The joint venture completed fracture stimulation of the final three wells of a four-well program in November 2014.
The Etty-1 vertical well was stimulated over four intervals, one in the Daralingie Formation and three in the Toolachee Formation. The well cleaned up to a peak flow rate of 0.9 MMscfd and was shut-in on 15 January 2015 having achieved flow test objectives. Immediately prior to shut-in, Etty-1 was flowing at 0.7 MMscfd through a 24/64' choke with wellhead pressure of 405 psi. Gas analysis indicated approximately 70% methane and 30% CO2.
