    JINGEMIA OILFIELD APPRAISAL PROGRAM UPDATE (VOY 6.27%) Voyager has been advised by the operator, Origin Energy, that preparations are underway to drill the sidetrack well Jingemia-3, to be used as a water injector to maintain field pressure during production of the Jingemia oil field. The well is being designed to intersect the Dongara Sandstone reservoir approximately 400 m north-northwest of the Jingemia-2 intersection. It will take approximately 1 week for Jingemia-3 to intersect the reservoir. Analysis of the Dongara Sandstone reservoir in the Jingemia-2 well has indicated it to be of poor reservoir quality and unsuitable for water injection likely due to thinning of the section from Jingemia-1. The Jingemia-2 well was a significant, 1 km step out to intersect the top reservoir on the nearest seismic line south of the discovery well. Jingemia-2 intersected the Dongara Sandstone at a depth approximately 66 m below the top of the sands in Jingemia-1. It has not yet been possible to determine whether a thin (1-3 m) oil saturated interval at the top of the Dongara Sandstone related to residual saturations of oil or the base of a live oil column. Commenting on the results to date, John Begg, Voyager Managing Director stated that, “Although the results of Jingemia-2 appraisal have yet to be fully incorporated into our mapping of the Jingemia field, no revision of pre-drill reserve estimates of approximately 5 million barrels are warranted at this stage and there remains potential for reserves upside.” Participants in EP 413 and Jingemia-2 are: Origin Energy Developments Pty Limited* (Operator) 49.189% Hardman Oil and Gas Pty Ltd 22.376% AWE (Perth Basin) Pty Ltd 15.245% Voyager Energy Limited 6.270% Victoria Petroleum NL 5.000% Norwest Energy NL 1.278% Roc Oil (WA) Pty Limited 0.250% ARC Energy NL 0.250% John Kevin Geary 0.142%
