neqsim-tight-reservoir-test-design SKILL.md skillA

neqsim-tight-reservoir-test-design from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add equinor/neqsim/neqsim-tight-reservoir-test-design@git:20261026.b9133bb

Pins git:20261026.b9133bb in mdr.lock. Pin the fingerprint instead.

Screening workflow for opening a tight (chalk, tight carbonate or sandstone) reservoir through an existing host: stimulated-horizontal-well rate and EUR with NeqSim PVT, Arps extrapolation bias, production-test duration and sampling, flowback chemistry and compatibility, value of information of the test and stage-gate criteria. USE WHEN: designing a production test, drainage strategy or stage-gate pipeline for a tight reservoir tied to an existing facility (chalk analogues).

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

# Tight-reservoir test design and stage-gate screening

Reference implementation: `task_solve/2026-10-09_ofc_rc7_shetland_chalk_further_development/step2_analysis/scripts` (`chalkmodel.py`, `econ.py`, `04_fluid_compat.py`, `05_economics_mc.py`). Copy the pattern, not the numbers.

## 1. Order of work

1. **Public evidence first** (Sodir resource reports, field news, EAGE/SPE abstracts), saved to `references/literature`. Sodir FactMaps wellbore layers (204, 205) answer "which wells found hydrocarbons in formation X"; page with `resultOffset` and filter client side (the WAF rejects `LIKE '%..%'` filters).
2. **Fluid from NeqSim**: reservoir T, p, Psat (`bubblePointPressureFlash`), compressibility from density at p and p+10 bar, viscosity, Bo and GOR from a 3-stage flash, TVP of the stock-tank oil. These feed the well model.

How to install

The exact contents, by fingerprint
mdr add equinor/neqsim/neqsim-tight-reservoir-test-design@sha256:8ca8a395e1f505b0

The line at the top of this page pins the label git:20261026.b9133bb, 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.
