Schema highlights

bits_master.csv — the bit catalog spine, one row per bit. 4 bit types (PDC, Roller Cone, Hybrid, Diamond Impregnated), 3 manufacturer classes (Premium, Mid-Tier, Budget), bit size 6-18 inches, blade count 4-8, cutter count from N(45, 12).

drilling_runs.csv — 5 runs per bit on average. Each run carries formation context (5-class: Permian shale, carbonate, abrasive sandstone, deepwater turbidite, geothermal hard rock), depth interval, bit life in hours, and the average ROP for that run. The avg_rop_fph column is the seed for downstream drilling_parameters ROP samples (each per-stand ROP sample is N(run_avg_rop, 8)).

drilling_parameters.csv — 5-15 WOB/RPM/torque/ROP/MSE-efficiency samples per run. WOB N(38 klbs, 8), RPM N(145, 25), Torque N(18,500 ft-lb, 3,500), MSE efficiency N(0.88, 0.04).

bit_wear_logs.csv — IADC dull grade taxonomy (1-1-WT worn-teeth, 2-2-BT broken-teeth, 3-3-ER edge-rounded, 4-4-BH balled-up-with-heat), plus cutter wear % (N(46, 12)) and bearing wear % (N(35, 15)).

vibration_measurements.csv — three-axis g-force measurements matching modern downhole accelerometer ranges: axial N(1.8 g, 0.6), torsional N(2.1 g, 0.7), lateral N(1.5 g, 0.5), whirl index N(0.18, 0.04).

hydraulic_performance.csv — flow rate N(650 gpm, 120), pressure drop N(2,200 psi, 300), HSI (hydraulic horsepower per square inch of bit area) N(1.6 hp/in², 0.25), hydraulic efficiency N(0.91, 0.03).

thermal_profiles.csv — bottomhole temperature N(245°F, 30), cutter temperature N(380°F, 45), thermal cycles U(20, 400).

dysfunction_events.csv — sparse table, only ~35% of runs have a dysfunction event (per the 0.35 trigger probability). 5-class dysfunction taxonomy: stick-slip, bit whirl, bounce, balling, thermal overload. Severity 0-1, downtime 5-300 minutes.

drillbit_labels.csv — three ML targets:

• rop_efficiency_grade (A/B/C/D) computed from avg_rop_fph / 72 thresholds (≥1.1=A, ≥0.95=B, ≥0.8=C, else D)
• optimal_bit_flag (binary, 1 when efficiency > 1.0)
• failure_risk_score (continuous, 0-1)

Suggested use cases

1. Bit-type selection ML — multi-class classifier on bit_type from formation + depth + manufacturer-class features, trained against ROP-grade target.
2. ROP-grade classification — train classifiers on rop_efficiency_grade (A/B/C/D) using drilling parameters, hydraulics, vibration, and bit spec features.
3. Bit wear regression — predict cutter_wear_pct and bearing_wear_pct from run depth, formation, drilling parameters, and thermal exposure.
4. Dysfunction detection — binary classifier on whether a run experiences a dysfunction event (join dysfunction_events to runs; ~35% positive rate). Then a 5-class secondary classifier on which dysfunction type given an event.
5. MSE optimization — regress mse_efficiency from WOB, RPM, torque, ROP using the 142,002-row drilling-parameters spine (5-15 samples per run for distribution-aware training).
6. Hydraulic efficiency prediction — predict hydraulic_efficiency from flow rate, pressure drop, HSI, and bit size.
7. Thermal overload risk — binary classifier predicting thermal-overload dysfunction from BH temperature, cutter temperature, and thermal cycles.
8. Multi-table relational ML — entity-resolution and graph-based learning across the 9 joinable tables via bit_id and run_id.

Reproducibility

All generation is deterministic via the integer seed parameter (driving 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 calibrated for ML prototyping and bit- performance research, not for live bit-selection decisions. The generator is a direct-sampling design (independent Gaussian draws around industry-anchored target means) — fast to validate and easy to extend, but with several limitations users should know about:

1. No cross-feature physics coupling. Each table is sampled independently of the others — WOB and torque are not correlated, vibration and dysfunction events are uncoupled, and thermal exposure does not drive wear progression. ML models trained on this sample will learn marginal distributions but will not learn realistic cross-feature relationships. The full OIL-010 product (v1.1 roadmap) will introduce physics coupling via shared latent factors (UCS-driven ROP, WOB-driven torque, thermal-driven cutter wear, vibration-driven dysfunction).

2. Formation and dysfunction are uniformly sampled, not conditioned. In real drilling data, geothermal hard rock has very different dysfunction profiles (thermal overload dominant) than Permian shale (stick-slip dominant). The sample uses uniform 5-class draws for both; treat the joint distribution as ML-balanced rather than field-realistic.

3. Three CSVs listed in the generator docstring are not generated in this version: lithology_transitions.csv, directional_performance.csv, and economics_metrics.csv. These will ship in OIL-010 v1.1. Current product is 9 CSVs.

4. Long-tail cutter-count outliers. Cutter counts are drawn from N(45, 12), so a small fraction of bits (~0.1%) have unrealistically low cutter counts (<5). PDC bits in practice have 30-80 cutters; filter cutter_count >= 20 if you need clean PDC training data.

5. MSE efficiency is sampled, not computed. The mse_efficiency column is a direct Gaussian draw N(0.88, 0.04), not derived from the Pessier MSE formulation (MSE = WOB/A + 120·π·N·T / (A·ROP)). For physically-consistent MSE labels, use OIL-007 (Drilling Parameters), which implements the full Teale/Pessier MSE physics with bit-size-aware area.

6. All non-bit-master tables use uniform/Gaussian random IDs. The well_id field in drilling_runs.csv samples from a 50,000-well synthetic pool independently per run, so the same well will not typically appear in multiple runs in the sample. For ML that requires well-level grouping, the full product introduces realistic well clustering.
