Scientific Purpose/Goals: Scientific purpose is summarized from the cruise overview available at: http://www-udc.ig.utexas.edu/gom2/Chapter%201%20-%20Expedition-Summary.pdf The underlying goal of the UT-GOM2-1effort was to increase our understanding of the production potential of hydrate-bearing sands. Logging while drilling has documented the occurrence and estimated the concentration of hydrate-bearing sands in the Gulf of America (Gulf of Mexico). To better understand the production potential of these reservoirs, samples need to be recovered and petrophysical analyses performed. We wish to illuminate questions that range from what is the compressibility and permeability of both the reservoir and its bounding units to what is the concentration and chemistry of the hydrate and the pore water.

Notes: The GOM2 project was supported by the Department of Energy, with the University of Texas as the science lead. Pressure cores were acquired through a gas hydrate-bearing reservoir in the Green Canyon 955 (GC955) lease block in the northern Gulf of America (Gulf of Mexico). Through our partnership with U. Texas, we were given two pressure cores to analyze with the Pressure Core Characterization Tools at the USGS in Woods Hole.
Stephen Phillips was a shipboard scientist for the GOM2 project, working with the U. Texas prior to working for the USGS. He, along with William Waite (USGS) are affiliated with several papers published in special journal volumes by the AAPG. Those papers published by Waite, or by Phillips (after beginning work at the USGS) will be linked with this FAN. The complete set of papers can be downloaded from AAPG:

The University of Texas also hosts a site with the cruise reports, shipboard data, and links to various publications:
