Objective
(see text
for details):
|
Determine age of surfaces correlated with sequence
boundaries m1, m4, m5, m5.2, m5.4, m5.6, m5.8, m6,
and o1.
Determine facies of surfaces correlated with sequence
boundaries.
Determine paleobathymetry of surfaces correlated
with sequence boundaries.
Evaluate facies and age of Paleogene sediments.

measurement
program:
|
Push/rotary core to TD, cased as needed.
High-priority logging suite: total through-pipe
gamma
ray, induction resistivity, sonic measurements,
magnetic susceptibility, open-hole spectral and total
gamma ray, mechanical caliper, vertical seismic
profiling, in situ

and shell fragments, sandy mudstone, mudstone,
marly
chalk, limestone.
