Palm Valley 12 Drilling Update
Brisbane, June 14, 2022 AEST (ABN Newswire) - Central Petroleum Limited (
ASX:CTP) (C9J:FRA) (CNPTF:OTCMKTS) advises that on 13 June 2022, the Palm Valley 12 (PV12) well in OL3, Southwest of Alice Springs in the Northern Territory, was at a depth of 2,005m at 0600 hrs ACST in the P2 unit of the Pacoota Formation.
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.
