JA Daily Science Report for Expedition 309, 23 August 2005


LOCATION: Site 1256


SCIENCE UPDATE: The UBI logged up from 1219.6 mbsf with a repeat  interval as planned and was retrieved at 0400. The WST was made up and  worked down with drill water. The WST began taking weight at 274.6  mbsf and the tool was worked down to 374.6 mbsf. The WST was pulled back into the pipe and a second attempt was made to reenter in the open hole but the tool again began taking weight. The WST was pulled out of the hole resulting in the abandonment of the deployment.


The WST was on deck at 1315 and several kinks in the Schlumberger wireline were noted. The wireline was trimmed and a new head made up. It was decided to run the backup FMS due to the caliper problems with the initial deployment. The backup FMS was lowered to 1215.6 mbsf and logged up to 304.6 mbsf. After completion of the FMS pass a wireline heave compensator test was performed.
