Site: HR5a
Position: 44.586096°N, 125.093815°W
Target Drilling Depth: 260 mbsf
Approved Maximum Penetration: 260 mbsf
Seismic Coverage: TTN112 3-D high-resolution seismic survey
Objectives: To constrain the timing of formation of this anticline, the nature of the sediments that host an anomalously strong BSR beneath it, and the nature of reflection C in the uplifted basin to the west.
Drilling Program: APC to refusal, XCB to refusal. Use of PCS and/or HYACE.
Logging and Downhole Program: LWD, triple combo, APC-temperature, DVTP, APC methane tools.
Nature of Rock Anticipated: Interlayered silts and clays, some authigenic carbonates possible, highly deformed accretionary complex sediments.
