US-focused Nighthawk Energy's production fell in November to 905 barrels per day, gross, (712 net) - down from 1,111, gross, (900 net) a year ago.
Output was down from 1012, gross, and 796, net, in October.
Net production is based upon Nighthawk's net revenue interest of approximately 82% save for the Monarch 10-15 well where HAWK has a 16% working interest.
Nighthawk said the production decrease for November was partially due to several wells requiring non-routine workovers to be performed.
The company performed additional workovers in December and expects to continue these workovers throughout January.
