First Shale Gas Discovery in Cooper Basin Producing 1.8 Mmcfpd.
Drilling Activity Details
Drilling Activity Summary
Description
Up to 2 million cu. ft. per day of gas flowed at Beach Energy's #1-Holdfast exploratory shale gas well in the Cooper Basin of South Australia. According to Beach, this is the first shale gas well to explore the Roseneath-Epsilon-Murteree shale sequence in the Cooper Basin. The Adelaide-based company's well is in the PEL218 permit area. The flow stimulation of #1-Holdfast was undertaken in seven stages, targeting the primary target zones of the Roseneath shale (two stages), the Epsilon (three stages), and the Murteree shale (one stage), as well as a deeper secondary zone and the Patchawarra (one stage). During testing, hot water, steam and low levels of gas started to flow from the well during post-stimulation clean-up activities in July 2011. The gas flowrates have remained steady at around 1.8 million cu. ft. per day. Follow-up wells are planned to target the optimal producing zone identified by the extensive coring, stimulation, and testing program which has been undertaken by Beach in the Nappamerri Trough. According to Oil and Gas International, Beach's first shale gas exploration well in PEL218 was #1-Encounter, which was drilled east-southeast of #1-Holdfast. The #1-Encounter will be now undergo flow stimulation testing. Beach is the operator of PEL218 Permian Joint Venture with 90% interest in partnership with Adelaide Energy holding the remaining 10%.
