This study extends an integrated field characterization in Eagle Ford by optimizing the numerical reservoir simulation of highly representative complex fractured systems through embedded discrete fracture modeling (EDFM). The bottom-hole flowing pressure was history-matched and the field production was forecasted after screening complex fracture scenarios with more than 100 000 fracture planes based on their propped-type. This work provided a greater understanding of the impact of complex-fractures proppant efficiency on the production. After compaction tables were included for each propped-type fracture group, the estimated pressure depletion showed that the effective drainage area can be smaller than the complex fracture network if modeled and screened by the EDFM method rather than unstructured gridding technique. The essential novel value of this work is the capability to couple EDFM with third-party fracture propagation simulation automatically, considering proppant intensity variation along the complex fractured systems. Thus, this work is pioneer to model complex fracture propagation and well interference accurately from fracture diagnostics and pseudo 3D fracture propagation outcomes for multiple full wellbores to capture well completion effectiveness after myriads of sharper field simulation cases with EDFM.

本研究通过嵌入式离散裂缝建模 (EDFM) 优化具有高度代表性的复杂裂缝系统的数值储层模拟，从而扩展了 Eagle Ford 的综合油田表征。在根据支撑类型筛选具有超过 100 000 个裂缝平面的复杂裂缝场景后，井底流动压力与历史匹配，并预测了油田产量。这项工作使人们对复杂裂缝支撑剂效率对生产的影响有了更深入的了解。将每个支撑型裂缝组的压实表包括在内后，估计的压力损耗表明，如果通过 EDFM 方法而不是非结构化网格技术进行建模和筛选，有效泄流面积可以小于复杂的裂缝网络。这项工作的基本新颖价值是能够将 EDFM 与第三方裂缝扩展模拟自动耦合，同时考虑到支撑剂强度沿复杂裂缝系统的变化。因此，这项工作是从多个全井眼的裂缝诊断和伪 3D 裂缝扩展结果准确模拟复杂裂缝扩展和井干扰的先驱，以在使用 EDFM 进行无数更清晰的现场模拟案例后捕获完井效果。
