Proposed Site CRIS-13B

Priority: Primary
Position: 8°44.46177′N, 84° 6.81293′W
Water depth (m): 543
Target drilling depth (mbsf): 1430 (1330 m sediment, 100 m basement)
Approved maximum penetration (mbsf): 1430
Survey coverage: Inline 1209, Xline 2200
• Track map (Fig. AF1)
• Seismic profile (Fig. AF6)
• Location map (Fig. F6)
Objective: Characterize upper plate basement and fluid flow.
Drilling, coring, and downhole measurements program: • Hole A: APC/XCB to 600 mbsf.
• Hole B: drill without recovery to 590 mbsf, RCB from 590 to 1430 mbsf.
• Formation temperature measurements (APCT-3/SET).
• FlexIt core orientation measurements.
• Wireline logging (triple combo-UBI, FMS-sonic, VSI).
Nature of rock anticipated: Sediments: mud and silt, mud-supported breccia. Basement: shaly matrix breccia with carbonate, cherty, and basaltic clasts.
