Abstract
A cement masking system including a tubular having a wall with at least one radial port. At least one swellable member arranged to cover the at least one port. The at least one swellable member configured to at least partially displace cement radially of the tubular during radial expansion of the at least one swellable member. Also included in a method of masking ports in a tubular from cement,
Claims23
A cement masking system comprising:
- a tubular having a wall with at least one radial port;
- at least one swellable member arranged to cover the at least one port, the at least one swellable member 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, the method comprising:
- covering the ports by at least one swellable member;
- inserting the tubular within a borehole;
- cementing an annular space between the tubular and the borehole;
- allowing the swellable member to expand from liquid;
- and,
- at least partially displacing the cement with the swellable member.

A cement masking system comprising:
- a tubular having a wall with at least one radial port;
- at least one radially extendable member arranged to cover the at least one port, the at least one radially extendable member configured to at least partially displace cement radially of the tubular during radial expansion of the at least one radially extendable member;
- and,
- at least one shunt tube configured to allow passage of cement past the at least one radially extendable member.
