Exillon Energy announced the successful testing of the EWS-15 on a 10 mm choke which resulted in an oil flow rate of 1140 bbls/day.
The EWS -15 well, which was spudded on December 29, 2009, was designed to test the northern extension to the EWS I field in Siberia. The well flowed water-free oil naturally to the surface with a flow rate of 1140 bbl/day on a 10 mm choke and 570 bbl/day on an 8 mm choke, and was drilled on a turn-key contract for a total consideration of US $0.975 million. The well reached target depth within the Jurassic P reservoir at 1827.5-1842.7m, confirming the presence of 15.2 m of net oil pay within the Jurassic. This is the thickest net oil pay encountered within the EWS I field to date. The average net oil pay within the Jurassic reservoir of the EWS I field, according to the Miller and Lents September 2009 reserves report is less than 5 m. The well confirmed the presence of a reservoir in the pre-Jurassic complex, though this interval has flowed water from the EWS-15 well.
The well was drilled directionally 1.4 km to the north from the existing EWS I field, and is now being connected to existing production facilities in the EWS I field.
