Introduction

We Believe Materials Should Do More

Engineered Response

• Structural Materials

• React to External Stimuli

• Dissolve, Expand, Cement, React

• Based on “True Understanding” ofcontrolled oxidation/reaction chemistryof metals and other materials

Materials that respond to their environment to change state or perform additional functions- automatically

TervAlloyTM

Tervalloy alloys dissolve in a controlled, reliable manner

• Brine

• Acid

• Freshwater

• CaBr/offshore

Can be overcast or infiltrated into tools (sand control

Pumpable versions in development

• Tracer/chemical release

• Ph control

• Flow diversion

Realization of The Potential

Response Engineered Magnesium

High strength Patent Pending alloys and composites can be engineered to DO more:

• Dissolve

• Expand

• Release

• React

• Delay

• Other?

Magnesium alloys are stronger and withstand higher temperatures than dissolvable polymers

Tervalloy is tougher (ductile, not brittle) compared to prior dissolving materials

Improve efficiency/cost in hydraulic fracturing operations by reducing the need for drill out and cleanup runs

Can be engineered into many devices and applications, from Ball Drop applications, replacement of shear components, to sand control devices and many more.

TervAlloyTM Dissolvable Metals

Proprietary casting process

Patent pending suite of magnesium based alloys and composites

• Engineered degradation rates in different fluids and temperatures

Proprietary heat treatments and patented coatings

High strength and ductility

• 35- 40ksi yield strength with 8% elongation typical, up to 16% experimental

Can be easily machined into complex parts using CNC
