The repairs to the cranes on the Kan Tan IV drilling rig were completed at the time when operations on the Rockhopper 1/ST 1 well commenced.
The side track is designed to appraise the oil and gas zones discovered in the Rockhopper 1 well and is being drilled to intersect the main reservoir sections approximately 1.3km south and down dip from their penetration in Rockhopper 1. This will allow the volume of oil and gas discovered in the Rockhopper structure to be fully evaluated.
It is anticipated that the sidetrack will take approximately one week to reach the primary reservoir section and a further two weeks to complete data acquisition and plugging and abandoning operations. As planned, the sidetrack and the original Rockhopper 1 well will be plugged and abandoned.
Rockhopper 1 is an exploration well located in exploration permit T/18P, operated by Origin some 38km west of the Yolla gas field and approximately 10km north-north-east of Trefoil 1.
T/18P participating interests include: Origin Energy Resources, a wholly owned subsidiary of Origin Energy, (operator) with 39%; AWE 47.5%; CalEnergy Gas (Australia) 8.5% and Innamincka Petroleum 5%.
