The National Methane Hydrates R&D Program
The DOE/JIP Gulf of Mexico Hydrate Research Cruise
During this expedition we will maintain a log of information relayed from the chief Scientist on the expedition. Whenever possible, images will be displayed along with the text.

Working with Push Cores from AT14 - #1 |
Science Update: Logging Scientist has provided the science party with a preliminary interpretation of the LWD results from AT14#1. The caliper log shows good to very good hole conditions, with some breakouts or washouts in the deeper part of the hole. The gamma-ray log indicates clay-dominated muds with no sands. Porosities from density are high, with no consistent trends. Resistivity logs are very good, with no obvious indications of gas hydrates. There is a shift to lower resistivity values at the approximate depth (200 mbsf) of the penetration of the side of the diapiric feature underlying Mound F near AT14#1. This could indicate low concentrations disseminated gas hydrate or free gas.
Plans: First Fugro Hydraulic Piston Corer (FHPC) core is expected tomorrow AM. Making final preparations to receive, process, sample and store cores.
