The Khalda Concession is located southeast of the Abu Gharadig Basin in the Western Egyptian Desert. The present study is based on Rock-Eval pyrolysis and vitrinite reflectance (%Ro) data of the SPYGLASS-1X and AG-24 wells and analyses of two-dimensional seismic sections. This study evaluates the hydrocarbon potential, quality of organic matter, and thermal maturation history of the Abu Roash F and G members and the Bahariya Formation in the two wells. In addition, two burial history models were constructed using the PetroMod software to determine the status of the studied sequences with respect to oil and gas windows and the timing of hydrocarbon generation, which depend on the modeled %Ro. The structural setting and entrapment styles of the generated hydrocarbons were detected via the interpretation of the two-dimensional seismic lines using the Petrel software platform. The results indicate that the hydrocarbon potentiality of the Bahariya Formation and the Abu Roash F and G members ranges from poor to very good with the total organic carbon reaching 2.5 wt%. The hydrogen index values indicate that the kerogen types are mainly Type II, mixed Type II/III, and Type III. In addition, the maturity parameters (%Ro, T_max, and the production index) and the burial history models of the studied wells indicate that the Abu Roash F and G members and the Bahariya Formation have reached the mature stage at the studied depths. The seismic interpretation reveals that the entrapment styles of the generated hydrocarbons are primarily structural traps of normal faults, forming horst and graben structures, and anticline folds.

哈尔达租界位于埃及西部沙漠的阿布加拉迪格盆地东南部。本研究基于SPYGLASS-1X 和 AG-24 井的Rock-Eval 热解和镜质反射率(%Ro) 数据以及二维地震剖面分析。本研究评估了两口井中 Abu Roash F 和 G 组以及 Bahariya 组的油气潜力、有机质质量和热成熟历史。此外，使用 PetroMod 软件构建了两个埋藏历史模型，以确定研究序列在油气窗口和碳氢化合物生成时间方面的状态，这取决于建模的 %Ro。通过使用 Petrel 软件平台对二维地震线的解释，检测了生成的油气的构造背景和圈闭类型。结果表明，Bahariya 组和 Abu Roash F 和 G 组的烃潜力从差到很好，总有机碳达到 2.5 wt%。氢指数值表明干酪根类型主要为Ⅱ型、Ⅱ/Ⅲ型混合型和Ⅲ型。此外，研究井成熟度参数（%Ro、T _max和生产指数）和埋藏史模型表明，Abu Roash F、G组和Bahariya组在研究深度已达到成熟阶段。地震解释揭示生烃圈闭类型主要为正断层构造圈闭、地堑构造和背斜褶皱。
