Economic evaluation of development and sensitivity analysis

Economic feasibility analysis is made for the development of the outstep wells in the peripheral fields by means of technical and economic principle and the critical economic flow rate of the single well in the peripheral well zones; the economic limit values are established and the basic evaluation indicators are calculated. Results show that three of the fields satisfy the conditions for development, and two of the fields do not. Three factors, sale prices, investment and operation cost, are selected for the sensitivity analysis. Results show that sale prices and operation cost have bigger effect on the internal benefit indicators.
