Overall the results from the Intra-EVCM zones were in line with expectation and consistent with those observed in the original wells, Yolla-1 and Yolla-2.
The Upper-EVCM gas and oil zone was not included in the development plans for Yolla, but one objective of the Yolla-3 well was to provide further evaluation of this zone. Core and log data showed a 10m gas column overlying an eight to 10m oil column. The production test was conducted in the gas column, plus one metre into the oil column.
As a result the joint venture has agreed to include the Upper-EVCM zone in the Yolla-3 well completion to allow for further evaluation and possible future long term production from this liquids rich interval.
The rig is being readied to mobilise to drill the Trefoil-1 exploration well, approximately 40km west of the Yolla “A” platform for the T/18P Joint Venture.
Participants in T/L 1 are AWE Petroleum 30%, Origin Energy Resources Limited 32.5%, CalEnergy (Australia) 20%, Wandoo Petroleum 12.5% and Origin Energy Northwest Limited 5%
