Question on big oil hearings

I gather that there were hearings in the past few days with big oil company executives testifying before Congress...
I heard bits and pieces on the radio, and I heard questions pertaining to the price of a barrel of oil. Why is it so high? asked the Committee...Mr. Shell, and Mr. Chevron etc. had various answers. It is the demand...it is the rising costs of this and that...speculation...bla, bla and bla.

But tell me, did they ask questions not about the barrel of crude, but about the HUGE PROFITS. Mr. Shell, if the barrel of crude costs more, and if refining costs have gone up, how come your profit this year is higher than any profit of any company since the beginning of time????

Did anyone ask that question????
The logical equation is costs go up, price goes up to cover the cost, and the profit remains the same...How can it be that costs go up, price goes up, and profit shoots up into the stratosphere?????Will you tell us Mr.Shell?
