neqsim-production-optimization SKILL.md skillA
neqsim-production-optimization from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add equinor/neqsim/neqsim-production-optimization@git:20261023.92beb0dPins git:20261023.92beb0d in mdr.lock. Pin the fingerprint instead.

Production optimization, bottleneck analysis, decline curves and history matching (Arps, Duong), material-balance surveillance (OGIP/OOIP, drive indices, aquifer) and IOR/EOR screening with NeqSim. USE WHEN: optimizing rates, finding facility bottlenecks, forecasting profiles, fitting decline curves, estimating reserves, allocating gas lift, comparing production scenarios, or generating Eclipse/OPM VFPPROD lift-curve tables from a NeqSim pipe model.
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 Production Optimization Skill
Reference for production forecasting, optimization, bottleneck analysis, and
improved recovery using NeqSim's field development and process simulation tools.

## Production Profile Modeling
### Decline Curve Types
| Model | Formula | Use Case |
|-------|---------|----------|
| Exponential | $q(t) = q_i e^{-Dt}$ | Gas wells, constant decline |
| Hyperbolic | $q(t) = q_i (1 + bDt)^{-1/b}$ | Oil wells, b = 0.3-0.8 |
| Harmonic | $q(t) = q_i / (1 + Dt)$ | Hyperbolic with b = 1 |
| Plateau + exponential | Build-up → plateau → decline | Constrained by facility |
### Production Profile Generation
```java
ProductionProfile profile = new ProductionProfile();
// Method 1: Arps decline
profile.setDeclineModel(ProductionProfile.DeclineModel.EXPONENTIAL);
profile.setPeakRate(25000.0); // boe/d
profile.setDeclineRate(0.15); // 15% per year (Di)
profile.setPlateauDuration(3); // years at peak
profile.setProjectLife(25); // total years
double[] rates = profile.generateProfile();
// Method 2: Hyperbolic with b-factor
profile.setDeclineModel(ProductionProfile.DeclineModel.HYPERBOLIC);
profile.setHyperbolicB(0.5);

How to install
mdr add equinor/neqsim/neqsim-production-optimization@sha256:04d5a1381c7ff26dThe line at the top of this page pins the label git:20261023.92beb0d, 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.
