Plattendolomit & Hauptdolomit Discoveries
Planned 3000ft horizontal well (41/24-3, 1992) drilled in a fault zone
• Only drilled 370ft AHL.
• Losses & kicks. Well killed 6 (six) times.
• “Gunk” – Diesel, bentonite & cement.
• Perfed only ~10% TVT of Plattendolomit.
Despite drilling issues, flowed 34mmscfgd & 1280bcpd
• Pressure decline was evident.
• DST reports by John Underwood (SRE), ERC & RPS all concluded a ~9.5Bcf connected GIIP.
The licence was relinquished.... but let’s relook at the geology....
Arenite & Europa awarded the block in late 2015.

Bunter in 41/24-3 is hydrostatic (RFT’s)

reportedly hydrostatic.
A ~5800ftss FWL yields an “apparent
overpressure” gradient of 0.71psi/ft to surface at top of Maxwell gasfield.
