Description:The present invention related to “Replacement of Check Valve by Valvular Conduit in Float Shoe”
A Float Shoe is a critical component used in the casing string of an oil and gas well. It is installed near the bottom of the casing string and serves multiple functions during cementing operations. The conventional Float Shoe contains a one-way check valve that prevents cement slurry from flowing back into the casing after it has been pumped into the annulus. By replacing the check valve with valvular conduit, it will eliminate the dependency on moving parts of check valve during cementing operation and by basic nature of valvular conduit it will eliminate the u-tube possibility or minimize it to very miniscule levels. Float Shoes with inbuilt valvular conduit can be deployed in oil/gas well for cementing operation. Valvular Conduit acts as a passive check Valve/Non-Return Valve. It also has no moving parts. Thus, with the usage of valvular conduit all problems associated with the current conventional design will , Claims:Accordingly the present invention Replacement of Check Valve by Valvular Conduit in Float Shoe comprises:
1. Invented Replacement of Check Valve by Valvular Conduit in Float Shoe completely eliminates the problems associated with current conventional Float Shoes.
2. Invented replacement of Check Valve by Valvular Conduit in Float Shoe as claimed in claim 1 where the valvular conduit does not contain moving parts and thus it does not get jammed inside the well.
