Kasawari (~5–10 TCF) — Estimated pre-drill CoS: ~15 – 30 %
Giant carbonate buildup: very high potential but moderate geological risk (seal and charge uncertainty, reservoir quality).
Operators usually assign mid-teens to low-30 % CoS for such large, partially delineated structures.
Lang Lebah (~5 TCF) — Estimated pre-drill CoS: ~10 – 30 % (likely around 15 – 25 %)
Central Luconia carbonate with similar challenges.
Attractive upside justified drilling despite moderate risk; typical pre-drill numbers for analogues fall in this range.
Marjoram (~2 TCF, part of Rosmari-Marjoram complex) — Estimated pre-drill CoS: ~15 – 35 %
Smaller structure, but by then subsurface knowledge and analog data in the area had improved, which usually lifts CoS somewhat compared to earlier wildcats.
