WebOil and gas exploration: Sandstone is an important reservoir rock for oil and gas exploration, and its porosity and permeability properties are critical … WebAn example of this might be a carbonate rock and a sandstone. Each could have a porosity of 0.2, but carbonate pores are often very unconnected resulting in its permeability being …
WebThe purposes of our study are to document the petrographic features of this sandstone- interpreted as a high-energy braid delta- and to explain the origin of its very good porosity and permeability. The porosity is so very good for a number of reasons. (1) Delta-plain sands were moderately sorted and well washed. Original porosity was thus high. Web2 days ago · Qiang et al. (2014) use seismic data to predict the lithology, fractures, and formation lithological porosity, and finally evaluate the sandstone gas enrichment area. Liu et al. (2011) and Li et al.
