Chikabi

Nihon Chika Sekiyu Bichiku Co., Ltd. (日本地下石油備蓄株式会社 / Chikabi Co., Ltd.) — Subsurface (rock-cavern) strategic crude stockpile operating dataset from three Japanese national petroleum stockpile bases — Kuji (Iwate), Kikuma (Ehime) and Kushikino (Kagoshima), ~1.75 million kL each. The central instrument room's operations-management system continuously logs crude receipt through discharge, weather and sea-state data collection, safety/disaster systems and environmental-treatment plant status. Layered on top are decades of integrity monitoring records: daily and periodic facility inspections, rock…

Chikabi offers (Alternative, Supply Chain, Geospatial, Reference) — Total monitored capacity 5.25 million kL across three bases (1.75 million kL each, held in rock-cavern units of 2+4, 3 and 3 units respectively). Continuous supervisory telemetry from three 24/7 instrument rooms plus a distributed groundwater-well network gives order 10^7-10^8 sensor readings over the operating life, with inspection and survey records in the tens of thousands. Estimate from disclosed capacity, unit and well-network structure; no counts are published..

Underground storage integrity and leakage model training for cavern-type fuel or gas storage (a scarce labelled dataset — few operators worldwide run instrumented rock-cavern storage at this scale); geotechnical and seismic performance benchmarking for buried energy infrastructure; energy-supply and reserve-release modelling, since the observable inventory behaviour of three national bases is a direct input to Japanese crude supply analysis; insurance and catastrophe modelling for underground hydrocarbon storage; siting and permitting feasibility models for new underground storage or hydrogen/natural-gas cavern projects, which need real rock-mass and groundwater baselines.

The data is with 33 years of history.

Coverage spans Japan; Oil & Gas Storage & Transportation, Petroleum Refining and Marketing; alternative, supply_chain, geospatial, reference; commodities, equities.
