Abstract (en)

A method of stimulating a portion of a subterranean well (12) at axially spaced apart desired stimulation locations therein, the well portion intersecting a formation (38), comprising: disposing a viscous fluid (32) within the well portion; forming an opening (56) through the viscous fluid (32) at a first one of the desired stimulation locations; and flowing stimulation fluids through the opening and into the formation (38) at the first desired stimulation location, whereby the viscous fluid (32) substantially prevents flow of the stimulation fluids into any portion of the formation (38) other than at the first desired stimulation location. <IMAGE>
