Abstract

The Boost Bump is a geometric entity of added material that reinforces the O Seal allowing much higher contact force with the ID of the casing while keeping the strains on retrieval of the O Seal essentially the same.

The Boost Bump is a geometric entity of added material that reinforces the O Seal allowing much higher contact force with the ID of the casing while keeping the strains on retrieval of the O Seal essentially the same.

The Boost Bump is a concentric protuberance on the dynamic side of the O Seal which helps support the O Seal in setting. As the O Seal makes contact with the casing during setting, the friction of the casing causes the O Seal to roll back towards the dynamic side where the Boost Bump comes into contact with the dynamic gauge ring and continues the driving movement towards the static side. This driving reinforcement by the Boost Bump doubles the contact length with the casing ultimately facilitating a better seal. The part of the O Seal that deforms over the static gauge ring, deforms substantially more resulting in more stability on the static side also. Overall, FEA has shown that this increases the contact force with the casing by up to 160 percent more for the same material while keeping strains upon retrieval essentially the same. This allows the customer to use a cheaper material while still attaining comparable contact forces with the casing
