Abstract
Sand production remains a major challenge in thermal recovery processes such as steam-assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS), where high temperatures (>= 200-300 °C) exacerbate fines migration, scale deposition, and plugging of conventional sand control screens. This study presents the design, fabrication, and laboratory testing of a novel self-cleaning sand retention screen (SCSRS) concept tailored for high-temperature wells. The proposed design integrates hydrodynamic self-cleaning features through optimized wedge-wire geometry with periodic flow reversal capability and erosion-resistant high-temperature alloys. Experimental results demonstrate significantly reduced plugging rates and improved retained permeability compared to standard wire-wrapped and premium mesh screens. The findings suggest potential for extended screen life and sustained productivity in thermal heavy oil wells.
