Nov 28, 2022 · Sandstone is a clastic sedimentary rock. It is the most common sedimentary rock found in sedimentary basins worldwide. Sandstone is sand cemented together into a rock. A sandstone rock can be simply identified by simply looking at it. However, a closer examination reveals an interesting mix-up of sediment, cement, and matrix. The user will be able to interpret the lithology by using several logs, there are gamma ray, spontaneous potential, resistivity, and density log.Basically, a formation with high gamma ray reading indicates that it is a shaly or shale, when the low gamma ray reading indicates a clean formation (sand, carbonate, evaporite, etc.), lithology interpretation is very important in reservoir ...From sandstone formations to carbonate reservoirs, Halliburton has a complete portfolio to enhance production.
