Drilling, coring, and downhole measurement program:
|
Hole A
• APC/XCB to refusal (APC core orientation)
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI
Hole B
• Drill without coring to APC refusal depth
• RCB coring to 1789 mbsf
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI
|
Anticipated lithology:
|
0–1605 mbsf: Terrigenous siltstone and silty mudstone with intervals of fine-grained sand and mud
1605 mbsf (or slightly shallower)–1789 mbsf: Limestone
