· The well is just beginning to stabilise after experiencing flow line problems caused by the very cold weather. We expect the initial flow rate of 100 bopd to increase somewhat

· There is no water production associated with the well

· Arbuzovskoye well 111 drilling ahead

· Group production is currently 2,500 bopd; however, 4 production wells are currently off line for remedial work on pumps
