1991 3 1 Abstract. Mean porosity and permeability of many sandstone intervals can be predicted prior to drilling. The predictive technique involves use of multivariate regression equations derived from calibration data sets. The effectiveness of this technique is illustrated by case studies, including several predrill porosity and permeability predictions.
2011 11 15 In sandstone cores, the permeability decayed by 10–20% with increasing stress while the porosity decreased by about 3%, similar to what is expected from a Carman Kozeny type correlation. In some carbonate cores tested, the permeability was altered by an order of magnitude with the same porosity reduction.

2021 8 30 The natural sandstone has an average porosity of 8.02% and a bulk density of 2.43 g cm −3. The average P wave velocity of the sandstone samples was 2.32 km s −1 and the variation is within ± 0.05 km s −1. In this study, the porosity term includes all voids within sandstone samples, such as pores and microcracks.

A classification of porosity in sandstones is proposed to recognize primary and secondary porosity. Secondary porosity caused by dissolution of framework grains is very common in sandstones. Dissolution of both carbonate and
Natural aggregates are porous, and its porosity ranges from 2% to 40%. For instance, the porosity of intrusive igneous rocks maybe 2%, and maybe up to 5% for dense sedimentary rocks, and
