Victoria Petroleum NL has been advised by the Operator, Oilex NL that Drill Stem Test No.1 over the interval 1,574 to 1582.5 metres was carried out in the Donga-3 exploration well over the weekend in response to oil shows seen in the primary target , the basal Moolayember sandstone over the interval1580 to 1582.5 metres.

The contents of the test tool and drill pipe string were reverse circulated out at the surface with a recovery from the test tool of 23 barrels of light, 45o API oil and 39 barrels of mud filtrate and formation water. The current operation is drilling ahead to evaluate the remaining target horizon in the well and reach total depth prior to running wire line logs to evaluate the zone from which light oil was recovered. At 0600 hours EST the well was at a depth of at 1597metres and drilling ahead.

Donga-3 is a 1,590 metre deep test of an interpreted up dip location of the basal Moolayember sandstone which recovered light sweet crude oil and high water rates in the Donga-1 and Donga-2 wells drilled in 1969 and 1979 respectively. The Donga Prospect is interpreted from seismic data to have the potential to contain up to 3 million barrels of recoverable oil, if oil is present.

Victoria Petroleum N.L. is earning a total 15% interest in the Donga-3 well and the surrounding permit ATP 805P from Oilex N.L. and Bow Energy Limited.

Commenting on the recovery of oil from Donga-3, Victoria Petroleum NL’s, Managing Director, John Kopcheff said: “The recovery of light oil in the first drill stem test for our first exploration well in the permit is most encouraging and substantiates our initial enthusiasm for the good chance of an oil recovery in the Donga-3 well.” “The full significance of the light oil recovery awaits evaluation by wire line logs and further testing.”
