Intervale, PDC Logic founder Tom Waitman said, is "uniquely positioned to drive rapid growth of the business as we look to enter additional territories and commercialize new bit products."

Intervale has raised some $1.3 billion to invest in midsize oil field service companies and equipment makers since 2006. The company collected $495 million from investors in 2014 to pump capital into small oil field services companies, its third fund.
