Drilling and coring program:
|
• Hole A: APC to ~200 mbsf with non-magnetic core barrels and core orientation
• Hole B: APC to ~200 mbsf with non-magnetic core barrels
• Hole C: APC to ~200 mbsf with non-magnetic core barrels
• Hole D: APC/XCB to 986 mbsf
• See Drilling and coring strategy and Table T3

• Hole A: APCT-3 (SET if needed) formation temperature measurements
• Hole D: wireline logging with triple combo, FMS-sonic, VSI, and Magnetic Properties tool strings
• See Downhole measurements strategy and Table T3
