The University of Texas Hydrate Pressure Coring Expedition (UT-GOM2-1) recovered cores at near in situ formation pressures from a gas hydrate reservoir composed sandy silt and clayey beds Green Canyon Block 955 the deep-water Gulf Mexico. expedition results are synthesized linked to other detailed analyses presented this volume. Millimeter- meter-scale interbedded on levee turbidite channel. saturation (the volume fraction pore space occupied by hydrate) silts ranges 79% 93%, there is little...
We interpret the sedimentologic evolution of a deep-water channel-levee deposit in Green Canyon Block 955 (deep-water Gulf Mexico) by analyzing hydrate-bearing pressure cores and nonpressure collected during The University Texas-Gulf Mexico 2-1 (UT-GOM2-1) Hydrate Pressure Coring Expedition that preserve remarkable sedimentary structures. levee is composed alternating beds sandy silt clayey range from millimeters to meters thickness. each couplet records single turbidity current flow which...
Gas hydrate in the Green Canyon area (Block 955) northern Gulf of Mexico is hosted by relatively clay-free silty levee deposits bounding a Pleistocene submarine channel. During initial phase channel development, axis experienced sediment bypass while to sandy flanking levees formed. Development high prompted gravitational collapse along normal faults dipping toward axis. Extension at was accompanied compression The failure caused rotation and displacement deposits. Later, deposition occurred...
The base of the gas hydrate stability zone (GHSZ) is a critical interface, providing first-order estimate distribution.Sensitivity to thermobaric conditions makes its prediction challenging particularly in regions with dynamic pressure-temperature regime.In Green Canyon northern Gulf Mexico (Block GC955), seismically inferred GHSZ 450 meters (1476 ft) below seafloor, which 400 m (1312 shallower than predicted by modeling using standard temperature and pressure gradient assumptions, an...
In May 2017, The University of Texas Hydrate Pressure Coring Expedition Gulf Mexico 2-1 (UT-GOM2-1) drilled two adjacent holes in Green Canyon Block 955 the deep-water as part at Austin and US Department Energy Deepwater Methane Characterization Scientific Assessment. operations included testing configurations a rotary pressure-coring tool gas hydrate–bearing formation. first hole, an extended core barrel (cutting shoe) configuration Tool with Ball Valve (PCTB-CS) was deployed, second PCTB...
Abstract We present a systematic model that links the generation, migration, phase partitioning, and accumulation of methane into closed loop as sediment is deposited from seafloor buried through base hydrate stability zone (BHSZ). In our model, generated by biodegradation organic carbon in muds. Hydrate does not form trapped until coarse‐grained layer deposited, because small pores prevent formation Instead, diffuses sands/silts where solidifies hydrate. As hydrate‐bearing pass BHSZ during...
Abstract We present a geological and geotechnical assessment of the outer continental shelf (OCS) northern Gulf Mexico, relevant to prospective offshore wind energy developers for identifying geohazards developing reconnaissance level understanding foundation zone conditions. The information provided in this paper is considered helpful designing appropriate geophysical site investigation campaigns, preliminary evaluations suitability various concepts infrastructure during planning stage...
