The purpose of the production test is to evaluate the productive capacity and potential of the Patchawarra Formation oil discovery, which, on open hole Drill Stem Test (DST), flowed 1,100 barrels of oil per day (BOPD) and 2.8 million cubic feet of gas per day (MMcf/D) on a 1/2" choke. Significantly, the current production test has yielded a lower gas to oil ratio compared to the DST and there has been no water produced to date from the production test.
While the production test at Kiana-1 is testing the upper hydrocarbon zone within the Patchawarra Formation that was tested by DST 4, a lower Patchawarra Formation reservoir was identified using wireline sampling at the time of drilling. This zone was not validly tested with the drilling rig at the time and there is now potential to better assess this zone subject to operational considerations at the conclusion of the current production test.
In addition, and subject to sustained and encouraging production from the zone currently being tested, consideration will be given to the drilling of an appraisal well, Kiana-2, in the near term, subject to joint venture process and approval and rig availability.
Participants in the Kiana-1 production test are Magellan Petroleum Australia Limited with 30.0%; Beach Petroleum as operator with 40.0%; Great Artesian Oil & Gas Limited with 30.0%.
PEL 106 Udacha-1 Well
Magellan has taken up its option under the agreement with Great Artesian Oil and Gas (GOG) to farm into the Udacha-1 well to earn a 30% interest in any petroleum production licence resulting from a commercial discovery.
GOG estimates that the Udacha prospect has the potential to accommodate up to 2.3 million barrels of recoverable oil or some 10.5 BCF of gas (both at a P10 level of confidence) with the Patchawarra Formation providing the primary reservoir target. The Toolachee and Epsilon Formations and Tirrawarra Sandstone represent secondary reservoir targets. Drilling of the Udacha-1 well will commence in January 2006.
Under its agreement with GOG, Magellan has the option to earn an interest in PEL 106 and/or 107 by funding additional drilling in these permits.
Participants in the Udacha-1 Well are Magellan Petroleum Australia Limited with 30.0%; Great Artesian Oil & Gas Limited with 32.5% and Beach Petroleum as operator with 15.0%; Enterprise Energy NL with 12.5%; Rawson Resources Ltd with 10.0%
