re: Pacific Tiger

The rig was skidded to the WBN4 location. WBN4 was spudded at 01:45 hours on Friday the 11th October and was at 224 m and reached the 9/58" casing TD at 03:45 hours at an average ROP of 282 m/hr. We are currently running the 9 5/8" casing.

WB-N4

Due to the WBN6 well result the target location of the next well WBN4 has been moved from the previous southerly location to an area approximately 250 m to the north of WBN6. The well will be drilled to confirm the continuity of the reservoirs encountered at WBN6. This will not only represent the northernmost step-out well drilled on the structure to date but also intercept the target reservoir at a greater angle than WBN6.
If successful, the well will prove-up the continuation of the primary target F-Sandstone and G-Sandstone reservoirs northwards over the Wichian Buri North structure and help to firm-up a potentially large exploitable area.

The proposed TD of the well is 1370 m ah (1002 m tvd) within Unit III of the Wichian Buri Group. Top F-Sandstone reservoir is predicted at m ah 1262 m ah (937 m tvd) and has a prognosed thickness of 35m. If the prospective G-Sandstone reservoir are encountered near the TD of the well then the well will be deepened accordingly.
