Abstract
A material sample representative of a subsurface formation is tested for its dynamic interaction with a coring fluid. The material sample is subjected to a pressurized and agitating coring fluid to simulate a coring operation. Thereafter the material sample is x-ray scanned to identify the extent of coring fluid invasion during the dynamic interaction of the material sample and the coring fluid.
