INDUSTRY FIELD GUIDE
Refinery data for AI stream and sampling-period review
Petroleum-refinery records can concern a process stream, a tank inventory or a finished dispatch.
NAICS 324110 · Petroleum Refineries
Petroleum-refinery records can concern a process stream, a tank inventory or a finished dispatch. The Census manual defines the industry scope. An original AI exercise can test whether an assistant keeps those record contexts attached to the right sample. Census refinery industry scope
Create fictional stream labels, a tank-transfer ledger and laboratory reports with explicit sampling times. Give two reports the same broad product name but different sampling points. Ask which evidence concerns a selected dispatch. Include a tank carryover with a known quantity but an absent source reference. The review key should preserve that unresolved contribution instead of assigning the entire dispatch to the newest transfer.
Annotate stream, tank, sample, time interval, measurement basis and report version. Hold out a new identifier scheme for evaluation. Score wrong-stage substitution, unsupported tank continuity and use of an outdated report separately. A response should cite the source field supporting each accepted relationship and identify a complete match when the required records are available.
Use self-authored tables and invented measurements for a pilot. Actual operating conditions, blend instructions, customer contracts and outside laboratory reports require disclosure authority. A licensing proposal should identify the evidence-selection task and qualified reviewer key. Confirm the buyer's required material and source history before preparing an operating archive or commissioning additional capture.

Original Fiund exercise
A sample belongs to its collection window
An inert table exercise represents fictional refinery streams with plain identifiers, no chemistry or operating instructions.
| Record | Source | What it records |
|---|---|---|
| 1 | Transfer log | Tank T receives stream A until 11:00 and stream B from 11:00. |
| 2 | Sample ticket | Jar Q taken at the inlet at 10:55, logged at 11:20. |
| 3 | Lab index | Report Q1 references jar Q; timestamp 14:10 is report publication. |
Question for the model
Which stream label belongs on Q1?
Show the reference answer and checks
Use stream A: record 2 places collection at 10:55 at the inlet, before the transfer boundary in record 1. Neither the 11:20 registration nor report publication at 14:10 changes the sampled stream. The exercise does not identify the tank contents after transfer.
- Choosing stream using report timestamp
- Generalizing an inlet sample to all tank contents
Fields to preserve
- collection_time
- Selects source interval
- collection_location
- Distinguishes inlet from tank sample
- record_publication_time
- Keeps administrative timestamps separate
Test another case
Replace the instant grab with a composite collected from 10:50–11:10; record mixed intervals rather than a single stream.
No production stream compositions, process conditions, site identifiers or hazardous operating advice.

Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
