An oil column of up to 4 meters has been confirmed by pressure data in the primary objective with an oil water contact consistent with the oil water contact in the Woollybutt-3 and 4 wells. Tapís interpretation is that the Woollybutt-5A well has extended the South Woollybutt Field at least 4 kilometers to the south.
The deeper Intra Barrow interval, some 50 meters below the primary objective, (gross interval of around 12 meters) has been confirmed to be hydrocarbon bearing by wireline testing and sampling. These hydrocarbons are interpreted to be light oil, which will be confirmed by laboratory analysis. However, it would appear that these hydrocarbons are not connected to the Intra-Barrow oil columns intersected in the Woollybutt-3 and 4 wells.
Data obtained from Woollybutt-5A well will now be further interpreted to evaluate the optimal development of the South Woollybutt oil field. As anticipated the joint venture is considering the drilling of a further well, Woollybutt-6, in 2006 to evaluate the field.
The Woollybutt field oil production FPSO was temporarily shut-in on January 8, 2006 due to tropical cyclone Clare, but the vessel was not disconnected from the wells. Production restarted yesterday afternoon.
Production optimization operations will re-commence once the field is back on-line.
WA-25-L Joint Venture participants are Eni Australia Ltd as operator with 65%; Tap West Pty Ltd with 15.00%; and Mobil Australia Resource Co Pty Ltd with 20.00%.
