Santos and Magellan spud Winna-4

A SANTOS-Magellan joint venture has spudded the Winna-4 appraisal well in Cooper Basin permit PL3...

Yesterday morning, the well was drilling ahead at a depth of 43 metres, Magellan said.

With a planned total depth of 1,420 metres, the well is targeting up-dip oil potential in the western closure of the Murta Formation not addressed by Winna-2. In addition, Winna-4 will test secondary targets in the Birkhead and Westbourne Formations.

The Winna oil field contains three wells, two of which flowed from the Murta Formation. The field is about 2km west of the Thungo oil field, in the Nockatunga region of southwest Queensland.

Participants in the Winna-4 well are Santos Group (operator - 59.064%) and Magellan Petroleum (Eastern) Pty Ltd (40.936%).
