The influence of carbonate reservoir vary widely from 5 to 20 % and 0.01 to pore types in the carbonate rocks results in widely scattered > 2000 md, respectively, affecting the field performance in data points in the velocity-porosity...

... quantitative estimates of total porosity and its size fractionation using digital rock workflows. The porosity fractions were categorized into three sizes: micro, meso and macro pore types based on the modified classification system in carbonates from Lonoy (2006). This porosity partitioning allows us...

... ABSTRACT Accurate identification of the spatial distribution of various pore types in carbonate reservoirs by seismic inversion is challenging due to the diverse pore structures resulting from deposition and diagenetic modification and low-resolution of seismic data. We use a bulk-frame...

... Summary The compressional and shear velocities of carbonate rocks are affected by many factors such as mineral composition, fluid content, porosity and pore type, as well as temperature and pressure. Among these factors, carbonate pore structure plays a significant role in determining...

... with dominant pore type and textural classification to distinguish samples with distinct porosity-permeability relations. RRT-4 samples are recognized by their grain-dominated texture along with high porosity (>20 %) and high permeability (>10 mD) values and have high 1/ Q values. RRT-1 and RRT-2 samples...

... Summary Compared with conventional reservoirs, complex reservoirs often have more variety of pore types and more complex pore shape. For example, carbonate rocks can have a variety of pore types, such as moldic, vuggy, interparticle, intraparticle and crack. Therefore the essential of rock...

... in carbonate reservoirs. To estimate S-wave velocity, pores of carbonate rocks are divided into four types considering pore shape and connectivity: vugs, interparticle pores, cracks and clay pores, the aspect ratio and porosity of each pore type are calculated by modifying the method proposed by Kumer and Han...

.... Detailed petrophysical analysis of over 8 wells reveals that "m" is a good indicator of pore structure. From log analysis, we find that the dominant pore type is dominated by micropores, where 1<m<1.9; the dominant pore types are intercrystalline and intergranular where 1.9<m<2.1; and the major...

While the brittleness index defined by Young’s modulus is not consistent with the definition in terms of (?+2µ)/? and Poisson’s ratio, Young’s modulus is a good indicator for the variation of crack density. Results of pore-type inversion show that the variation of pore types coincides with inverted...
