Fracking Plug Material: A Review of Processing, Microstructure, and Properties of Magnesium-Based Alloy

The advancement of dissolvable magnesium alloys for oil and gas industries’ applications marks a notable technological leap, driven by an international collaboration. These alloys incorporate metals like copper, nickel, and iron into magnesium alloy powder, creating a tailored galvanic cell or network structure at the microstructural level. This unique microstructure enhances both the strength and dissolution rate of the alloys. Moving from costly powder metallurgy to more traditional blend-press-sinter or ingot metallurgy methods has improved mechanical properties and controlled dissolution rates while reducing costs. The resulting microstructure, a precise combination of composition and processing, plays a crucial role in the alloys' performance, making them highly effective in fracking and other downhole applications. With optimized composition, microstructural control, and affordable processing, these magnesium alloys have become a transformative solution, improving operational efficiency and setting a new standard for materials in the industry.
