In 2017, the Gulf of Mexico Hydrate Pressure Coring Expedition (UT-GOM2-1) drilled and cored a hydrate-bearing channel-levee system in Green Canyon Block 955 (GC 955) in the Gulf of Mexico. This was the first scientific expedition offshore United States focused on recovering cores at in situ pressure within high-saturation hydrate reservoirs. The initial scientific results from this expedition were published in the AAPG Bulletin v. 104, no. 9 (Boswell et al., 2020). In that volume, seven papers describe the overall effort (Flemings et al., 2020), the role of salt diapirism on the temperature and pressure of the hydrate system (Portnov et al., 2020), the pressure coring (Thomas et al., 2020), the sedimentology and stratigraphy (Meazell et al., 2020; Santra et al., 2020), the hydrate saturation and chemistry of the gas present (Phillips et al., 2020), and initial estimates of reservoir porosity and permeability from reconstituted samples (Fang et al., 2020). This second dedicated volume arrives 5 yr after the UT-GOM2-1 Expedition and describes further geophysical interpretation, modeling, and laboratory analysis using pressure cores and gas samples from GC 955. Nine papers are divided into three themes that range from the basin scale to the pore scale: (1) the gas hydrate system (Moore et al., 2022, this issue; Santra et al., 2022, this issue; Wei et al., 2022, this issue); (2) depressurization (Phillips et al., 2022, this issue); (3) petrophysics and geomechanics (Daigle et al., 2022, this issue; Fang et al., 2022a, b, this issue; Oti et al., 2022, this issue; Yoneda et al., 2022, this issue). We review these contributions to the AAPG Bulletin v. 106, and discuss the new insights gained at GC 955 from these contributions. Moreover, we identify how these contributions fit into broader scientific knowledge and emphasize remaining challenges in the evaluation of natural gas hydrate systems.
