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

Drilling,
coring, and
downhole
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
borehole temperature.
Low-priority logging suite: hydrogeological properties,
acoustic imaging (including acoustic caliper).
VSP survey will be attempted if VSP is unsuccessful
at Sites MAT-1 and MAT-2.

Anticipated
lithology:
|
Sediments: medium to coarse sand, possible pebbles
and shell fragments, sandy mudstone, mudstone.
Basement: not reached.
