Effect of different types of stimulation fluids on fracture propagation behavior in naturally fractured carbonate rock through CT scan

Journal of Petroleum Science and Engineering, 2021
Acid fracturing of carbonate rock starts with formation breakdown and fracture propagation caused by stimulation fluids. The effectiveness of acid fracturing largely depends on the behavior of fracture propagation. While fracture propagation of fractured

Wettability Alteration of Carbonate Rock by Chelating Agents and Viscoelastic Surfactants: Synergetic Impact

Energy & Fuels, 2022
The two most important EOR mechanisms for oil-wet carbonate rock are IFT reduction and wettability alteration. By altering rock surface wettability, the resulting positive capillary pressure can help imbibe water and displace oil from the rock matrix ...

Wettability Alteration of Locally Synthesized Cationic Gemini Surfactants on Carbonate Rock

Journal of Molecular Liquids, 2021
Carbonate reservoirs are mostly oil-wet and tend to be naturally fractured, leaving a large portion of oil inside the rock matrix after secondary recovery. Cationic surfactants that combine interfacial tension (IFT) reduction, wettability alteration, and

Lattice-Boltzmann simulation of dissolution of carbonate rock during CO2-saturated brine injection

Chemical Engineering Journal, 2020
Geological carbon sequestration is one of the key effective technologies proposed to reduce the atmospheric CO2, which is essential to achieve the net zero-emission target.

Seismic velocities in carbonate rocks

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1991
Abstract Seismic velocities were measured in the laboratory vs pressure, temperature, and saturation on over 80 cores from various carbonate reservoirs in Alberta, using an ultrasonic pulse transmission method. Porosity, permeability, electrical properties, and capillary pressure were also measured in order to ...

Hydrogeology of carbonate rocks

1999
Carbonate rocks are sedimentary type of rocks containing more than 50% carbonate minerals which are mainly calcite, CaCO3, and dolomite, CaMg(CO3)2. The carbonate minerals could be a result of chemical precipitation, organic processes or may occur as detrital material.
