What are my chances of getting into UT Austin into petroleum engineering?

ACT 31C 30E 35M 31R 28S
4.0 GPA
Top 13% of high school class rank (it is really competitive, I get high A’s in AP classes but still not in top 10%)
Taking 3 AP classes this year and 2 dual credit
Texas High School
Class of 2017

I am trying to decide whether or not to retake the ACT or just use the scores I have now, what do y’all think my chances would be of getting into petroleum engineering at UT if I just stuck with these scores?
