Slightly elevated Sw indicated by
Ben/Tol, possibly sensing deeper
shows. Minor bit generated gas
suggested by hydrogen
SHOW: C1-C4 above OBM baseline.
Helium indicates FG and follows
porosity. Gas ratios suggest
productive wet gas. No significant
CO2. Continued minor component
of bit gas

SHOW #1

Possible compartment boundary
Further increase in Ben/Tol
suggests elevated Sw zone in
communication with show below
SHOW: C1-C8 above OBM baseline.
Helium indicates FG and follows
porosity. Gas ratios suggest
producible wet gas to gas
condensate. Presence of norm-C7,
aromatics and reported
fluorescence indicates presence of
liquids. Trace CO2. Compartment
boundaries at 8790 ft and 8810 ft.
Base of show at 8828 ft indicated
by heavy/light hydrocarbon ratios.

POOH for new BHA
SHOW: C1-C9 above OBM baseline.
Helium suggests better porosity
than above. Gas ratios suggest
producible wet gas to gas
condensate. Presence of norm-C7,
aromatics and reported
fluorescence indicates presence of
liquids. Trace CO2. Base of show
at 8960 ft indicated by heavy/light
hydrocarbon ratios.
