A preliminary study of the $e^+e^- \rightarrow b\overline{b}$ process
at centre-of-mass energies up to 208 GeV is presented. High energy events,
with an effective centre-of-mass energy $\sqrt{s^{\prime}/s} > 0.85$, are used.
Decay-tag methods and semileptonic decays of b quarks are used
to select bbbar events and to study their production characteristics 
above the Z pole.
