Eromanga, which joins local operator Gavea Oil & Gas in the well, said a gas kick was encountered at a depth of 171 metres and an inflow of oil seen at 295m.
“This is a very positive result in that petroleum has flowed into the PTA-3 well bore, which appears capable of recompletion and testing to determine if commercial production can be achieved,” Eromanga chief executive Phil Galloway said.
“At this time, we do not expect that the risk and cost of drilling a sidetrack well will be necessary.”
Last February Eromanga farmed-in to earn a 50% stake in Block 330 last February, with PTA-3 the first of two wells planned for the basin.
The second well will be drilled in Block 430, in which Eromanga also holds a 50% interest.
Following this campaign, the company plans to participate in drilling up to three wells in the Reconcavo Basin as part of its JV with Silver Marlin.
In addition, Eromanga has also secured a 40% stake in two blocks in the Rio do Peixe Basin with Gavea that were released under Brazil’s ninth licensing round.
