Leakoff Core Holder Special core analysis Instruments

The LEC Series core holders are specifically designed for fluid invasion studies, e.g. drilling fluid in the surrounding formation. The invasion phenomenon is accurately replicated by tangentially circulating fluid across one of the core end faces; achieved by virtue of a special leakoff end. Moreover, fluids can be injected into the sample via either end of the core holder. Specific examples of the possible applications include static and dynamic filtration tests to evaluate erosion effects and permeability alteration studies.
