HARTFORD, Conn., April 4 /PRNewswire-FirstCall/ -- Magellan Petroleum Corporation (Nasdaq: MPET; ASX: MGN) ("Magellan") announced that its 100% owned subsidiary, Magellan Petroleum Australia Limited ("MPAL") advises the following drilling report.

Nockatunga Oil Fields - SW Queensland

The Thungo-11 appraisal well in PL 51 in the Cooper Basin of southwest Queensland has been cased and suspended as a future Murta Member oil producer.

Thungo-11 was the last well in the current 10-well Nockatunga drilling program which has been part of the Santos Cooper Oil Program. The Nockatunga drilling program has been very successful with all ten wells having been cased and suspended for production as future oil wells. Eight of the wells, including the two exploration wells, Dilkera North-1 and Kamel-1, will be completed as Murta Member oil wells and two of the Muthero wells, Muthero-4 and Muthero-5, will be completed as Birkhead Formation oil wells.

Planning for the completion and tie-in of the wells is well advanced with several of the new wells expected to be on-line within two months. A major upgrade of the surface facilities at the Thungo and Muthero fields is currently being undertaken to accommodate the increased production from these fields. Once the data from the program has been integrated into the existing data for the various oil fields in the Nockatunga area, planning will commence on a follow-up drilling program to further appraise and develop the Currambar, Dilkera and Dilkera North, Nockatunga, Maxwell and Maxwell South, Muthero, Thungo and Winna oil fields.
