Number of net wells drilled annually |

|
| |
The following
tables show the net productive and dry exploratory and development oil and
gas wells completed or abandoned by the
Group
from 2000 to 2005. Productive wells include wells in which hydrocarbons were
found, and the drilling or completion of which,
in
the case of exploratory wells, has been suspended pending drilling or
evaluation. A dry well is one found to be incapable of
producing in
sufficient quantities to justify completion. |
