• Track map (Fig. AF1)
• Seismic profile (Fig. AF4)
• Location map (Fig. F3)
Objective (see text for details):
Sample facies landward of clinoform breakpoints of progradational sequence boundaries, particularly Unconformities U6–U19 and slopes of Unconformities U4–U5 (middle Miocene to Pliocene)
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 976 mbsf
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI
Alternative: Hole A
• RCB to 976 mbsf
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI
Anticipated lithology:
0–976 mbsf: Terrigenous siltstone and silty mudstone with intervals of fine-grained sand and mud
