Petroleum terminal wholesale balance and transfer records for AI
A terminal stock summary and transfer record can use different times or quantity bases.
NAICS 424710 · Petroleum Bulk Stations and Terminals
A terminal stock summary and transfer record can use different times or quantity bases. EIA explains petroleum stock reporting. An original exercise can test balance reconstruction without exposing any live facility or operational records. EIA petroleum stocks definitions
Invent an opening balance, a documented receipt and a later outbound transfer. Put one adjustment after the reporting cutoff. Ask which entries affect the stated closing balance and where the unit basis is missing. A reviewer checks arithmetic and the cutoff. Include a transfer acknowledged by the sender only, so the model must preserve a pending receiving state alongside the balance calculation.
Use abstract products and fabricated numbers. Exclude real inventory, facility diagrams, transport schedules, customer records and operating procedures.
Describe a synthetic terminal balance exercise
Original Fiund exercise
A sender-side balance can reconcile while the destination receipt remains pending
A wholly fictional terminal ledger uses abstract product labels and arbitrary quantity units. It contains no real stock, facility, schedule, customer or operating procedure.
| Record | Source | What it records |
|---|---|---|
| TTB1 | Opening and inbound | Day D reference basis U: opening 100, matched received addition 20 before 12:00 cutoff. |
| TTB2 | Outbound event | Before cutoff, sender ledger posts 15 U dispatched. Original balance rule subtracts posted dispatches; recipient acknowledgment absent. |
| TTB3 | Later adjustments | Approved +5 U effective 13:00, after cutoff. Loose +2 record before cutoff has no unit or reviewed posting authority. |
Question for the model
What closing sender balance follows at 12:00, and what evidence remains missing for the transfer and loose adjustment?
Show the reference answer and checks
TTB1 and TTB2 yield 100 plus 20 minus 15, or 105 U in the fictional sender ledger at noon. The dispatched 15 is posted there but lacks destination acknowledgment. TTB3's approved five applies after the cutoff, and the loose two lacks unit and posting support, so neither enters the noon balance. Preserve the arithmetic basis and pending receiver state independently rather than treat reconciliation as completed cross-party transfer.
- Including a post-cutoff adjustment or a quantity with unknown unit.
- Treating a sender-side dispatch posting as confirmed recipient receipt.
Fields to preserve
- Ledger basis and cutoff
- Defines the snapshot.
- Posted receipt, dispatch and effective adjustment
- Supports arithmetic.
- Recipient acknowledgment and missing unit
- Preserves separate gaps.
Test another case
Ask for a 14:00 sender snapshot while the receipt stays pending. Require 110 U on the stated basis without closing recipient custody.
Use original synthetic balances and no live system. Exclude real inventory and facility information; authorized staff retain all operational decisions.
