Abstract
A downhole seal assembly includes a body extending from an uphole end to a downhole end. The body includes a first sealing surface and an opposing, second sealing surface that is angled relative to the first sealing surface. A first void is formed in the second sealing surface adjacent the uphole end, and a seal is arranged in the first void. A second void is formed in the second sealing surface adjacent the downhole end. One or more passages is formed in the downhole end and fluidically coupled to the second void. The one or more passages is configured and disposed to guide downhole fluids into the second void forcing the first sealing surface against a wellbore.
