Palm Valley 12 Drilling Update
The P2 unit of the Pacoota Formation is the seal for the P3 reservoir zone in the Palm Valley field and is a key casing point for drilling the deeper Arumbera exploration target.
Activity this week has been focused on cementing the 9 5/8" casing string in the fractured formation. This has proved problematic, with losses continuing whilst pumping cement.
Intermittent returns to surface indicate that cement was being pushed into significant fractures within the formation.
Several remedial cement plugs have been run to help strengthen the seal around the casing shoe. The plan is to continue running cement plugs until the required kick tolerance at the shoe has been achieved. At that point, drilling will resume in the 8 1/2" hole section.
The PV12 well has two alternate objectives. The primary deep gas exploration target is the Arumbera Sandstone at an anticipated depth of 3,560m. Alternatively, if the deep exploration target is not successful, a shallower gas appraisal lateral will be drilled in the currently producing P1 formation with the potential to become a production well.
The PV12 well is the first of a 2-well drilling program that also includes the Dingo-5 exploration / production well. Both wells are being drilled under joint ventures between Central (50% interest), New Zealand Oil & Gas Limited (ASX:NZO) (35% interest) and Cue Energy Resources Limited (ASX:CUE) (15% interest) and are scheduled to be completed this year.
