A reader alerted me to a RMOJ story about Petro-Hunt targeting the Red River formation with a vertical wildcat about 13 miles northwest of Glendive. This is near a successful Petro-Hunt Red River with an IP of 200 bopd.
In addition, a Petro-Hunt well in the same area has produced 38,000 bbls of oil between November, 2010, and Jnuary, 2012, from a vertical well that targeted the Ordovician.
According to the RMOJ, Petro-Hunt has been drilling vertical and horizontal Red River wells in Dawson County for the past two years "with varied success."
So, that answers one of the questions regarding the Glendive area.
