Hydraulic Set Single String Retrievable Production Packer

this is a new standard high performance single string  retrievable hydraulic set, shear release packer. This offers features that provide maximum pre-set prevention while running, improved sealing and retrieving reliability as well as metallurgy and elastomeric selection fit for the well environment. The simple and reliable design is compliant. There is a selective set version of hydraulic set single string packer. Setting and retrieval is essentially the same with the exception of an inner sleeve that must be shifted before the packer will set. The selective setting mechanism prevents the packer from premature setting when high tubing to annulus pressure differentials are encountered or when tubing pressure tests are performed.
