Amplitude Energy has announced that drilling has now commenced on the first East Coast Supply Project ('ECSP') well, with the Transocean Equinox rig spudding Elanora-1 on 25 January.
Elanora-1 is an exploration well located in permit VIC/L24 within Commonwealth waters, approximately 6km south-west from a tie-in point in the existing Casino, Henry, Netherby (CHN) pipeline.
Elanora-1 is targeting 161 Bcf in gross mean prospective resource from a Waarre A reservoir target (refer to table below and diagrams in appendix for further details) (1) . Amplitude Energy holds a 50% interest in VIC/L24 which contains the Elanora prospect, with the remaining 50% held by joint venture parter O.G. Energy
The estimated quantities of petroleum that may be potentially recovered by the application of future development project(s) relate to undiscovered accumulations. These estimates have both an associated risk of discovery and a risk of development. Further exploration, appraisal and evaluation is required to determine the existence of a significant quantity of potentially moveable hydrocarbons. The Elanora prospect is supported by high Waarre A reservoir amplitudes, which contribute to a probability of geological success of 67%(2) .
Forward plan
Further updates will be provided as drilling progresses through key milestones. Subject to operational conditions Elanora-1 is expected to take approximately 20-30 days to drill to a planned maximum total depth of up to around 2,000m True Vertical Depth Sub-Sea (TVDSS), with potential for approximately 4-7 further days of evaluation.
Following completion of the Elanora-1 program, the well will be plugged and a sidetrack into the Isabella prospect will be drilled, which is expected to take approximately 14-18 further days. Isabella lies immediately adjacent to Elanora, also in the VIC/L24 permit.
In the event of success in the sidetrack, evaluation of the discovery through logging will be conducted immediately to assess the gas composition and quality of the reservoir. The sidetrack is planned to be cased and completed with a sub-sea tree upon success, incorporating a flow test, and then suspended ready for development as part of the ECSP.
Managing Director and CEO Jane Norman commented that 'We’re excited to commence the drilling phase of the ECSP with Elanora-1. Elanora is the largest of our ECSP prospects, with a high chance of geological success2 , and a discovery at Elanora would provide us with a strong resource base for future tie-backs into our existing Otway Basin infrastructure. Recent exploration success from other parties in the Offshore Otway Basin reinforce our views on the ability of the basin to help supply the future energy needs of Australia’s East Coast domestic gas market.'
