Schema highlights

wells_master.csv — one row per well, the relational spine. Key columns: well_id, well_type (12-class: vertical_conventional, directional, horizontal_shale, extended_reach, deepwater_offshore, hpht, geothermal, managed_pressure, underbalanced, salt_section, multilateral, slim_hole), basin (11-class: Permian, Eagle Ford, Bakken, Marcellus-Utica, Gulf of Mexico, North Sea, Middle East, Brazil Pre-Salt, Canada Oil Sands, Geothermal Basins, Other), total_depth_ft, well_trajectory_type, mud_system (water/oil/synthetic/cesium formate).

MSE follows the Teale (1965) formulation with bit-size-aware area:

MSE = (WOB / A_bit) + (120·π·RPM·T_bit) / (A_bit · ROP)

where A_bit varies by hole section (17.5" surface, 12.25" intermediate, 8.5" production, 6.125" lateral), and T_bit is downhole bit torque estimated as 25-45% of surface torque depending on trajectory and depth — a critical detail for accurate MSE in long-reach and horizontal wells.

Formation strength profiles (mse_log.formation_strength_psi) follow basin-specific UCS bands with stochastic formation transitions every 500-2000 ft: Permian 8-22 kpsi, Marcellus-Utica 11-25 kpsi, Brazil Pre-Salt 15-35 kpsi, Geothermal Basins 18-40 kpsi.

Rheology coupling — PV and YP share an underlying rheology level correlated with mud weight, producing the field-realistic PV-YP correlation of ~0.70-0.85 (Bourgoyne et al. 1986).

ECD margin (ecd_ppg - mud_weight_ppg) is calibrated to maintain the ~0.45 ppg overpressure circulation envelope per IADC guidance, with depth-scaled annular friction and ROP-dependent cuttings loading.

Bit wear uses the IADC dull grading taxonomy (8 codes spanning worn-teeth, broken-teeth, lost-teeth, ring-out, balled-up patterns), with dull grade escalation driven by cumulative footage and average formation strength per bit run.

Suggested use cases

1. ROP optimization regression — predict ROP from WOB, RPM, torque, mud weight, formation UCS using the 109,870-row time-series spine.
2. MSE efficiency classification — train models on bit_efficiency to identify low-energy-efficient drilling sections.
3. Dysfunction detection — multi-class classifier on dysfunction_class (11-class: stick-slip, lateral vibration, stuck pipe, washout, twist-off, mud loss/gain, bit balling, pack-off, whirl, axial bounce) from vibration
   • mechanical telemetry.
4. Stuck pipe early warning — binary classification with the stuck_pipe_precursor events as positive labels, ROP/WOB/torque time- series as features.
5. Bit dull grade prediction — regress IADC dull grade from cumulative footage and formation strength exposure per bit run.
6. Drilling efficiency grading — multi-class classification on the drilling_efficiency_grade (A+/A/B/C/D) target from per-well aggregated features.
7. Time-series forecasting — predict next-stand ROP / MSE / vibration from the prior stand's drilling parameters (sequence models, transformers).
8. Multi-table relational ML — entity-resolution and graph-based learning across the 9 joinable tables via well_id.

Loading

from datasets import load_dataset
ds = load_dataset("xpertsystems/oil007-sample", data_files="drilling_timeseries.csv")
print(ds["train"][0])

Or with pandas:

import pandas as pd
wells = pd.read_csv("hf://datasets/xpertsystems/oil007-sample/wells_master.csv")
ts    = pd.read_csv("hf://datasets/xpertsystems/oil007-sample/drilling_timeseries.csv")
mse   = pd.read_csv("hf://datasets/xpertsystems/oil007-sample/mse_log.csv")
events = pd.read_csv("hf://datasets/xpertsystems/oil007-sample/drilling_events.csv")
joined = ts.merge(wells, on="well_id")

Reproducibility

All generation is deterministic via the integer seed parameter through per-well SeedSequence([master_seed, well_idx]) derivation, guaranteeing schema-stable joins across runs and seed-by-seed reproducibility.

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 drilling- parameter research, not for live drilling operations. A few notes:

1. Time-series is decimated 4× in the sample. Full product runs at the generator's native cadence (~42 samples per stand at 1 Hz / 85 ft/hr). The sample uses --decimate 4 to keep file sizes <15 MB while preserving stand-resolution detail. For high-frequency vibration ML, use the full product (12,000 wells, undecimated).

2. ECD margin runs slightly below the 0.45 ppg target (observed mean ~0.37 ppg) at sample scale, well within the ±0.15 ppg tolerance. This reflects the stochastic depth-scaled annular friction modeling; full- product scale converges closer to 0.45 ppg as the basin/well-type mix averages out.

3. Max depth capped at 12,000 ft in the sample (vs 22,000 ft in the full product). This caps the Pre-Salt and HPHT extreme-depth physics slightly under-represented. Wells assigned to those types still get their depth/mud-weight modifiers applied within the 12 kft envelope.

4. Inter-stand jitter uses per-stand-seeded RNG for intra-stand sample variation. This produces stand-coherent telemetry (good for ML) but means within-stand noise is correlated stand-to-stand at fixed offsets. For pure-noise modeling, filter out the per-stand structure first.

5. Per-well stuck pipe / washout / dysfunction event rates are per-stand Bernoulli probabilities, so total event counts per well are Poisson-distributed (~6 events/well average at sample scale). Production runs (longer wells, more stands) will see proportionally more events per well.
