Sandstone is the best known petroleum clastic reservoir rock composed of mainly quartz and/or feldspars, and typically deposited by relatively high-energy processes. Sandstone reservoirs have good porosity and high permeability. However porosity and permeability mainly depend on the depositional environment and burial history diagenesis.Jul 18, 2022 · The interpretation of depositional environment and diagenesis controls on petroleum reservoirs are a major challenge that has an impact on the petroleum system of hydrocarbon reservoirs.

However, some oil fields worldwide lack core samples, which are needed for ...

Aug 13, 2019 · Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock.
