May 16  - Keathley Canyon 151 - Logging and Coring

Location: Keathley Canyon 151#3

Science Update - May 16:
Fugro Pressure Core (18P) collected a core but it was not under pressure due to a broken liner. Cores 19H and 20H were 8-m FHPC cores that retained gas voids and permitted gas sampling. Core 21H appeared to have reached the penetration limit for the hydraulic piston core, recovering only about 2.5-m of core. Core 22C was a 3-m core obtained with the Fugro Corer. None of these cores had cold spots when imaged by the IR camera, although cores 19H and 20H had significant gas expansion.

Plans:
Continue drilling down with coring every second pipe joint down to 380 mbsf. At 380 mbsf, start continuously coring through the depth corresponding to the seismic BSR (385 mbsf) to 405 mbsf, with pressure cores above and below the depth of the BSR.
