 Focused in Area 4 and Area 9 :
Here are the list of wells in area 4: development wells of Scarab wells (8 wells), serpent wells (3 wells), Saffron Dj, and Sparrow-1.
Here are the list of wells in area 9: development wells of Sequoia wells (5 wells), Saurus wells (2 wells), Sapphire Da, Sapphire Db, and Libra-Da .

 Scarab-De1a :
- There is no gas sand missed in this well ,Ch-1 and Ch-2 (Scarab Ch )
completed as open hole.

 Scarab-Dd :
- There is no gas sand missed in this well ,Ch-1 and Ch-2 (Scarab Ch )
completed as open hole.

 Scarab-Dq :
 Ch-11 completed open hole.
 Ch-17 not completed in this well because the LWD
(Testrak) pressure measurements indicate that Channel
11 and Channel 17 are on separate pressure trends.
 The pressure data in the previously un-developed
Channel 17 shows a reservoir with 2 thin gas zones and
2 likely perched water zones and insufficient stand-off
from water to consider its development.
