After leaving the U.S. Marines around 16 years ago, Mike Cramer joined the drilling industry, focusing on environmental applications. In 2003, after working with direct-push and hollow stem rigs, he was introduced to the sonic drilling method.
“My first experience with sonic was revolutionary to say the least. From there on out, it was the only way to drill for me. Sonic provided the versatility and speed, along with a huge increase in safety. It was also fun and exciting to use,” Cramer says.
