APPARATUS AND METHODS FOR STIMULATING A SUBTERRANEAN WELL

摘要

A method of stimulating a subterranean well permits each desired location within a portion of a well to be isolated from other portions of th e 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 t he fluid, and flowing stimulation fluids through the opening and into a formati on surrounding the portion of the well.
