LONDON, Oct. 8 -- Tap Oil Ltd. has intersected the target oil reservoir in the Woollybutt-4H development well on the Barrow subbasin in permit WA-25-L off Western Australia. Tap Oil, a partner in the project, tested the well flow and will temporarily suspend the well as it prepares to connect it to a floating production, storage, and offloading vessel on the northern lobe production facilities next year. This is the first well launching the Woollybutt South Development (OGJ Online, Jan. 5, 2007).

Woollybutt-4H, sidetracked from the existing Wollybutt-4 well, is expected to help produce 14,000 b/d from the field next year. The joint venture partners successfully drilled a horizontal section of more than 400 m through the reservoir objective after reaching a TD of 3,400 m. They will move to the Woollybutt-6 appraisal well location to investigate the possibility of more producible reserves.

"Should Woollybutt-6 be successful, it too will be tied in immediately and will augment the above production rate estimate," Tap Oil said.

Partners are ENI Australia, which has 65% interest, Mobil Australia Resources 20%, and Tap Oil 15%.
