Injury and form has restricted Abraham to just 127 minutes of football since Carvalhal arrived at the Liberty Stadium, but the Chelsea loanee will be given regular action for the rest of the campaign.
The 52-year-old is quoted as saying by the club's official website: "Tammy Abraham is an interesting player. Wilfried's injury will give more opportunities to him and he is someone we believe in a lot.
"We liked him last season when he was scoring a lot of goals in the Championship. He has quality, a lot of pace and he is a good finisher.
"He is a very good talent and we will try to help him give the maximum to the team."
Abraham has contributed four goals and one assist in 20 Premier League appearances this season.
