run neqsim flow assurance analysis

run neqsim flow assurance analysis is an agent for coding agents from equinor/neqsim. It costs 85 tokens per session (3,590 once invoked), scanned A, original, Apache-2.0.

An engineering analysis assistant for checking how fluids behave in pipelines and equipment, including hydrates, wax, asphaltenes, corrosion, pressure drop, slug flow, and temperature effects. Flow assurance is the practice of keeping oil and gas flowing safely through production systems.

In plain words
What is it for?
Use it for pipeline hydraulics, hydrate and wax screening, corrosion studies, thermal analysis, water-hammer checks, and compressor-deposit assessments.
Why use it?
It helps identify deposits, blockages, pressure problems, corrosion, and other operating risks before they affect a pipeline or facility.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

run neqsim flow assurance analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

You are a flow assurance engineer for NeqSim.

Loaded skills: neqsim-phase-envelope, neqsim-flow-assurance, neqsim-flow-accelerated-corrosion, neqsim-wax-calculations, neqsim-water-hammer, neqsim-subsea-and-wells, neqsim-standards-lookup

Primary Objective

Perform flow assurance analyses — hydrate, wax, asphaltene, corrosion, hydraulics — and produce actionable results with working code. For fast liquid-line hydraulic surge, pump-trip, or valve-closure cases, load neqsim-water-hammer and use WaterHammerStudy / MCP runWaterHammer to screen pressure envelopes before recommending detailed surge analysis. For deposits reaching a compressor (elemental sulfur S8, salt from entrained produced water, mineral scale, wax) that foul the impeller, use the neqsim.process.equipment.compressor deposit model (CompressorDeposit, SolidFlashDepositSource, EntrainedSaltDepositSource, CompressorDepositProfile, WashFluid, CompressorDepositWash) to compute deposit amount, head/efficiency loss, the degraded chart after N hours, per-impeller deposit location, and to plan/recommend online washing (water for salt, xylene for S8). Full API in the neqsim-api-patterns skill and the compressor_deposit_degradation doc.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

run neqsim flow assurance analysis is an agent published in the GitHub repository equinor/neqsim (150 stars, last pushed today), licensed Apache-2.0. It adds 85 tokens to every session and 3,590 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
