Bayesian AI for stratigraphy

Probabilistic AI for the Earth's subsurface

Weeks to hours

Manual correlation of multi-well datasets can take weeks. StratoBayes delivers ranked correlations in hours, so geologists spend their time on interpretation rather than alignment.

σ

Uncertainty you can act on

Every result carries quantified probabilities and alternative scenarios, so you know how much weight each correlated horizon can bear.

Results you can defend

Output is reproducible and auditable, built for regulatory evidence and investment cases and grounded in a peer-reviewed method.

How it works

Bayesian machine learning, in plain sight

StratoBayes learns from your data, weighs competing hypotheses and states how confident it is in each one.

01

Load your data

Import depth-referenced records from two or more boreholes, wells or outcrop sections, such as well logs, geochemistry and lithology.

02

The engine weighs the possibilities

The Bayesian engine evaluates thousands of candidate alignments, allowing sedimentation rates to vary between sites and updating its probabilities as the evidence adds up.

03

Get ranked correlations

You receive the most probable correlations, ranked, with uncertainty estimates for every matched horizon, ready to inspect, adjust and export.

Use cases

Wherever wells need aligning

Carbon storage

Correlate storage and monitoring wells with quantified uncertainty for site characterisation and the evidence regulators expect.

Geothermal

Trace target horizons between wells to estimate reservoir continuity before committing to the next borehole.

Mining and critical minerals

Align drillhole geochemistry across a deposit to follow ore-bearing horizons and plan follow-up drilling.

Oil and gas

Automate multi-well log correlation to keep reservoir models current through appraisal and development.

Infrastructure

Build a probabilistic picture of the ground between site-investigation boreholes before tunnelling or foundation design.

Research

Correlate cores and outcrop sections on to a shared timescale using the method published in Geochronology.

From Durham research to industry use

StratoBayes is a Durham University spin-out, completed in June 2026, building on research licensed from the University.

The method is peer-reviewed in Geochronology 7(4), 545-570, 2025. The international patent application is published as WO 2025/196391 A1, with the UK patent expected to grant in September 2026.

What we're building next

Today the engine correlates boreholes with quantified uncertainty. Next, we are building a foundation model for the subsurface, with the same Bayesian engine at its core, so machines can learn the statistical structure of the ground the way weather models have learned the atmosphere.
