ABSTRACT:
A method of stimulating a subterranean well permits each desired location within a portion of a well to be isolated from other portions of the well during stimulation operations therein, but does not require lining a portion of the well with casing and cement, and does not require the use of sealing devices, such as inflatable packers, in the well portion. In a preferred embodiment, a stimulation method includes the steps of depositing a barrier fluid in a portion of a well, forming a radially extending opening through the fluid, and flowing stimulation fluids through the opening and into a formation surrounding the portion of the well.
