Co-venturer Tap Oil said the Songa Mercur semi-submersible rig had drilled the well – 15km east of the Mutineer oil project – to a total depth of 3000m.
Preliminary results suggest the well had intersected about 3m of net hydrocarbons in the primary objective reservoir section, Tap said.
Looking ahead, the joint venture plans to run wireline logs and then possibly sidetrack the well to determine the further potential and hydrocarbon volumes.
“Initial well results are encouraging and wireline logs will determine the presence and extent of a live column,” Tap said.
Tap acquired its 8.2% stake in the WA-191-P permit from Woodside in March, which it said would enhance the commercialisation potential of its Amulet oil discovery in the neighbouring permit.
Fletcher-1 was targeting 20 million barrels of recoverable oil in a large structural closure in Cretaceous or Jurassic-aged sandstones.
The WA-191-P JV comprises Santos (operator) and Kufpec, both with 33.4% stakes, Nippon Oil Exploration, with 25%, and now Tap Oil with 8.2%.
