TervAlloy engineered disintegrating fracturing balls from Terves have been deployed successfully in horizontal fracture completions in North America since their introduction in late 2014. These new, lower-cost and higher-strength metallic tools are easier to store and handle and less prone to early degradation than previous-generation dissolvable metals. Nanocomposite metals are lighter and stronger than aluminum, and are engineered to disintegrate in a highly controllable manner when exposed to completion fluids at downhole temperatures. Terves has proprietary and patented nanocomposite technology and is a leading supplier of disintegrating magnesium fracturing balls and completion-tool components. TervAlloy engineered magnesium-alloy fracturing balls maintain their shape and do not begin degrading in the ball-drop system, while effectively actuating sleeves or sealing fracture plugs at pumping pressures that can exceed 10,000 psi. Once deployed, the engineered alloy tools respond to a combination of completion fluids and bottomhole temperatures to degrade into soluble micron-sized particles that easily circulate out of the well. Within 1 to 5 days after completing the fracturing, tools are completely disintegrated, leaving an unobstructed wellbore, without requiring coiled tubing drillout operations. Five formulations of TervAlloy magnesium alloys are available, with useable tensile strengths up to 45,000 psi and with a range of dissolution rates.
