Joey O'Brien's strike two minutes into the second period cancelled out Jonathan Walters' first-half strike, but try as they might they could not get that elusive winner which would have seen them go to fifth.
"We were unlucky in the end and we had enough chances," Nolan told Sky Sports 1.
"It is a great result after going 1-0 down and these lads they make it tough for you, they played well tonight. I thought we did, we were unlucky, we were a bit gutted because we wanted to get the win to go to fifth."
It was O'Brien's first Premier League goal and Nolan was keen to praise the full-back who joined from Bolton two years ago.
"He had a tough two years out with a bad knee injury," the captain said. "The way he has come back in the last two years for us. Last year he was fantastic and this year he has been even better, he is getting stronger and stronger.
"All the lads have a great camaraderie we were delighted for him. They are a tough nut to crack."
