                              TRANSPORTATION

                A  motivated,  multinational  workforce  has  achieved
           extraordinary gains in drilling efficiencies by using highly mobile
           drilling  rigs  (Fig.  18.1)  to  deal  with  tough  desert  and  geologic
           conditions.
