Impact of Drilling Fluid Contamination on Performance of Rock-Based Geopolymers

Summary Our objective is to present selected rheological and mechanical properties of rock-based geopolymers contaminated with different concentrations drilling fluids. The possible flash setting the maximum intake fluids before seeing a dramatic deterioration are presented. Rock-based designed for cementing conductor surface casing were prepared cured up 28 days at 22°C atmospheric pressure. Water-based (WBDFs) oil-based (OBDFs) in accordance recommendations from petroleum industry. fluid samples prepared, their viscous behavior was characterized after hot-rolling. geopolymeric slurries mixed then blended volumes. tested time intervals. American Petroleum Institute (API) Class G neat cement used as reference. These same geopolymer benchmarked those cement. obtained showed that more sensitive WBDFs than OBDFs. However, Portland samples, results opposite, contamination effect OBDF on noticeable WBDF. impact function curing time. Although strength retrogression early time, buildup compensated contamination.
