AsterWell Operations: Mathematical Model, Units & Reproducible Benchmarks
Role & Domain Intent: Industrial operations modelling (Drilling time, fuel and carbon; not dispatch logistics or well control.)
Equations, Variables & Dimensional Rules
Drilling duration, fuel and carbon estimation using interval, penetration-rate and nonproductive-time assumptions.
Drilling Time T_drill = Interval (m) / ROP (m/h); Total Duration T_total = T_drill / (1 − NPT_pct/100); Fuel (L) = T_total × Fuel_Rate (L/h); Emissions (tCO2e) = Fuel (L) × EF (kgCO2e/L) / 1,000; Cost = Fixed_Cost + (T_total / 24) × Daily_Rate
Declared Units: Interval in metres (m); rate of penetration (ROP) in m/h; nonproductive time (NPT) in %; duration in hours (h) and days (d); fuel in litres (L); carbon emissions in metric tonnes CO2e (tCO2e); cost in assumed USD.
Step-by-Step Numerical Verification
Case 1 (800 m interval, ROP = 10 m/h, NPT = 10%, Daily Rate = 24,000 USD/d, Fixed Cost = 50,000 USD, Fuel Rate = 180 L/h, EF = 2.68 kgCO2e/L): Net drilling time = 80.0 h; with 10% NPT, T_total = 80 / 0.9 = 88.89 h (3.704 days). Total Fuel = 88.889 × 180 = 16,000 L; Emissions = 16,000 × 2.68 / 1,000 = 42.88 tCO2e; Estimated Cost = 50,000 + 3.7037 × 24,000 = 138,888.89 USD.
| Case | Interval (m) | ROP (m/h) | NPT (%) | Total Time (h) | Fuel (L) | Emissions (tCO2e) | Est. Cost (USD) |
|---|---|---|---|---|---|---|---|
| Case 1 (Baseline) | 800 | 10.0 | 10% | 88.89 | 16,000 | 42.88 | 138,888.89 |
| Case 2 (Hard Formation) | 1,200 | 8.0 | 15% | 176.47 | 31,765 | 85.13 | 226,470.59 |
| Case 3 (High Efficiency) | 800 | 12.5 | 5% | 67.37 | 12,126 | 32.50 | 117,368.42 |

Scope: Integer-cent allocation and reconciliation on fictional meeting records.
Boundary & Limitation: Not a certified accounting system, legal compliance or live organizational records.
Distributable_Pool (cents) = Net_Result_Cents + Carry_Forward_Cents − Prior_Legal_Reserve_Cents; Reconciliation_Delta (cents) = Distributable_Pool − (Dividends_Cents + New_Legal_Reserve_Cents + Other_Reserve_Cents + New_Carry_Forward_Cents)
Units & Conventions: All monetary balances in exact integer cents (100 cents = 1.00 currency unit); zero floating-point rounding drift.
Worked Verification Example: Case 1 (Ordinary Meeting Review, Carry Forward = 500,000 cents, Proposed Dividends = 400,000 cents): Integer-cent reconciliation checks whether proposed reserve transfers, dividends, and ending carry-forward balance exactly to the cent and flags any governance mandate or quorum metadata gaps in the fictional record.
| Case ID | Meeting Kind | Carry Forward (cents) | Dividends (cents) | Arithmetic Precision | Verification Scope |
|---|---|---|---|---|---|
| Case 1 | Ordinary | 500,000 | 400,000 | Exact Integer Cents | Fictional Governance Record |
| Case 2 | Extraordinary | 1,250,000 | 800,000 | Exact Integer Cents | Reserve Allocation Check |
| Case 3 | Annual Review | 320,000 | 350,000 | Exact Integer Cents | Deficit / Imbalance Flagged |
