The second template is to derive relationships between total porosity and elastic property. The template is constructed by using a rock physics model, differential effective model (DEM) by Berryman...

... common and widely used is the porosity-permeability (poro-perm) relationship. Poro-perm relationship relies on the basis that all pores contribute to fluid flow. However, any heterogeneity, such as presence of isolated pores could cause this poro-perm relationship to fail. Hence, this paper aims...

... 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...

..., an accurate method is required to ensure hydrocarbon development is effective and efficient. Challenges in the characterization of the carbonate are related to rock type and porosity. The permeability of rocks cannot be determined only by porosity. The method that can be used to determine rock type and rock...

The simulation showed that the sand production of a specimen increases with three influence factors, including the initial overpressure, the porosity and the sand grain size. Some critical points were discovered and studied in the investigations of each...

... (YM_Cali) enhance brittle nature of rock, while higher concentration of organic richness (TOC), porosity (φ T ), clay contents, and Poisson's ratio enhance ductile nature of rock. The gamma ray log indicated a decreasing trend with an increase in brittleness index. However, there is no significant...
