Carbonate rocks have a very complicated and heterogeneous porous structure, which exhibits pore sizes ranging from submicron Manuscript received by the Editor September 21, 2023; revised manuscript received June 7, 2024; manuscript accepted June 7...

... of the simulation grid cells. INTRODUCTION Carbonate rocks from the presalt section of the Santos Basin, Brazil, exhibit high textural heterogeneity, showing a complex porous system with pores coexisting at different scales (Corbett and Borghi, 2013). This complexity makes it challenging to understand...

... become a common practice in carbonate rock typing systems (Xiao et al., 2017; Liu et al., 2019) and the development of prediction models, owing to its robust correlations with porosity and permeability (Kolodzie, 1980; Ma et al., 2019). Both PTD segmentation and R35 methods have proven reliability...

Three carbonate rock plugs with differing ϕ and pore-size distributions were subsampled for this study. Three water saturation states were produced for each sample: saturated, centrifuged...

... of the resulting model (less than 20 mm in each direction). This technical note presents a detailed workflow on how to fabricate a carbonate rock replica at the micron scale. To test this workflow, a pore network was obtained from tomographic data of a reservoir rock core located in Mexico (1 mm in diameter and 2...

...Qifei Huang; Qifeng Dou; Yuefeng Sun Lack of accurate estimation of reservoir permeability has been one of the most challenging problems for enhanced hydrocarbon recovery. Pore-structure variation in carbonate rocks caused by diagenesis controls reservoir permeability heterogeneity. In this paper...

... in natural rocks. Therefore, a modified capillary model for interconnected pore space in water-saturated, water-wet carbonate rocks is presented in this study. It describes a rotated pore channel with a radius varying between its two extreme values r t (pore throat) and r b (pore body), and is applicable...
