    Cores of other sandstone types fracture with sharp edges or shatter into small sharp fragments. Crystallized Sandstones are white and sugary and, in many cases, very hard and brittle. In some examples of this type, the grains are welded together and the cored rock has a smooth, polished appearance ( e.g. 23R ).

    Abstract. Characteristics and impact of asphaltene precipitation during CO 2 injection are investigated for a Middle East crude oil in both sandstone and carbonate cores through phase behavior studies, corefloods and analyses of the deposition process using a compositional simulator. In phase behavior studies, a light-scattering technique with near infrared was used to determine the onset ...
