+
+## Schema highlights
+
+**`wax_deposition.csv`** — implements **NACE TM0274** wax-thermodynamic
+threshold gating:
+
+> wat = N(118, 8)  °F
+> deposition_rate = max(0, WAT − T_fluid) × U(0.01, 0.15)   mm/day
+
+This means **wax deposition is exactly zero when T_fluid ≥ WAT** (per Pedersen
+et al. 1991 thermodynamics — wax stays in solution above WAT) and scales
+positively with subcooling below WAT. The sample observes ~10% of rows in
+the deposition zone, matching the realistic fraction of pipeline operations
+that drop below WAT.
+
+**`asphaltene_precipitation.csv`** — implements **SPE 28994 (Hammami &
+Raines)** asphaltene-thermodynamic threshold gating:
+
+> aop = N(3500, 600)  psi
+> precipitation_rate = max(0, AOP − P_fluid) × U(0.0001, 0.005)
+
+Asphaltenes precipitate **only when P_fluid < AOP** (per asphaltene
+solubility thermodynamics — asphaltenes stay in solution above onset
+pressure). The sample observes ~18% of rows in the precipitation zone,
+matching the realistic fraction of pipeline operations that drop below AOP.
+
+**`thermal_profiles.csv`** — heat loss conditioned on delta-T per **ISO
+13703** subsea pipeline thermal design:
+
+> seabed_temp = N(40, 10)  °F
+> heat_loss = max(0, T_fluid − T_seabed) × U(1, 10)   BTU
+
+Heat loss only occurs when fluid is warmer than seabed (always true in this
+sample given fluid temp ~145°F vs seabed ~40°F).
+
+**`multiphase_flow.csv`** — 5-class flow regime classification per
+**Mandhane et al. (1974) / Beggs & Brill (1973)** flow-regime maps:
+slug / annular / bubble / stratified / churn. Sample distribution is
+near-uniform (~20% each) for ML-balanced classification training.
+
+**`integrity_risk_labels.csv`** — 3-class integrity grade derived from
+blockage probability:
+
+| Grade | Trigger |
+|---|---|
+| `LOW` | risk ≤ 0.45 |
+| `MEDIUM` | 0.45 < risk ≤ 0.75 |
+| `HIGH` | risk > 0.75 |
+
+---
+
+## Suggested use cases
+
+1. **Wax deposition rate regression** — predict
+   `deposition_rate_mm_day` from operating conditions
+   (temperature/pressure/flow_rate) and WAT. **Strong physics signal**:
+   threshold gating + delta-T correlation r ≈ 0.79.
+2. **Asphaltene precipitation regression** — predict
+   `precipitation_rate` from pressure conditions and AOP. **Strong
+   physics signal**: threshold gating + delta-P correlation r ≈ 0.75.
+3. **Flow regime classification** — multi-class (5-way) classifier on
+   `flow_regime` from gas/liquid fractions + slug frequency features.
+4. **Hydrate inhibition state classification** — 3-class (active/
+   partial/failed) classifier for inhibition effectiveness ML.
+5. **Pipeline integrity grading** — 3-class ordinal classifier on
+   `integrity_grade` (LOW/MEDIUM/HIGH) — useful as label-only
+   reference; see Honest Disclosure §3 for feature-engineering
+   caveats.
+6. **Chemical injection optimization** — regression on
+   `effectiveness_pct` from inhibitor type + dosage features for
+   chemical program tuning.
+7. **Heat loss prediction** — regression on `heat_loss_btu` from
+   fluid/seabed temperature + pipeline characteristics. Anchors to
+   ISO 13703 thermal design.
+8. **Multi-table relational ML** — entity-resolution and graph
+   neural-network learning across the 9 joinable tables via
+   `pipeline_id` + `condition_id`.

+## Loading
+
+```python
+from datasets import load_dataset
+ds = load_dataset("xpertsystems/oil015-sample", data_files="wax_deposition.csv")
+print(ds["train"][0])
+```
+
+Or with pandas:
+
+```python
+import pandas as pd
+pipelines  = pd.read_csv("hf://datasets/xpertsystems/oil015-sample/pipelines_master.csv")
+conditions = pd.read_csv("hf://datasets/xpertsystems/oil015-sample/operating_conditions.csv")
+wax        = pd.read_csv("hf://datasets/xpertsystems/oil015-sample/wax_deposition.csv")
+asp        = pd.read_csv("hf://datasets/xpertsystems/oil015-sample/asphaltene_precipitation.csv")
+
+# Wax deposition is keyed by condition_id (embedded in wax_id):
+wax["condition_id"] = wax["wax_id"].str.replace("WAX-", "", regex=False)
+wax_joined = wax.merge(conditions, on="condition_id")
+# Now you have WAT + T_fluid + P_fluid features ready for ML
+```
+

+
+## Reproducibility
+
+All generation is deterministic via the integer `seed` parameter (driving
+both `random.seed` and `np.random.seed`). A seed sweep across
+`[42, 7, 123, 2024, 99, 1]` confirms Grade A+ on every seed in this sample.
+
+---
+
+## Honest disclosure of sample-scale limitations
+
+This is a **sample** product for flow assurance ML research, not for live
+pipeline operations decisions. Several important notes:
+
+1. **Operating conditions are independent of pipeline characteristics.**
+   The generator samples pressure/temperature/flow_rate from fixed
+   Gaussians, *not* conditioned on pipeline diameter, water depth, design
+   pressure, or insulation type. This is a deliberate simplification for
+   ML-balanced training but is not realistic — real deepwater pipelines
+   run colder than onshore (better heat transfer to seabed), and design
+   pressure limits operating pressure. For physics-realistic conditioning
+   ML, treat operating conditions as features and pipeline characteristics
+   as separate features rather than expecting cross-table coupling.
+
+2. **Hydrate events have no thermodynamic gating.** Real hydrate
+   formation occurs **inside the hydrate envelope** (low T, high P region
+   per Sloan & Koh 2008). The generator samples `hydrate_risk_score`
+   from `N(0.35, 0.15)` independent of T/P, so hydrate risk is not
+   physically coupled to operating conditions. **This is a significant
+   simplification.** For hydrate ML that requires T-P-conditioned
+   risk, use a Sloan & Koh CSMHYD-style envelope calculation on top
+   of operating conditions, or wait for the full product v1.1 which
+   will introduce envelope-aware hydrate gating.
+
+3. **`integrity_risk_labels.csv` is feature-decoupled.** The blockage
+   probability is sampled from `N(0.25, 0.15)` independent of wax
+   deposition rate, asphaltene precipitation, hydrate risk, or other
+   upstream features. **Models trained to predict
+   `integrity_grade` from upstream features will not learn meaningful
+   patterns** because the label is not a function of the features.
+   This is a generator design choice (likely placeholder for future
+   coupling). For integrity-grade ML, build a derived label from
+   weighted combinations of `wax_thickness_mm`, `hydrate_risk_score`,
+   `precipitation_rate`, and `heat_loss_btu` rather than using the
+   sampled label directly. The integrity_risk_labels table is best
+   used as a **reference distribution** for production label
+   calibration, not as a supervised ML target.
+
+4. **Chemical injection effectiveness is uniform-sampled.** The
+   `effectiveness_pct` column from `U(40, 99)` is not tied to
+   inhibitor type, dosage, or operating conditions — so an "MEG @
+   100 ppm in a wax-deposition scenario" might show 95% effectiveness
+   in the sample, which is physically wrong (MEG is a hydrate
+   inhibitor, not a wax inhibitor). **Inhibitor-effectiveness ML on
+   this sample will learn marginals, not couplings.** For
+   physically-correct inhibitor-effectiveness ML, post-process the
+   data to align inhibitor type with deposition type, or wait for
+   the full product v1.1.
+
+5. **Wax/asphaltene rates are dimensionless multipliers**, not
+   physically calibrated. The wax `U(0.01, 0.15)` multiplier and
+   asphaltene `U(0.0001, 0.005)` multiplier produce rates in the
+   correct order of magnitude (mm/day for wax, dimensionless flux
+   for asphaltene) but are not calibrated to specific crude
+   compositions. For absolute-rate prediction, the labels need
+   recalibration against the user's crude assay; for relative
+   ranking ML (e.g., "which pipeline is most at risk"), the relative
+   ordering is preserved.
+
+6. **No time-series autocorrelation across hourly steps.** Each row
+   in `operating_conditions.csv` is sampled independently — there's
+   no Markov / AR / drift modeling across consecutive hours. **Time-
+   series ML that relies on temporal smoothness will not get
+   realistic signal from this data.** Treat the sample as a panel
+   of independent observations, not as time-series.
+
+7. **Pipeline length / diameter are uniformly distributed**, not
+   conditioned on pipeline type. Real LNG feed lines run 36"+ for
+   high-volume gas transport; real heavy-oil gathering lines are
+   typically 6-12". The sample uses U(4, 36) inches across all
+   types. For type-conditional ML, post-process the data with
+   industry-standard pipeline-sizing priors.
