Electron-Microscopy Studies of the Pore Space in Oil and Gas Carbonate Reservoir Rocks

Abstract

The procedure of identifying the microstructural types of pore space in carbonate rocks by the example of the Dimitrovskoe oil and gas condensate field is described. The microstructural features are studied with the use of an NVision 40 scanning electron microscope (Carl Zeiss) that allows us to examine the surface of fractures in the samples and polished sections prepared from the drilled rock core. As a result of the studies, rocks with different types of pore space are identified.
