Abstract
A non-ballistic tubular perforating system includes a tubular having a wall with perforations therethrough and at least one radially extendable member positioned radially of the perforations configured to displace cement radially of the tubular and configured to radially extend prior to pumping of the cement.
Claims24
A non-ballistic tubular perforating system comprising:
- a tubular having a wall with perforations therethrough;
- and
- at least one radially extendable member positioned radially of the perforations configured to displace cement radially of the tubular and configured to radially extend prior to the cement being pumped.
A method of opening perforations in a tubular system comprising:
- radially increasing a radially increasable member positioned radially outwardly of perforations in a tubular positioned within a borehole in an earth formation;
- cementing an annular space between the tubular and the borehole;
- displacing cement with the radial increasing of the radially increasable member;
- pumping fluid through the tubular;
- and
- breaching the radially increasable member and establishing fluidic communication between an inside of the tubular and the earth formation.
3 more elements
A non-ballistic tubular perforating system comprising:
- a tubular having a wall with perforations therethrough;
- at least one radially extendable member oriented radially of the tubular proximate the perforations configured to prevent cement from being positioned radially of the perforations when in a radially extended condition;
- and
- at least one occluding member configured to initially prevent fluid inside the tubular from reaching the radially extendable member.
