The striker netted for the fifth time in the Premiership last weekend as the Jags fell just short against champions Celtic at Firhill.
Next up for the top flight newcomers is a trip to Aberdeen this evening as Thistle look to make amends for the 3-0 home defeat Derek McInnes' side dished out earlier in the campaign.
As the main man in the Firhill attack, Doolan's performances have come under the spotlight this term, with the striker on the end of criticism from some quarters when Archibald's side have failed to fire in the final third.
His double clinched victory over Inverness Caley Thistle a fortnight ago and the 26-year-old is confident there are plenty more goals to come this season.
Doolan said: "That's five goals after a quarter of the season so I am happy with that.
"I would have taken it before the start of the season.
"It is a good return of goals and it is good to be up with the top scorers in the league so I just want to keep it going.
"I have repaid the manager because he has kept faith in me and hopefully my return in goals is for him to thank him for keeping the faith in me.
"Hopefully it continues and I will continue to put the ball away for him.
"Sometimes you get criticised because I play up front myself.
"Other teams play with two strikers so others teams share that pressure and burden. I tend to get it because I play up front myself, so I am the focal point.
"Other boys will chip in with goals throughout the season but they have to, because it has to be that way. I will keep plugging away and I will get the goals."
Thistle head into tonight's Pittodrie showdown positioned eighth in the Premiership standings after an encouraging start to the campaign that has seen them go toe-to-toe with their top flight rivals.
Their tally of 13 points from 11 games should be far greater, however, with a number of wins slipping through their grasp, especially at Firhill.
Archibald's side have shown that they can more than hold their own in Scotland's highest echelon and Doolan is pleased with how the campaign has unfolded thus far.
He said: "If somebody would have told us we would have this start after a quarter of the season we would have taken your hand off for it.
"Now we are playing big games against Celtic, Aberdeen, Inverness, etc so we are delighted.
"We have not surprised ourselves as we know how good the players here are.
"We deserve to be in this position and playing in the Premier League. We have worked hard to be here and the boys deserve to have their chance."
Despite acquitting themselves well so far this term, Thistle could have found themselves further up if the standings if they had been able to convert their dominance in games into more goals.
A lack of cutting edge has cost them dear on several occasions so far but Archibald is delighted to see his main strike star finally getting the rewards his endeavours deserve as Doolan gets set to lead the line against the Dons tonight.
The Jags boss said: "I have backed Dools to the hilt. He was one of the first guys we offered a deal to at the end of last season.
"He wasn't sure if he was going to sign it or not and then when he did sign it we were delighted.
"He works ever so hard as a striker. His all-round game is very good and I am delighted for him that he has got the goals to go with it."
