Experimental approach for assessing filter-cake removability derived from reservoir drill-in fluids

Abstract Predicting formation damage in cased-hole and open-hole completion wells is of high importance. This especially relevant when the caused by reservoir drill-in fluids hence being well-bore induced. Cake filter removal has proven to be a good approach estimate induced evaluate fluids’ performance. We present an experimental methodology cake removal, which could achieved during well's initial production. An improved setup, ones presented literature, been developed enhance data quality. A twofold was used for setup design, first, it can integrated with devices static/dynamic filter-cake. Second, simulate more realistic cases (field related) adjusting experiment parameters. Hence, replicate expected drawdown pressure as well corresponding flow rate studied reservoir. Three key indicators directly related filter-cake were evaluators this work. Lift-off pressure, internal external cakes efficiency. fluid systems studied, two polymer-based one potassium carbonate. Results show that required initiate collapsing process not significant. Polymer-based drilling showed better performance terms cleaning efficiency comparing Moreover, we observed filtrate volume no clear relation degree residual damage.
