Abstract
A downhole system including a tubular having a wall with at least one port there through. At least one member arranged to cover the at least one port in a compressed condition thereof. Configured to at least partially displace cement pumped on an exterior of the tubular in a radially expanded condition of the at least one member. Also included is a method of non-ballistically opening ports in a tubular of a downhole system.

A downhole system comprising:
- a tubular having a wall with at least one port there through;
- and
- at least one member arranged to cover the at least one port in a compressed condition thereof, and configured to at least partially displace cement pumped on an exterior of the tubular in a radially expanded condition of the at least one member.
A method of non-ballistically opening ports in a tubular of a downhole system, the method comprising:
- covering at least one port in the tubular with an initially compressed radially extendable member;
- inserting the tubular within a borehole;
- cementing an annular space between the tubular and the borehole;
- allowing the radially extendable member to expand from heat of curing cement;
- and,
- at least partially displacing the cement with the radially extendable member.
