Double Inflatable Packer

Also know as Straddle Packer System, are used for hydraulic fracturing tests to measure in-situ stress in rocks. It enables the isolation of two zones using a single-packer system and allows the investigation of two zones with a single trip into the well with the downhole tools. The isolation created between the two zones also enables independent investigation of each zone. These packers are also used in well-completion work to shut off zones.
