Abstract
A cement masking system includes a tubular having a wall with at least one radial port. At least one swellable member is arranged to cover the at least one port. The at least one swellable member is configured to at least partially displace cement radially of the tubular during radial expansion of the at least one swellable member. A method of masking ports in a tubular from cement employs the cement masking system.
