Along with conventional methods, this paper proposed a method in which 1D and 3D models are integrated to identify the self-sourced reservoir potential of the Farewell Formation in the Kupe Gas Field within the Taranaki Basin, New Zealand. Source rock characteristics were evaluated at both field and basin scales by investigating source rock maturity, type of organic matter, and hydrocarbon generation potential by rock pyrolysis, using Rock-Eval 2 and 6. The 1D thermal and burial history model established the rate of sedimentation and thermal history of the Kupe 4 well. Reservoir characterization at field-scale was determined by seismic interpretation, well log analysis, and 3D structural and petrophysical models. The sediments of the Farewell Formation contain types II–III (oil/gas prone) and type III (gas prone) and have fair-to-excellent generation potential. The oxygen and hydrogen indices ranged from 3 to 476 mg CO₂/g TOC and 26 to 356 mg HC/g TOC, respectively, whereas the thermal maturity determined by vitrinite reflectance values ranged between 0.3% and 0.72%, indicating that the Farewell Formation is in immature-to-mature hydrocarbon generation stage. Thus, Farewell Formation was verified to be a good source rock. Additionally, structural interpretations demonstrated the structural complexity of an extensional and contractional regime within the reservoir package. Multiple faults indicated a good reservoir property there with a trapping mechanism as well as migration paths. A well-log-based petrophysical analysis established the presence of up to 70% hydrocarbon saturation within the pore spaces of Farewell sandstones. The 3D models confirmed that the Farewell Formation has significant sand zones and hydrocarbon-saturated zones, thereby proving its very good reservoir characteristics. It has been proved that the 1D and 3D structural schemes, integrated with geological techniques, was vital in identifying the Kupe Field as a self-sourced reservoir.

与常规方法一起，本文提出了一种方法，其中将一维和3D模型集成在一起，以识别新西兰塔拉纳基盆地内库佩气田的告别地层的自采储层潜力。通过使用Rock-Eval 2和6研究岩石热解过程中的烃源岩成熟度，有机质类型和生烃潜力，在野外和盆地尺度上对烃源岩特征进行了评估。一维热和埋藏历史模型确定了沉积速率和Kupe 4井的热历史。通过地震解释，测井分析以及3D结构和岩石物理模型确定了油田规模的储层特征。告别组的沉积物包含II–III型（油气倾向）和III型（油气倾向），并且具有相当好的生成潜力。氧气和氢气指数范围为3至476 mg CO₂ / g TOC和26至356 mg HC / g TOC分别由镜质体反射率值确定的热成熟度介于0.3％和0.72％之间，这表明告别组处于未成熟到成熟的烃生成阶段。因此，告别组被证明是一种良好的烃源岩。另外，结构解释证明了储层组内伸展和收缩状态的结构复杂性。多个断层表明那里具有良好的储集层性质，并具有圈闭机制和运移路径。基于测井曲线的岩石物理分析确定了告别砂岩孔隙内存在高达70％的烃饱和度。3D模型证实了告别层具有明显的砂带和烃饱和带，从而证明了其非常好的储层特征。
