... ABSTRACT The quantification of microporosity leads to determine its empirical relationships with permeability and sonic velocity of Miocene carbonate reservoirs. These relationships can be used for a better understanding of the reservoir systems. This study on Miocene carbonate reservoirs...

... A comprehensive petrographic characterization has been conducted on the microporosity of the organic-rich carbonate Hanifa Formation in Jafurah Basin, Saudi Arabia. Hanfia Formation composed of organic-rich muddy limestone with more than 90 % carbonate minerals content. Based on XRD analysis...

... of the topmost part of Khuff-C reservoir. High-resolution profiles of acoustic (p-wave) and (s-wave) were recorded under ambient conditions. SEM and petrography were used to detect MFs and visual microporosity (MP); the latter was calibrated with log-derived porosity. Impulse hammer tests were run...

... Abstract This paper aims to quantify microporosity and access its impact on reservoir quality properties, to identify Hydraulic Flow Units (HFU) using core porosity and permeability data, to predict HFU and accurately estimate permeability in un-cored intervals/wells. Mercury Injection...

... morphologies with intercrystalline contacts ranging from facial to sub-punctic, which display relatively a good microporosity developement, whereas crystals that show anhedral compact character with coalescent/fused intercrystalline contacts are rarely associated with any microporosity.

... obtained through X-ray µCT and optical microscopy imaging provided the geometrical parameters required for modeling the elastic properties using elastic effective medium theories. The discrepancy of the modeled and measured values was used to infer the amount and the aspect ratio of the microporosity...

... Abstract Carbonate reservoirs often contain a complex mixture of pore sizes. In Bul Hanine field, Arab-DIII reservoir is almost entirely microporous throughout the field. Microporosity affects log responses and fluid flow properties. Proper identification and quantification of different...

... Abstract Carbonate reservoirs are known for complexity to oil recovery industry, one reason is the dual-porosity pore system. In macroporosity regions where pores are mostly effective for fluid flow and therefore viscous flow will play a role in oil extraction, while in microporosity regions...

.... The segmentation results in quantification of the macroporosity, microporosity and of specific minerals such as pyrite. The autosegmentation algorithm is based on an advanced statistical analysis of the global and local intensity distributions of the tomogram. The method involves local normal distribution fitting...

... Abstract Microporosity is very common in limestone reservoirs globally and is especially significant in many large Mesozoic reservoirs in the Middle East. Despite its common occurrence there is: Wide variation in its definition, Uncertainty around characterization, genetic controls...

... Abstract The presence of microporosity in carbonate rocks is notorious for suppressing the response and creating a low resistivity contrast between water and oil. Microporosity can have a major impact on hydrocarbon volume because the capillary bound water in micropores can result in an over...

... with microporosity present. We describe a new approach of using a hybrid saturation-inversion-recovery (HSIR) sequence that takes advantage of the higher sensitivity for the short inversion times in the IR sequence and the efficient data-acquisition feature in the SR sequence. To demonstrate the benefit, we...
