Report day summary

24.0 h observed, including 5.0 h confirmed NPT. 3.4 h drilling ILT against the 35 ft/h benchmark.

Calculated from validated source events · 100.0% report-day coverage

Benchmark-adjusted efficiency

Shown only when the full day is observed, all time is classified, and the selected drilling benchmark covers every productive minute. This scenario metric is not a universal field-efficiency score.

Not available

86.8% of productive time benchmark eligible

Confirmed NPT

Only time explicitly classified NPT in the report; multiplied by the rig-rate assumption for cost.

5.0 h

Drilling ILT

Eligible drilling duration less footage / selected benchmark. Trip ILT remains unknown.

Mantle · SYNTHETIC DEMO — illustrative events, not actual field records. Classifications come from the report. Flat hole depth alone does not prove downtime. ILT, financial exposure and CO₂ are scenario estimates, not audited losses or measured emissions. Human review required.

Source warnings (4)
  • This is a synthetic demo, not a source-verified industry report.
  • Drilling ROP benchmark and rig day rate are editable scenario assumptions.
  • ILT cannot be evaluated for every productive interval. Trip speed requires separate bit/string movement; hole depth is insufficient.
  • Benchmark-adjusted efficiency is unavailable because the drilling benchmark covers only 86.8% of productive time. Unobserved or unbenchmarked time is not assumed to meet target.

SYNTHETIC DEMO — illustrative events, not actual field records. Financial exposure, ILT, fuel and CO₂ are scenario estimates, not audited losses or measured emissions. Flat hole depth alone does not prove downtime. Hole measured depth is not drill-bit position. Human review is required; this report provides no equipment diagnosis or field instruction.

Scenario assumptions and calculation basis

Rig day rate: $120,000/day. Drilling benchmark: 35 ft/h. Incremental excess fuel: 60 gal/h. Carbon factor: 10.18 kg CO₂/gal.

Efficiency = (productive time − eligible drilling ILT) / classified time; unknown classification is excluded. NPT comes from report classifications. Drilling ILT compares supported productive drilling intervals with the selected benchmark. Time exposure uses (NPT + eligible ILT) × rig day rate / 24 hours. Fuel and carbon require an explicit incremental fuel assumption. Trip ILT is unavailable without bit/string movement observations. Benchmarks depend on the well section and formation.
