Summary Volumetric maximum curvature attribute computed from 3D ocean bottom cable (OBC) seismic data, production logging tool (PLT), inorganic chemical tracer data, and fractures observed from core and full-bore formation microimager (FMI) logs were integrated to characterize fractured carbonate reservoirs of an offshore oil field in Abu Dhabi, United Arab Emirates (UAE). The extracted maximum curvature anomalies are predominantly orientated in NNE-SSW and NE-SW, a trend perpendicular to the dominant fault direction in the oil field and similar to the dominant strike directions of fractures measured from core data and FMI logs. Because the fracture strike directions of well data mimic the strike directions of curvature anomalies at corresponding reservoir levels, we interpreted the maximum curvature anomalies to represent dilatational fractured zones or fracture corridors. Integration of dynamic data, such as PLT and chemical tracers, and maximum curvature anomalies demonstrate that the inferred fracture zones can determine water breakthroughs as well as inter- and intrareservoir communications. As a result, this study highlights possible fracture zones and their internal architecture, as well as their potential flow capabilities. These results play a key role in reservoir management and monitoring of water movement through structural pathways.

阿拉伯联合酋长国阿布扎比油田 Thamama 油藏的综合裂缝表征

总结 从 3D 海底电缆 (OBC) 地震数据、生产测井工具 (PLT)、无机化学示踪剂数据以及从岩心和全孔地层显微成像仪 (FMI) 测井中观察到的裂缝计算得出的体积最大曲率属性被整合以表征裂缝碳酸盐阿拉伯联合酋长国 (UAE) 阿布扎比海上油田的储层。提取的最大曲率异常主要位于 NNE-SSW 和 NE-SW 方向，该趋势与油田的主要断层方向垂直，与岩心数据和 FMI 测井测得的裂缝的主要走向方向相似。由于井数据的裂缝走向模拟了相应储层水平曲率异常的走向，我们将最大曲率异常解释为代表扩张断裂带或断裂走廊。动态数据（例如 PLT 和化学示踪剂）和最大曲率异常的整合表明，推断的裂缝带可以确定水突破以及储层间和储层内的通信。因此，这项研究突出了可能的断裂带及其内部结构，以及它们潜在的流动能力。这些结果在水库管理和通过结构途径监测水运动方面发挥着关键作用。因此，这项研究突出了可能的断裂带及其内部结构，以及它们潜在的流动能力。这些结果在水库管理和通过结构途径监测水运动方面发挥着关键作用。因此，这项研究突出了可能的断裂带及其内部结构，以及它们潜在的流动能力。这些结果在水库管理和通过结构途径监测水运动方面发挥着关键作用。
