Abstract In today's oil and gas landscape, production recovery from existing wells remains a pertinent challenge. The ever-increasing demand for hydrocarbons and the emphasis on optimized output have led to the endeavor of maximizing production from established wells. However, despite technological advancements, a significant proportion of these wells underperform, either due to inherent issues, such as formation damage, or a decline in reservoir pressure over time. Traditional methods like bullheading chemicals from the surface have struggled to consistently deliver efficient and sustained solutions. This pressing issue has prompted a shift toward innovative methodologies to restore and sustain productivity in underperforming wells. The oil and gas industry requires robust and sustainable techniques that can efficiently address these challenges, optimizing the productivity of existing wells. This paper presents a novel, data-driven process that uses a downhole, hydraulically activated system to restore and sustain productivity of sub-par producing oil and gas wells. The paper details the steps required to identify and restore the productivity of underperforming wells. Results are compared with traditional solutions based on bull heading chemical treatments from surface.
