Importance of Microstructure in Carbonate Rocks: Laboratory and 3D-Imaging Petrophysical Characterization

نویسندگان

چکیده

Carbonate rocks are considered to be essential reservoirs for human development, but known highly heterogeneous and difficult fully characterize. To better understand carbonate systems, studying pore-scale is needed. For this purpose, three blocks of (chalk, enthrocal limestone, dolomite) were cored into 30 samples with diameters 18 mm lengths 25 mm. They characterized from pore core scale laboratory tools. These techniques, coupled X-ray micro-tomography, enable us quantify hydrodynamic properties (porosity, permeability), elastic structural (by acoustic electrical measurements), distribution centrifugation calculations). The have similar typical homogeneous specific characteristics depending on the rock type. In same family, sample different similarities established between certain measured properties. example, permeability) (formation factor, tortuosity) may properties, due their cohesion, which itself depends size distributions. Microstructure understood as one a thus must taken account initial rocks.

Characterization of Bitumen Bearing Carbonate Rocks

Several countries, including Canada, contain sizeable bitumen resources in highly fractured carbonate rocks. Any possible recovery of bitumen from these reservoirs will be highly dependent on proper understanding of the rock and fluid properties and how they vary in the reservoir. These carbonates are extremely heterogeneous, and as a result proper reservoir characterization is challenging. In ...

Pore-scale Characterization of Carbonate Rock Heterogeneity and Prediction of Petrophysical Properties

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...

3D Characterization of Uniaxial Compressive Strength of Transversely-Isotropic Intact Rocks

The uniaxial compressive strength (UCS) of intact rocks is one of the key parameters in the course of site characterizations. The isotropy/anisotropy condition of the UCS of intact rocks is dependent on the internal structure of the rocks. The rocks with a random grain structure exhibit an isotropic behavior. However, the rocks with a linear/planar grain structure generally behave transversely-...
