Objective (see text for details):
|
Sample slope facies of progradational sequence boundaries, particularly Unconformities U4, U6–U9 (middle Miocene to early Pliocene), U11, and U13–U19 (Pliocene to Holocene) plus Marshall Paraconformity (if located above 1700 mbsf) (Oligocene)

Drilling, coring, and downhole measurement program:
|
Hole A
• APC/XCB to refusal (APC core orientation)
Hole B
• Drill without coring to APC refusal depth
• RCB coring to 1700 mbsf
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI
Hole C
• Drill without coring (tricone bit) to 800 mbsf
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI
|
Anticipated lithology:
|
0–1647 mbsf: Terrigenous siltstone and silty mudstone with intervals of fine-grained sand and mud
1647 mbsf (or slightly shallower)–1913 mbsf: Limestone
