Study on the Operational Risk Assessment Model of Untapped Low-grade Reservoirs

First of all, by defining low-grade reservoir in this paper, we evaluate and quantitatively analyze operational risks of the untapped low-grade reservoir and classify the operational risks. Then, through introducing the probability analysis method and combining with the low-grade reservoir operation, we establish the operational risk assessment model of the untapped low-grade reservoir. Finally, by using the mathematical software MATLAB to calculate all kinds of relevant graphics and tables, we evaluate and quantitatively analyze the operational risks of the low-grade reservoir.
