Dorado-1 Drilling Update
The well has been drilled in a 17-1/2" hole to 1,162 metres Measured Depth ("MD") and the 13-3/8" casing has been set.
Drilling of the 12-1/4" hole has commenced with current drilling operations at approximately 1,250 metres MD.
Drill the 12-1/4" hole section to planned depth of approximately 3,600 metres MD. Following this, a 9-5/8" casing will be set before the 8-1/2" hole section is drilled to the top of the primary Caley Member section, which is expected to be intersected at a depth of approximately 3,800 metres MD.
The primary objective for the Dorado-1 well is to assess the gas and liquids potential in the Caley Member with the well being less than 20km from and updip of the successful Roc-1 and Roc-2 wells.
The Dorado structure at the Caley interval is estimated to contain a gross mean recoverable prospective resource of 545 Bscf of gas and 30 million barrels of associated condensate (being 125 million barrels of oil equivalent ("boe"), gross, Pmean). Multiple secondary targets have been identified by Carnarvon in the Crispin and Milne Members (see Figure 4 in link below) and these will also be assessed by the Dorado-1 exploration well. See the recently released volumetric strategy update (ASX 23 April 2018) for details on these targets.
Prospective Resources are the estimated quantities of petroleum that may potentially be recovered by the application of a future development project and may relate to undiscovered accumulations. These prospective resource estimates have an associated risk of discovery and risk of development. Further exploration and appraisal is required to determine the existence of a significant quantity of potentially moveable hydrocarbons.
