Project Overview of the 2023–2024 Production Test of Gas Hydrate on the Alaska North Slope

Abstract A 10-month gas production test from a gas hydrate-bearing sand reservoir was successfully conducted on the Alaska North Slope to better understand reservoir depressurization-based gas production. The JOGMEC-DOE-USGS Collaborative Gas Hydrate R&D Project in Alaska was imp...

Integration of high-κ oxide on 2D semiconductors with carbon-dot monolayer assembly as van der Waals interfacial layer

The atomically smooth surfaces of two-dimensional (2D) nanomaterials minimise scattering-induced carrier-transport degradation. However, this same attribute poses a major challenge for integrating 2D materials with high-quality dielectrics at sub-nanometre equivalent oxide thickn...

Measuring Fluid Flow and Tracking Bio-Mediated Precipitation in Propped Shale Fractures

Abstract Hydraulic fracturing has enabled the extraction of oil and gas from ultra-low permeability shale formations by creating propped fractures that serve as primary fluid flow conduits. While numerical models have advanced understanding of fluid flow through these fractures,...

Multiphysical Responses of a Gas Hydrate Reservoir to Extended-Duration Gas Production on the Alaska North Slope

Abstract The field test of extended-duration gas production from a gas hydrate-bearing reservoir via depressurization─formally titled the JOGMEC–DOE–USGS Collaborative Gas Hydrate R&D Project in Alaska─was conducted in the Prudhoe Bay Unit on the Alaska North Slope during 2023–20...

Alaska North Slope HYDRATE 02 Geo Data Well (GDW) Downhole Logging, Pressure Coring, and Completion Operations and Data

Abstract The “Collaborative Gas Hydrate R&D Project in Alaska,” led by the Japan Organization for Metals and Energy Security (JOGMEC), the U.S. Department of Energy (DOE), and the U.S. Geological Survey, aims to examine and assess gas hydrate reservoir systems, their production b...

Overview of the Monitoring Program in the Alaska North Slope Extended-Duration Gas Production Test from Gas Hydrate

Abstract As a part of an extended-duration gas production test conducted under the JOGMEC-DOE-USGS Collaborative Gas Hydrate R&D Project in Alaska, one of the main objectives was to understand the behavior of gas hydrate formation and the production system during long-term depres...

Operational Overview of the JOGMEC-DOE-USGS Gas Production Test from Gas Hydrate on the Alaska North Slope

Abstract To understand the long-term production behavior of gas hydrate, an extended-duration gas production test was conducted under the JOGMEC-DOE-USGS Collaborative Gas Hydrate R&D Project in Alaska. The production test began in September 2023 using an electric submersible pum...

From Trace Element Biogeochemistry to Critical Minerals Resourcing: Lessons Learned and Opportunities for Innovation

Abstract Critical minerals and materials, which are raw materials essential to modern technologies yet vulnerable to supply disruption, have emerged as a major focal point of research to diversify resources, advance processing technologies, and bolster supply chains. Many of thes...

Geological & Petrophysical Findings from Production Test Wells of Gas Hydrate Reservoirs at the Kuparuk State 7–11–12 Site in the Prudhoe Bay Unit on the Alaska North Slope

Abstract As part of a long-term production test targeting gas hydrate reservoirs at the Kuparuk State 7–11–12 site in the Prudhoe Bay Unit on the Alaska North Slope, two production wells (PTW-1 and PTW-2) and one monitoring well (GDW) were drilled in 2023. This study advances res...

Alaska North Slope HYDRATE 02 Geo Data Well Multicomponent Inversion and NMR Log and Core Analysis of the B1 Sand Gas Hydrate Reservoir

Abstract The Collaborative Gas Hydrate R&D Project in Alaska, a joint initiative by the Japan Organization for Metals and Energy Security, the U.S. Department of Energy, and the U.S. Geological Survey, aims to advance understanding of gas hydrate reservoir systems and their produ...

Characterizing Physical Properties and Controls on Gas Hydrate Saturation Using Borehole Log and Core Data at the Alaska North Slope Gas Hydrate Production Test Site

Abstract The JOGMEC-DOE-USGS Collaborative Gas Hydrate R&D Project in Alaska has acquired a wealth of geophysical data at the Kuparuk State 7-11-12 site on the Alaska North Slope to facilitate site characterization and interpretation of the 2023–2024 extended duration reservoir r...

Near-Adjacent HeavyLanthanide Separation and SensingUsing Dimerizing Lanmodulins

Abstract Protein-based recovery, detection, and separation of rare earth elements (REs) have accelerated since the discovery of the lanmodulin (LanM) proteins. While exceptional at total RE recovery, prior proteins, like most ligands, exhibited limited ability to differentiate RE...
