Sounds familiar?

"The EXCEL® trap"

Your proxy model is in a spreadsheet. You know it is an approximation. Your client is making a multimillion Dollar decision on it.

"The enterprise price wall"

Other solutions cost several thousand Dollar a year. Your company will not approve it. Your competitor already has it.

"The Linux installation is a nightmare"

You downloaded OPM Flow. You spent three days on a Linux server configuring HPC. You never ran your first model.

"Which pre or post processor software should I use?"

You are using several solutions and none of them is really useful.

RUNSPEC answers all four.

Replace EXCEL®

Full OPM Flow simulation. Not material balance. Not a type curve. A defensible dynamic reservoir model.

From €49 a month

The same physics engine used in academic research and other commercial projects. Professional results at consultant pricing.

No Linux required

Browser-based. Sign up. Describe your reservoir. Run a simulation. Cloud compute included in your subscription.

The entire workflow is captured.

All in a single place, from data loading, preparing to results viewing → in no time.

SPECTREAI · TRAILER

FOUR WAYS TO BUILD

One platform. Four paths.

01

SpectreAI

Natural-language prompt → validated OPM Flow deck (reproducible in Runspec) → production dashboards → decision-ready PDF briefing. From scope to result in one session.

  • Full briefing PDF export
  • Assumption tracking and documentation
  • Production Dashboard
  • Decision Support
02

RUNSPEC

Form-based deck builder with guided section-by-section input. Grid · PVT · SCAL · Wells · Schedule — validated at every step.

  • Cartesian + corner-point grid import
  • PVT correlations or manual tables
  • SCAL correlations (Corey or LET)
  • Full keyword audit trail
03

Keyword Editor

Full keyword control with AI support.

  • E100 → OPM migrator built-in
  • Version-tracked edits
  • Full keyword documentation
  • Error debugging with AI support and solution recommendations
04

Monte Carlo

Latin Hypercube Monte Carlo for uncertainty and sensitivity screening.

  • Fully probabilistic
  • Real-time plotting and visualisation
  • RSM response surface approach
  • Tornado charts · P10/P50/P90
SPECTREAI · DECISION SUPPORT LOOP

Four steps. One session.

>

Create a simple anticline, crest at 3000m, 8° dip, N-S trending, 40×40×8 grid, Metric, 1× producer, OWC at 3200m and producing bhp controlled with 50 bar and 2× injectors injecting at initial pressure, for a 25 years forecast.

1
Describe the scope

Tell SpectreAI the decision you're supporting — in plain English. No keyword syntax, no deck structure.

2
Agree on assumptions

SpectreAI proposes every model assumption. Each value is visible, editable and confirmable. You stay in control. You get it documented in MD format.

3
Run — dashboards in minutes

One click. OPM Flow runs on managed cloud. FOPT, FWCT, GOR, pressure, 3D saturation maps — all in the browser.

4
Decision briefing

SpectreAI delivers a structured engineering briefing — model rationale, confirmed assumptions, forecast, recommendation. Ready to present and ready to defend.

5
Reproducible in Runspec (no black box)

AI-generated models are reproducible in Runspec — no black box, fully transparent. Every keyword, assumption and grid visible and editable.

SpectreAI — describe scope SpectreAI — assumptions SpectreAI — results dashboard SpectreAI — decision briefing Runspec — reproducible 3D model

Not a simulation file — a decision document.

MULTI-ENERGY

One platform. Four energy sectors.

OIL & GAS

Oil & Gas

Black oil, gas condensate, and compositional models. Proxy studies, scenario planning, P10/P50/P90.

CCS / CO₂ STORAGE

CCS / CO₂ Storage

Saline aquifer injection, plume migration, capacity estimation. EU-mandate ready.

GEOTHERMAL

Low-enthalpy Geothermal & EGS

Doublet modelling, aquifer thermal energy storage, Enhanced Geothermal Systems. Not steam-dominated.

H₂ STORAGE

H₂ Underground Storage

Hydrogen injection in depleted gas fields and saline aquifers. First cloud-native tool for H₂.

Built for the right problems. Honest about the rest.

RUNSPEC IS BUILT FOR
  • Proxy models and rapid sensitivity studies
  • Scenario planning for investment decisions (P10/P50/P90)
  • Independent consultants without enterprise licenses
  • CCS, geothermal and H₂ teams without simulation access
  • Engineers who need a defensible result by Friday
NOT YET BUILT FOR
  • 50-million cell full-field geological models
  • Super complex SCHEDULE features and well event sequences
  • Certified ECLIPSE output for regulatory submission
  • Steam-dominated geothermal

If you need a defensible answer by Friday, RUNSPEC is your tool. If you need full-field history matching with 200 wells — you still need other solutions. We will tell you that upfront.

DATA SECURITY

Your data stays in Europe.

Infrastructure

Hetzner Online GmbH, Falkenstein & Nürnberg, Germany. EU jurisdiction. No US cloud providers for simulation data.

Simulation engine

OPM Flow (GPL v3) — open-source, auditable, no vendor lock-in. Source: github.com/OPM

AI processing
