Cased Hole: Pressure Operated

A Fullbore Pressure Operated Tool configuration is most often used when a job requires Tubing Conveyed Perforation (TCP) or in situations where hole conditions are not conducive to setting packers in open hole sections. This DST method is capable of testing the entire interval below the packer, while all the tools remain in the casing. This means that large sections of perforations and open hole intervals can be tested at the same time.
