neqsim-anp-open-data

neqsim-anp-open-data is a skill for Claude Code, Codex from equinor/neqsim-community-skills. It costs 104 tokens per session (3,643 once invoked), scanned A, original, Apache-2.0.

A guide to Brazil's ANP open data, the public information published by the National Agency of Petroleum, Natural Gas and Biofuels. It explains where to find block, field, well, production, seismic, investment, and government-payment data and how to check units, dates, and coordinate systems.

In plain words
What is it for?
It is for researching Brazilian oil and gas blocks, fields, wells, production, technical data, exploration plans, and government payments, especially in the Santos and Campos basins.
Why use it?
It helps prevent mistakes caused by unfamiliar Portuguese dataset names, changing file formats, wrong units, or incorrect map coordinates. It also provides a way to use offline reference copies when live access is unavailable.

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

neqsim-anp-open-data 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.

The scan reads SKILL.md. This mod also ships 9 executable files (src/anp_open_data/__init__.py, src/anp_open_data/bathymetry.py, src/anp_open_data/overview.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ANP Open Data

Advisory skill. It is the Brazilian counterpart of neqsim-norwegian-continental-shelf-data and says what to read, how to trust it and how to hand it on.

When to Use

  • A task needs Brazilian block, field production or well facts for a Santos, Campos or other Brazilian block.
  • A host field such as a pre-salt FPSO must be characterised from public data.
  • A Sodir-like open-data basis is needed for a Brazilian evaluation.
  • Nearby FPSOs, fields, wells or gas export lines must be located on a map, or tie-in hosts ranked for a Brazilian discovery.

Inputs

  • The downloaded ANP file and its documentation (header names, separator, decimal mark, encoding, units).
  • A header mapping from the names you need to the names in the file.
  • The block or field name and the year range of interest.

Outputs

  • Typed rows with explicit unit conversions (oil and gas volumes, daily rates).
  • A CRS check for block coordinates and a distance to the host.
  • Source, dataset name and download date for references/SOURCES.md.
  • Approximate installation positions with spread and water depth, latest and peak daily rates per installation, distances to pipelines, and a ranked tie-in host table.

What to look for

The ANP open-data page (checked 2026-10-09, gov.br/anp, "Dados abertos"; also mirrored on dados.gov.br) lists these datasets by name. Names are in Portuguese:

  • Bid rounds and blocks: "Rodadas de Licitações de Petróleo e Gás Natural", "Fase de Exploração", "Fase de Desenvolvimento e Produção", "Blocos com Fase Exploratória Encerrada", "Dados Georreferenciados das Bacias Sedimentares Brasileiras".
  • Production: "Produção de Petróleo e Gás Natural por Poço", "Produção de petróleo e gás natural por estado e localização". Well-level files are read by neqsim-anp-well-production-history; units differ by family (bbl/dia and Mm³/dia = thousand m³/d in the by-well rate files; m³ and Mm³ per month in the volume files).
  • Wells and technical data: "Resultado de poço", "Dados de E&P", "Acervo de Dados Técnicos", "Amostras de Rochas e Fluidos".
  • Planning and money: "Previsão de Atividades e Investimentos Exploratórios", "Participações Governamentais".

Changes

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.
