ORDERING THE EXPLOITATION OF HETEROGENEOUS CARBONATE GAS RESERVOIRS
SINOPSIS
Conventionally integrated exploitation cannot be widely applied in carbonate gas reservoirs because of the heterogeneous space and pressure compartmentalization. Complex geological characteristics cause irregular production and uncertain investment. This paper develops an approach for optimization of the exploitation sequence that aims to maximize the total benefits of heterogeneous carbonate gas reservoirs within the constraints of their physical characteristics. We quantify the relationships among exploitation proportion, production rate, length of the stable production period, and costs. A carbonate gas field is illustrated as an example, in which the optimal exploitation sequence is calculated within its own physical constraints. Sensitivity analysis is introduced to present the impacts of uncertainty factors on the optimal proportion. The results show that the length of the extended stable period has a negative impact, while the gas price and discount rate have no impacts, and the optimal proportion is more sensitive to shortening of the stable periods. Meanwhile, the sliding scale linked to the income tax rate indeed has an impact on the optimal proportion, but the changed drilling mode has no impact. This study is important in that it helps companies make development strategies and optimize investments of surface facilities for heterogeneous carbonate gas reservoirs.
