Sepalosiphon

Proposed TD: 3,150 m ss

Sepalosiphon is a fault-bounded, north-south elongated, easterly plunging faulted anticline, adjacent to, and at approximately the same subsurface depth as, the Stanley-1 gas discovery. The southern bounding fault of the structure is a southerly vergent reverse fault with small magnitude displacement that separates it from Stanley. The northern two-thirds of the feature, including the culmination, are in PPL 269, with the southern one-third of the prospect in PRL 4. The feature is defined on the broad regional seismic grid that extends from the southern edge of PPL 269 south and east, tieing to the gas discoveries at Stanley-1, Ketu-1 and Elevala-1.

Stanley-1 found 7.8 m net, 13.5 m gross pay at the top of a 35 m gross Toro interval that includes 28.5 m of reservoir quality sand. The GWC was encountered at 3137.5 m BKB. Alternative correlations between local gas gradients and condensate yields suggest a condensate yield of either 25 or 34 STB/MMSCF.

Sepalosiphon is expected to encounter a Toro reservoir similar to that in Stanley-1. The prospect occupies a similar location to Stanley-1 with respect to charge from the Cecilia and Kau Troughs. Our prospect volumetrics are as follows:
