Patel hit an unbeaten 82 today against India 'A' and his batting has increased his chances of playing in the sub-continent, where extra spinners are essential.
"It's obviously great to get a good start in the first game and a good score - I feel great," he told ECB.co.uk.
"However there's still a lot of work to do and two games left, so I haven't got that position yet.
"I'm getting better, and the more games I play the better I'll be."
The first Test begins on November 15 in Ahmedabad.
