A packer having a swellable element is configured for axial expansion of the swellable element. The axial expansion causes the slip mechanism to deploy and engage a sidewall of a tubular or casing. The axial expansion may directly cause activation of the slip mechanism, or may trigger a triggering mechanism to activate a spring-loaded slip mechanism. The swellable element may be the same element used for sealing the packer to the sidewall, or may be a sleeve dedicated for deployment of the slip mechanism.
