Samit, who only made his England debut last month, made it to the England side, thanks to his impressive run with both bat and ball in the recently concluded ODI series against SA.
SA-born Englishman Pietersen will lead the 15-member squad studded with likes of Flintoff, Owais Shah, Collingwood.
As many as four players from Nottinghamshire - Patel, Graeme Swann, Ryan Sidebottom and Stuart Broad - feature in the England squad.
England will take on Stanford all-star side (picked by a selection panel headed by Sir Viv Richards from a pool of Carib) at St Johns Antigua and Barbuda on Nov 1.
The winners will take home a cool $20 million (a million dollar each for players).
England (Stanford T20/ODI): Kevin Pietersen (captain), James Anderson, Ian Bell, Ravi Bopara, Stuart Broad, Paul Collingwood, Alastair Cook, Andrew Flintoff, Stephen Harmison, Samit Patel, Matt Prior, Owais Shah, Graeme Swann, Ryan Sidebottom and Luke Wright.
