The Portugal international will hope to impress this week.
The Portuguese international arrived until the end of the season after previously difficult stints with Swansea and Rennes.
He has struggled to find the net regularly for Forest although he did recently score the winning goal against Derby County in the East Midlands derby - which has already assured him of some memorable status among the Forest faithful.
He is currently away with the Portuguese national side for their upcoming friendly matches with Russia and Luxembourg - with star striker Cristiano Ronaldo missing.
This could hand a chance to Oliveira - who is hopeful of making it into the squad ahead of the European Championships next summer.
Oliveira told Correio da Manha this week:
"I want to go to the Euros. The coach is under observation phase and I want to enjoy it. Now I have a good opportunity to demonstrate my value.
"I knew it would be difficult, but I tried to work well to deserve to be here."
Of course he will also need to up his accuracy for Forest. He has only scored twice for the club and has a fairly poor strike rate. The club in general are shy of goals and if he can pick up his tally then Forest will climb up the Championship table - and it wouldn't do his international chances any harm.
