Figure  3.10  -  Dynamic  basic  indicators  of  development
          under water drive

                  Under  water  drive,  oil  production  accompanied  by  its
          replacement  water,  which  explains  the  stable  value  over  time
          flowrates of wells, formation pressure and gas oil ratio.



                    §3.2 MAIN HYDRODYNAMIC CALCULATIONS
                       UNDER ELASTIC-WATER DRIVE

                  Condition  of  elastic-water  drive  -  excess  formation
          pressure above the saturation pressure. The drive appears in early
          development and is characterized in descending reservoir pressure.
          In  solving  elastic-water  drive  the  important  task  is  to  develop  a
          definition of conversion put the solution gas drive. Knowledge of
