Magellan is pleased to announce that the Operator for our Nockatunga assets (PL 33, 50 & 51
and ATP 267P), Santos Ltd, has advised that the EIES Rig 20 has commenced mobilisation to
Petroleum Lease 33 in South West Queensland and will shortly commence operations on the
first well in a three well oil delineation and exploration program to be conducted within PL 33, PL 51 and ATP 267P for the Nockatunga Joint Venture parties. The three initial well locations have been selected following the interpretation and mapping of the 3D seismic survey acquired
by the Joint Venture in the area last year. Further drilling is being planned for the area in
The first well, Winna-4, will target the Murta Member in a location updip of the Winna-2 well
which encountered a thin oil column. An open hole Drill Stem Test (DST) in Winna-2
recovered some 1.6 barrels of oil. At the time of drilling (1987) this small oil recovery was
deemed to be sub-economic and the Winna-2 well was plugged and abandoned. Following
acquisition and interpretation of the 3D seismic data, it has been established that there is an economically attractive potential attic of oil located updip of the Winna-2 well location.
The Muthero-3 delineation well and Currambar-1 exploration well will be drilled following the
Winna-4 well. Information on these wells will be provided closer to their respective spud
Winna-4, which is expected to spud over the coming weekend, will take some 11 days to drill,
case and suspend.
Participants in the Winna-4 well are:
Petroleum Title:|| PL 33.|
|Location:|| Cooper/Eromanga Basins, Queensland.|
|Coordinates:|| Latitude: 27° 43' 31.88" South.|
|Longitude:|| 142° 32' 25.54" East (GDA 94).|
|Drilling Rig:|| EIES Rig 20.|
|Proposed Total Depth:|| 1,395 metres RT.|
|Objective:|| The Murta Member is considered the primary objective of the well as
the Winna-4 location is mapped to be updip of the Winna-2 Murta oil
recovery. The Birkhead Formation is considered as a secondary
target as it is oil productive in the nearby Nockatunga Field.
|Expected Spud date:|| 27 November 2005|
