Abstract
(EN)
An energizing ring (200, 400, 600) for setting a downhole seal (300, 500) includes a body having a varied cross-section along at least a portion of an axial length (204, 418, 604). The energizing ring also includes a plurality of peaks (216, 410, 612) forming at least a portion of the varied cross-section having a first diameter (218 A, 414) and a plurality of valleys (222, 412, 616) forming at least a portion of the varied cross-section having a second diameter (416), the first diameter (218 A, 414) being larger than the second diameter (416), and respective valleys (222, 412, 616) of the plurality of valleys (222, 412, 616) being arranged proximate respective peaks (216, 410, 612) of the plurality of peaks (216, 410, 612).
