Emperor Energy Ltd., Sydney, commenced a pre-front end engineering design (pre-FEED) stage for development of its 100%-owned Judith gas-condensate field in offshore Gippsland basin permit Vic/P47 in Victoria.
The pre-FEED study comprises early design concepts for a gas processing plant to operate adjacent to and in parallel with the existing Orbost plant that is currently processing gas from Cooper Energy’s Sole gas.
There will also be initial design for a 40-km long subsea pipeline from the field to a shoreline crossing along with an export pipeline from the shore plant to the Eastern Gas Pipeline that carries gas up the east coast to Sydney.
In addition, the study will refine indicative project cost estimates and project scheduling.
Emperor said the pre-FEED work, which is being done by the APA Group, will take about 4 months to complete.
The design basis is for production and processing of 80 million cu ft/day of gas (90 terajoules/day) across a projected 25-year project life.
The pre-FEED stage follows a memorandum of understanding between Emperor and APA for Judith field signed in October 2019.
Emperor has also revised the field production well stimulation model to include four vertical production wells at the beginning of the project with a fifth production well added in the 15th year.
Initial well design for the proposed Judith-2 appraisal-exploration well has also been completed. Emperor said negotiations for a suitable drilling rig will commence once a farm-in partner has been secured. Potential farminees are currently assessing field data.
Emperor estimates contingent 2C resources at the field of 150 bcf along with 2.2 million bbl of condensate.
