Weekly US natural gas underground storage intelligence from the U.S. Energy Information Administration's Natural Gas Navigator (keyless XLS downloads): the Lower 48 total plus the five EIA storage regions (East, Midwest, Mountain, Pacific, South Central), working gas in billion cubic feet, weeks ending Friday, 2010 -> present. Per entity x week: working gas, week-over-week net change (injections positive), year-over-year change vs the same EIA week, the trailing 5-year seasonal average for that week and the deviation from it in BCF and percent, a documented 0-100 storage-pressure score with per-week ranks, injection/withdrawal/below-average/record flags, and a heating-season marker. EIA content is U.S. federal public domain (commercial reuse allowed); source: U.S. Energy Information Administration.

Column	Type	Description
week	string	Reference week: the Friday week-ending date of the EIA weekly storage report, ISO date. (unit: ISO date (Friday))
country_code	string	ISO alpha-3 country code (USA for every row). (unit: ISO 3166-1 alpha-3)
entity_code	string	Stable entity key: L48 (Lower 48 states), EAST, MIDW (Midwest), SCEN (South Central), MTN (Mountain), PAC (Pacific). Primary join key with week. (unit: code)
entity_label	string	Human-readable entity name: 'Lower 48 states' or the EIA storage region name.
entity_type	string	Entity kind: national (Lower 48) or region. (unit: categorical)
working_gas_bcf	float	Working natural gas in underground storage as published by EIA. Null only where upstream publishes no value (never zero-filled). (unit: billion cubic feet)
wow_bcf	float	Week-over-week net change in working gas: positive = net injection, negative = net withdrawal. (unit: billion cubic feet)
wow_pct	float	Week-over-week percent change in working gas. (unit: percent)
yoy_bcf	float	Change vs the same EIA week one year earlier on the Friday grid. Null for the first 52 weeks of each entity (warm-up). (unit: billion cubic feet)
yoy_pct	float	Percent change vs the same EIA week one year earlier. Null for the first 52 weeks of each entity (warm-up). (unit: percent)
avg_5yr_bcf	float	Trailing 5-year seasonal average of working gas for that calendar week (EIA's own benchmark); requires at least 3 of the 5 prior years non-null. (unit: billion cubic feet)
dev_vs_5yr_bcf	float	Working gas minus the trailing 5-year seasonal average for that week. (unit: billion cubic feet)
dev_vs_5yr_pct	float	Deviation from the trailing 5-year seasonal average as a percent of the average. (unit: percent)
tightness_pct	float	How far below the 5-year seasonal average the entity sits (= -dev_vs_5yr_pct). Positive = tighter than normal for the season. (unit: percent)
storage_pressure_score	float	Documented 0-100 composite, per week, across the 6 entities: 100 * (0.6 * min-max(clip(tightness_pct, -15, +15)) + 0.4 * min-max(clip(-wow_pct, -3, +3))). High = storage is tight vs the seasonal norm and gas is being drawn down. Degenerate weeks score 50. (unit: 0-100 score)
pressure_rank	integer	Per-week dense rank of storage_pressure_score across the 6 entities, 1 = tightest. (unit: rank)
pressure_tier	string	Tier of storage_pressure_score: t1 hot (>= 75), t2 (50-75), t3 (25-50), t4 comfortable (< 25). (unit: categorical)
injection_flag	float	1 when wow_bcf is positive (net injection week). (unit: binary)
withdrawal_flag	float	1 when wow_bcf is negative (net withdrawal week). (unit: binary)
below_avg_flag	float	1 when working gas is below the trailing 5-year seasonal average for that week. (unit: binary)
record_high_52w_flag	float	1 when working gas equals the trailing-52-week maximum (inclusive). Null until 52 weeks of history exist or where working gas is null. (unit: binary)
record_low_52w_flag	float	1 when working gas equals the trailing-52-week minimum (inclusive). Null until 52 weeks of history exist or where working gas is null. (unit: binary)
heating_season_flag	integer	1 when the week falls in November-March (the heating season, when withdrawals dominate). (unit: binary)
as_of	string	Latest reference week in the fetched panel (YYYY-MM-DD); identical across rows and across runs on the same vintage. (unit: ISO date)
source_series	string	Stable public EIA series code (e.g. NW2_EPG0_SWO_R31_BCF) the row was parsed from. (unit: code)
row_hash	string	Deterministic 16-hex row id: sha256('GASSTOR\|<entity_code>\|<week>'). (unit: hash)
