Carbonate reservoirs, accounting for majority of the world’s hydrocarbon reserves, are well known for their heterogeneity and multiscale pore characteristics. The pore sizes in carbonate rock can vary over orders of magnitudes, the geometry and topology parameters of pores at different scales have a great impact on flow properties. A relatively simple way to integrate a set of digital pore spac...

In the primary and final designs of projects related to rock mechanics engineering geology, one key parameters that needs be taken into account is intact elastic modulus (E). To measure this parameter in a laboratory setting, core samples with high-quality costly tools are required, which also makes for time-consuming process. The aim study assess effectiveness two meta-heuristic-driven approac...

the significance of research article (ra) abstract as a key academic genre has recently motivated analysts to focus on this neglected area. considering a summary function for abstracts, most genre researchers have adopted the conventionally proposed introduction- method- results- discussion (or conclusion) (imrd) model for analysis. however, the problems reported, especially for results and dis...

Underground rocks usually have complex pore system with a variety of pore types and a wide range of pore size. The effects of pore structure on elastic wave attenuation cannot be neglected. We investigated the pore structure effects on P-wave scattering attenuation in dry rocks by pore-scale modeling based on the wave theory and the similarity principle. Our modeling results indicate that pore ...

Introduction: Impact melted materials occur in two main forms in the Ries impact structure [1]: (1) as isolated bodies of reddish, vesicular, fine-grained impact melt rock; (2) as in dividual glass y particles or c lasts in melt-bearing breccias or suevites. The latter lithologies have been the subject of a considerable number of investigations over the past few decades. In contrast, no detaile...
