Abstract
A system performs inner string cement operations in a wellbore. The system includes a stab-in stinger connected to a distal end of a drill string and a stab-in float shoe connected to a distal end of a casing. The stab-in float shoe includes a first check valve and a plug type rupture disc. The first check valve includes instructions configured to prevent a reverse flow of cement mixture. The plug type rupture disc is house between the first check valve and an outlet of the stab-in float shoe. The plug type rupture disc includes instructions configured to rupture at a predetermined threshold pressure and, once ruptured, permits flow of cement mixture from the annulus into the stab-in float shoe. A related method includes: enabling a stab-in stinger to stab-into a stab-in float shoe, starting the cementing operation and rupturing the plug-pe rupture discs at predetermined pressure.
