes the transporting of settable fluid from the surface with a work string or liner as it is run in the well. The invention therefore negates the requirement of having to pump cement or the like to precise locations down hole to the vicinity of the packers to be set.
