RESERVE ESTIMATION

RESERVE ESTIMATION & CALCULATIONS

a)Proven and drilled structures

                           -Oil reserve in place
                           -Recoverable oil reserve
                           -Gas reserve in place
                           -Recoverable gas reserve

  b)Undrilled structure

                           -Area
                           -Estimated oil in place
                           -Estimated recoverable oil

c)Evaluation of recovery Factors(RF)

                           -Influence of lithology(limestone,dolomite,sandstone)
                           -Influence of porosity-permeability
                           -Influence of fractures
                           -Influence of oil characteristics(Light oil, heavy oil, GOR)
                           -Influence of pressure and temperature
                           -Historical production data evaluations
