thanks for dropping by. So I am assuming you have UK citizenship. Although your GMAT is not sky high, and your GPA is on the low side your leadership is very impressive and your industry very strong, and I should hope that at the schools you listed you should have a shot. I would stay clear of mentioning the change from pharma to energy, cause it will confuse a whooooole lot of people. So I would say to strengthen your profile stick to some sort of "energy story". It'll be more plausible.
In the US I'd say the fair game schools for you are those ranked 10-40 (this under the assumption that you are a UK), The 10-20 range will be your "Dream school" range buuuuuuut you DO have this great leadership in a strong industry, so if there is one school in this range you totally love, you can think about adding it. Otherwise, for energy the two Texan schools McCombs and Jones are the strong players outside the Top 10.
Hope this helps!!!!
