A NEW APPROACH FOR RESOURCE ASSESSMENT OF OIL AND GAS IN FRACTURED RESERVOIR

The authors of this Paper set up a modelling system for resource assessment of oil and gas for fracture-typed reservoir,fousing on the specialities of such a type of oil-gas pool formation.In a view of fracture system controlled occurrence of oil-gas pools,the authors predicted the number of pools in an exploratory play as well as the oil and gas reserves in each pool,based on the distributions of reserves calculated by pressure falling and the number of oil/gas pools,using ordered statistic and matched methods.Additionally,with what mentioned above,the total resources are evaluated;consequently,in an exploratory play,the potentials depending upon the amount of oil and gas in undiscovered pools are predicted.
