... Abstract Very often, a wellbore penetrates numerous geologic zones of interest. An optimum completion design addresses a method of isolating these zones while protecting the reservoir for future exploitation. A common practice is to utilize two or more packers for efficient zonal isolation...

... ABSTRACT Permian Basin operators have recently achieved improved stimulation results using precision perforation breakdown prior to their stimulation treatments. Precision breakdown of individual perforations is made possible by a recently developed hook wall straddle packer that isolates...

... In washed out holes, inflation pressures will be limited to avoid excessive pressures on the back-up sleeve ( Figure 3 ). A packer can fail by placing too high a pressure on it in a large hole. The typical failure mode, however, follows tensile failure of the metal back-up sleeve which supports...
