PERTH, Australia – Carnarvon Energy has supplied an update on the FEED for the Santos-operated project offshore Western Australia.
Detailed design and engineering work for the Dorado Phase 1 liquids development is progressing, with facilities engineering and subsurface studies confirming initial deliverability of 75,000–100,000 b/s of oil.
Studies also show that the associated gas can effectively be re-injected into the Dorado reservoirs to maintain reservoir pressure, sustaining strong production rates.
This gas will also be available for production under the subsequent, Phase 2 development, and has been incorporated in the basis of design for the facilities.
Detailed design has finished for the production and injection wells, with tenders issued for long lead items. A final capital cost definition, part of the FEED process, will be completed ahead of a Final Investment Decision (FID).
Since Dorado is in shallow water, close to existing infrastructure and is an industry-standard design (according to Carnarvon), initial estimates suggest this will be a relatively low unit cost operation.
Applications for regulatory approvals are with the regulators for assessment, with the Production License set to be granted ahead of FID (expected around mid-year).
