In the past the private equity firm Cadent Energy out of Stamford CT invested in Nytis. Nytis is no longer on their "Active" partners page under the 'Portfolio' tab, but used to be, according to a Google search for Nytis I tried recently, and found little else but this: http://www.cadentenergy.com/portfolioPro.asp?Com=Nytis%20Exploration.
