Doran is joint top of the Clydesdale Bank Premier League assists list alongside Motherwell striker Henrik Ojamaa with 12, while Raven has proved a successful summer signing at right-back.
Butcher, whose side host St Johnstone on Friday night, said: "We are speaking to their agents and getting on very well. I'm optimistic that we can get something done. That might not be until next week possibly.
"But they are good boys and it's nice when players see their colleagues and friends pen two-year deals to stay here.
"If we can get two or three of these boys signed up that will mean we have got the nucleus of the squad again for next season.
"If David Raven signs we have got the same back four again, which is a first. It's good because it shows to us they have got a lot of faith in the club and what we're doing."
Doran revealed he was keen to conclude a deal following talks with Butcher.
The Irish winger said: "I'd be delighted. We spoke last week and I told him to get in contact with my representatives and we can take it from there. "There have been some discussions this week and hopefully it will be good news.
"We have got something special here. This team spirit is the best I've ever see. The gaffer has nearly signed everyone up from this team.
"I don't know why anyone would want to leave. We are doing really well and could be playing in Europe next season."
