The Ranikot sandstone Formation was investigated using TOC and Rock-Eval pyrolysis measurements. Ranikot Formation encountered in Bijnot well, Fort Abbas has been evaluated, which lies in Bahawalpur, middle Indus basin, particularly in Punjab platform. Analysis has been performed on sandstones, twenty well cutting samples of Ranikot Formation has been evaluated. Formation is predominantly sandstone with interbeds of shale. The analysed samples contains TOC ranging from 0.76–3.1 wt.%, The S2 values of Rock-Eval shows poor potential with values ranging from 0.46–1.05 mg HC/g rock. The samples have low hydrogen index values ranging from 21–113 mg HC/g TOC. Kerogen is predominantly Type III land derived organic matter. The analysed samples have T max ranging from 413–509°C. The upper part of formation from 490–560m depth generally exhibits good to very good TOC content and is in the transition between immature and mature zone (Tmax 430–431°C). The genetic potential in the entire rock unit is poor < 2.0 mg HC/g rock. On the basis of analysis performed the studied samples have shown that the formation has poor potential.

巴基斯坦旁遮普地台盆地 Ranikot 砂岩地层评价

使用 TOC 和 Rock-Eval 热解测量对 Ranikot 砂岩地层进行了调查。在 Bijnot 井中遇到的 Ranikot 组已被评估，Fort Abbas 位于印度河流域中部的 Bahawalpur，特别是在旁遮普台地。对砂岩进行了分析，评估了 Ranikot 组的 20 个井切割样品。地层主要为砂岩，夹有页岩。分析的样品包含的 TOC 范围为 0.76-3.1 wt.%，Rock-Eval 的 S2 值显示出较差的潜力，其值范围为 0.46-1.05 mg HC/g 岩石。样品的氢指数较低，范围为 21–113 mg HC/g TOC。干酪根主要是 III 型陆源有机质。分析样品的 T max 范围为 413–509°C。地层上部 490-560m 深度通常表现出良好到非常好的 TOC 含量，处于未成熟区和成熟区之间的过渡区（Tmax 430-431°C）。整个岩石单元的遗传潜力很差 < 2.0 mg HC/g 岩石。根据所进行的分析，所研究的样品表明该地层的潜力很差。
