ASX AND MEDIA ANNOUNCEMENT
21 February 2013
DRILLING REPORT FOR CYRENE-1 IN EP 438, CANNING BASIN, WESTERN AUSTRALIA
FOR THE PERIOD 0600 HOURS 12 FEBRUARY 2013 TO 0600 HOURS 21 FEBRUARY 2013
Since the last report issued at 0600 hrs 12 February 2013, DCA Rig 7 has completed all coring and logging of
the Goldwyer Formation to 1022m RT (rotary table). The 7” casing required to isolate the Goldwyer and other
formations in the 8 ½” hole have now been run in the hole and cemented.
The completion of coring in 8 ½”corresponded with consistent oil shows across the lower Goldwyer Formation
and background gas up to 5 units in the lower part of the Goldwyer. These results are consistent with the
drilling of the Goldwyer to date, indicating that the Goldwyer Formation is a good source rock for generating
oil in this part of the Canning Basin.
All necessary BOP testing to drill ahead in the 6” hole section were completed and drilling has now been
completed into the Willara Formation conventional oil objective with total depth (TD) called at 1070m RT.
Background gas was observed to be between 5 and 10 units with some oil shows observed through the
Willara sequence. The forward plan is to run wireline logs and then conduct a drill stem test in the 6” hole to
fully evaluate the Willara Formation. The purpose of the flow test is to establish the true formation fluid in the
Willara Formation (water or oil) and if any hydrocarbons are present, whether they can flow at economic
rates.
The next ASX release will be made when the Willara Objective has been fully evaluated or if there is a material
event to report.
