HoleGuard™ Wellbore, Hanger and Seal Area Protector
Protecting exposed wellbores, hangers and seal areas during Well Intervention.
Page last modified
June 24 2024
During well intervention, where the wellbore, hanger and flange seal areas are exposed, there is a risk that a dropped object may enter the wellbore or damage the hanger or seal area, leading to lost production and increased well costs. To reduce this risk A.L.A.R.P Operators collaborated with ThinJack® to develop HoleGuard™ for platform or land based surface wells.
With tie down straps, if you want to use them, HoleGuard creates a rigidly contained, near immovable, air gap between the inside of its cylinder and the hanger neck. This reduces the likelihood of dropping objects into the well bore causing damage to safety valves and gas lift mandrels, or obstructions to choke valves. Removing these dropped objects may need costly multi-trip fishing operations .
HoleGuard gives operators confidence that wellbores, hangers and critical sealing parts are better protected than they would be otherwise.
