Well Stimulation

Chemicals alone are often not enough to remove stubborn well debris such as scale, paraffin and drilling mud. Greenwell’s well stimulation and cleanout service, the G-Terminator™, combines Greenwell chemicals with a proprietary-designed oscillation tool to open perforations cost-effectively and enhance revenue immediately. Clients often recover the cost of the service in less than 30 days. Whether boosting stimulation on an older well or using Greenwell's tool on a simple acid job, the G-Terminator goes far and above other services, increasing production immediately after deployment.

“Since we’ve operated this well it has not produced over 5 bbl/day. Greenwell’s G-Terminator service boosted production over 400%. It was quick and easy with barely any downtime. I’m extremely pleased with the results.”

— John Day, President of Texron Operating, LLC


Proven by more than 250 oil and gas companies, the oscillation tool has successfully treated more than 6,500 wells in 26 states and 37 international areas.

Bbl/day

“We tried chemical and hot oil treatments but they only had a minimal effect…. After deploying the [G-Terminator] service, production came back on line at rates above levels when we first drilled the well years ago. And we keep seeing improvements. Nearly every 10 days, production is increasing by roughly
a barrel
