ARC Energy Begins Senecio 2 Sidetrack Appraisal Well

ARC Energy reports that the Senecio 2 well located in the onshore Perth Basin Production License L2 is being drilled as a sidetrack from the Senecio-1 well bore to a total measured depth of approximately 2,850 meters.

The sidetrack is designed to penetrate the Dongara and Wagina Sandstone reservoir through the gas column at a relatively high angle to maximize formation contact. To minimise the formation damage interpreted from the Senecio 1 test results, a non invasive drilling fluid will be used to drill the sidetrack, and the well will be left as a barefoot completion (not cased).

Following completion of the sidetrack a cleanup flow will be undertaken while the rig is on location.

Participants in L1 and L2 (excluding the Dongara, Mondarra and Yardarino fields) and Senecio 2 are ARC Energy Limited as operator with 50% and Origin Energy Developments Pty Ltd with the remaining 50%.
