neqsim-production-chemistry SKILL.md skillA
neqsim-production-chemistry from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Production-chemistry patterns for NeqSim. USE WHEN: selecting or dosing scale/corrosion/hydrate/wax/asphaltene inhibitors, H2S or oxygen scavengers, biocide, demulsifier, antifoam, pH adjuster or acid; checking chemical-chemical or chemical-fluid COMPATIBILITY; computing minimum dose, residual SI, inhibited corrosion rate or scavenger breakthrough; placing an injection point; or chemical root-cause of a deposit, emulsion, pH excursion or H2S breakthrough.
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
# Production Chemistry with NeqSim `neqsim.process.chemistry` is an open, standards-traceable production-chemistry stack: chemical inventory, compatibility rules, per-threat dose-response models, a flowsheet-visible injection point, and an explainable root-cause analyser. Every model exposes `getStandardsApplied()` and `toMap()` / `toJson()` so results drop straight into `results.json`. ## When to Use This Skill - Which chemical, which chemistry family, and **what dose** for a given threat - **Compatibility** of a chemical cocktail with itself, with the produced water, and with the material - Minimum inhibitor concentration (MIC), residual SI after treatment, inhibited corrosion rate - H2S scavenger demand, capacity and breakthrough time - Hydrate inhibitor (MEG/MeOH) injection rate for a target subcooling; KHI induction time - Demulsifier dose vs oil-in-water spec, dosing lag, monthly compliance - How a pH adjuster / scavenger shifts the brine chemistry and the scaling tendency - Chemical incident root cause (deposit, emulsion, corrosion, pH excursion, H2S breakthrough) - Uncertainty (P10/P50/P90) on any of the above ## What This Skill Is NOT …

How to install
mdr add equinor/neqsim/neqsim-production-chemistry@sha256:81998f9bbe7093e5The line at the top of this page pins the label git:20261028.56febaa, 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.
