Oil & gas field economics, NPV, IRR, cash flow, and fiscal regime modeling with NeqSim. USE WHEN: calculating project economics (NPV, IRR, payback), evaluating tax regimes (Norwegian NCS, UK, generic), building cost estimates (CAPEX/OPEX), or running Monte Carlo sensitivity analysis on economic outcomes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NeqSim Field Economics Skill
Reference for petroleum project economics — cost estimation, cash flow modeling,
tax regimes, NPV/IRR calculations, breakeven analysis, and uncertainty.

### CAPEX Components (Typical Offshore NCS)
| Category | Typical Range | NeqSim Class |
|----------|--------------|--------------|
| Wells (drilling + completion) | 200-800 MNOK/well | `WellCostEstimator`, `WellMechanicalDesign` |
| SURF (subsea, umbilicals, risers, flowlines) | 500-5000 MNOK | `SURFCostEstimator` |
| Topsides / Processing | 2000-15000 MNOK | `FacilityBuilder` + `MechanicalDesign` |
| Subsea equipment (trees, manifolds) | 100-500 MNOK/well | `SubseaProductionSystem` |
| Pipeline / Export | 50-300 MNOK/km | `PipelineMechanicalDesign` |

How to install
mdr add equinor/neqsim/neqsim-field-economics@sha256:6b7841d1dc5c0755The line at the top of this page pins the label git:20261025.a31b8bb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
