The PetroQuip Locking Bridge Plug (LBP) is a selective lock designed for the high heat of geothermal wells. Utilizing PetroQuip’s high temperature chevron packing this LBP can take temperatures up to 600⁰F and pressures up to 7000 psi. The selective running tool allows as many plugs of the same size to be run in the same wellbore. The plug is designed to be retrieved only leaving the large bore profile nipples in the casing.
