Pressure Core Measurements of Sediment Properties from Krishna-Godavari Basin

Junbong Jang of the United States Geological Survey released data from pressure core measurements of fine-grained seal sediment from the Krishna-Godavari Basin offshore eastern India. The dataset provides results for flow-through permeability, consolidation, and direct shear measurements collected during the 2015 Indian National Gas Hydrate Program Expedition 2 (NGHP-02). This data is used to understand sediment properties relevant to methane extraction from gas hydrate reservoirs.

Use Cases

• Model reservoir depressurization efficiency based on seal sediment permeability measurements.
• Assess gas hydrate reservoir stability based on sediment shear strength measurements.
• Calibrate geomechanical models using sediment compressibility data from consolidation tests.

Strengths

• Data originates from a specific, documented scientific expedition (NGHP-02, 2015).
• Measurements are focused on three key physical properties for reservoir engineering: permeability, compressibility, and shear strength.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
