       the course of the study, it may be necessary to develop not only a new view of
       the reservoir, but also to prepare an explanation of why the new view is superior
       to a previously approved interpretation. If significant gaps exist in the reports,
       particularly historical performance of the  field,  it is wise to update them.

        completion  and workover data


             A review of rock and fluid property may show that the amount of available
       data is limited. If so, additional data should be obtained when possible. This may
       require  special  laboratory  tests,  depending  on  the  objectives  of  the  study. If
       measured data cannot be obtained during the scope of the study, then correlations
