Frac Hit Mitigation Chemical Technology
NoHIT™ is a patent-pending frac-hit mitigation technology via in-situ gradual and controlled pressuring of depleted rock intervals around parent well.
How does NoHIT™ work?
NoHIT™ is pumped with a normal preload treatment on the parent well and produces a slow in-situ gas generation reaction over 2–5 days.
NoHIT™ acts to temporarily pressurize the depleted rock around the parent and increase the associated rock stress.
NoHIT™ uses an atomized aluminum technology that creates a slow exergonic hydrogen gas-generating reaction with water when promoted with selective activators at reservoir conditions.
Parent well preload treatment with NoHIT™ protects the parent and encourages child fracs to move into undepleted high pressure intervals

NoHIT™ Effect on Parent Well’s Propped Frac Pack
NoHIT™ generates gas in-situ that energizes the depleted SRV of the parent well resulting in improved parent productivity.
NoHIT™ Simple Application
NoHIT™ is delivered to wellsite via standard chemical containers.
Pumped with preload ﬂuid, on-the-ﬂy, at low injection rate
Typical treatment/parent well:
2 – 5 days prior to hydraulically fracturing the child wells
