Oil and Gas
SoluMag® dissolvable magnesium alloys have high compression and tensile strengths to hold pressure in demanding, plug and perf as well as sliding sleeve ball seat applications.
SoluMag® has a controlled corrosion rate to ensure complete dissolution in brine environments once its functional life is over.
These magnesium material don’t require acid or other aggressive chemicals to dissolve and will completely dissolve in fracking fluids during the flow-back portion of the process.
This combination of strength and corrosion properties was developed based on Luxfer MEL Technologies’ extensive knowledge of magnesium alloys and how these materials function in severe applications.
SoluMag® 1100 has a corrosion rate of 1100 MCD (milligrams/sq cm/day) in 3% KCl solutions at 200F. This high strength magnesium alloy has good ductility and works well in frac plugs and balls. SoluMag® 1100 needs at least 10,000 ppm chloride ion to corrode actively.
SoluMag® HD has the highest ductility of all of the SoluMag® alloys. This material exhibits high ductility in longitudinal and transverse directions. This version of SoluMag® is for applications where deformation of the material is needed for sealing against casing, as an example.
SoluMag® HS has the highest tensile strength of all of the SoluMag® alloys. The HS version achieves these high levels of strength and has correspondingly low ductility. SoluMag® HS is available in three different tempers to tailor the tensile strength.
The SoluMag® Hollow Ball is designed to reduce the amount of time large diameter balls take to dissolve after completion of frac operations, allowing the well to be brought on production sooner.
Information Available to Assist in Design
Our Magnesium Design Guide helps explain the wide world of magnesium alloys. It is an in-depth look at the alloys, forms, properties and methods used when working with this light weight metal.
When evaluating materials for any design, understanding how the material handles stress is important for success. This information is in longitudinal and transverse orientations and can be used in FEA modelling.
SoluMag® alloys have been tested in a variety of aqueous solutions. This information will help the designer understand corrosion rate in various solutions so you can accurately predict product life.
