What does fuel oil equivalent @barrel (US) mean?

It represents the energy contained in one U.S. barrel of fuel oil, used to express petroleum volumes on an energy basis rather than just volume.

Why use calorie (IT) instead of joules?

Calorie (IT) is a historical unit important for interpreting legacy thermodynamic data and steam-engine calculations, though it is largely replaced by joules today.

Is this conversion exact for all fuel oils?

No, the exact energy content varies by fuel grade and density, so the conversion should be considered approximate.
