Santos has plunged and abandoned the Sampdoria-1 exploration well on the Wompi block in ATP 752P, Queensland, Australia, after reaching a depth of 1,823m in the Toolachee Formation.
The well was drilled 4km north-east of the Geona oilfield. The primary targets were the sands of the Birkhead formation and Hutton sandstone, with secondary targets in the McKinlay member and Namur formation.
Santos recorded hydrocarbon shows in the Murta formation and Hutton sandstone, with a drill-stem test across the show at the top of the Hutton sandstone recovering 2.8 barrels of mud-cut formation water.
Senex Energy is a joint venture partner in the project with a 22.75% working interest and participated in the drilling with no cost.
