Energy analysis: method, sources and rights
What was checked
Both selected table-4 rows match the existing CSV across all six quarters. HTTP delivery and the twelve figures were checked on 25 October 2026. The Global Energy Security Data supplement release is 12 August 2026. A later general STEO header is not treated as a new release date for this table.
What the source represents
Total oil is in million barrels per day; LNG is in billion cubic feet per day. These are estimated quarterly daily averages published by the EIA from Vortexa with additional EIA analysis. Its methodology dates cargo by chokepoint entry and estimates routes when AIS is incomplete. We assign no hours or timezone to a table without daily observations.
What we calculate
For each product: index = quarterly value ÷ 2025 Q4 value × 100. Change from A to B = (B ÷ A − 1) × 100. For quarter-to-quarter change, A is the immediately preceding quarter. The first change is blank because the preceding period is absent from this selection; it is not replaced by zero.
Principal calculations
Oil: (4.9 ÷ 21.6 − 1) × 100 = −77.31481481%. LNG: (0.8 ÷ 10.5 − 1) × 100 = −92.38095238%. Article values round to one decimal. Sensitivity replaces 2025 Q4 with 2025 Q1 as baseline: −76.55502392% and −93.16239316%.
Reproduction without private code
Download the CSV, check the six ordered rows and both units, then repeat the formulas without rounding intermediate inputs. Compare indices and changes with their columns, exported to eight decimal places for arithmetic convenience. The article displays one decimal. The published total-oil row is used directly rather than reconstructed from rounded component rows.
Visual rules
Absolute bars start at zero on separate product axes. Indices share a dimensionless scale and an explicit baseline, without a second axis or adding units. Each mark represents a quarter; connecting lines are not daily traffic observations or interpolations. Mobile variants, an accessible table and text alternatives are provided. No uncertainty bands are drawn when the table supplies none.
Original contribution and limits
The evidence matrix, calculated indices and changes, baseline sensitivity, visualisations and commercial-continuity interpretation are original. The matrix proposes evidence to seek; it does not claim that evidence was collected for any ship. We estimate no insurance premiums, consumption losses, causality, days blocked or future prices.
Rights checked and outstanding
The EIA general policy permits reuse of its products with attribution and date and requires translations and original contributions to be distinguished. It also excepts protected third-party materials. This table is credited to EIA analysis based on Vortexa: we use twelve already-published aggregate figures, not private tracking or AIS positions. We claim neither an open Vortexa licence nor independent legal clearance. Any additional third-party material needs its own permission check. No logos, photographs, third-party graphics or complete EIA/IMO texts are reproduced.
