Hole A
• APC/XCB to refusal (APC core orientation)
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI
Hole B

• RCB coring to 1249 mbsf
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI
Alternative: Hole A
• RCB to 1249 mbsf
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI

Anticipated lithology:
|
0–1249 mbsf: Terrigenous siltstone and silty mudstone with intervals of fine-grained sand and mud
