Independent subsurface consultancy
Decisions rest on the model. We make the model worth it.
PetroPeers builds, rebuilds and independently assures the static geological models behind appraisal, development and storage decisions — and tells you plainly where the uncertainty actually sits.

What we do
Subsurface work that survives the next review.
A geological model is an interpretation of the reservoir and associated property distribution. We build models that are internally consistent, honest about their assumptions, and ready for the reservoir engineer, the auditor and the partner who disagrees with you.
Subsurface assurance & peer review
Independent QA/QC of models built in-house, by a previous consultant or by the operator. Structured, decision-based assurance with a documented QC trail — not a list of opinions.
- Model QC
- Peer assist
- Operator influence
Uncertainty & scenario modelling
Workflow-driven sensitivity and uncertainty analysis. Screen the parameters that actually move volumes, then deliver low, mid and high realisations that can be carried through to simulation and economics.
- Sensitivity
- P90 / P50 / P10
- Workflows
Prospect evaluation, risking & ranking
A consistent chance-of-success framework applied across a portfolio, so that prospects, leads and near-field opportunities can be compared on the same terms and ranked for a drilling campaign.
- Volumetrics
- Risking
- Portfolio ranking
Field development planning
Coordination of the G&G component of FDPs and development projects: scope, deliverables and resourcing, development and infill well locations, sidetrack decision trees, and the G&G work programme that gets a discovery to sanction.
- FDP support
- Well locations
- G&G programmes
Seismic interpretation & fracture characterisation
2D and 3D interpretation, depth conversion, fault seal analysis, and image-log-calibrated fracture networks built from ant-tracked volumes for fractured reservoirs.
- 2D / 3D
- Depth conversion
- Ant-tracking
- DFN
Resource estimation & reporting
Volumetric distributions, classification, annual resource reporting and audit support.
Due diligence & data rooms
Fast, structured technical evaluation for farm-ins, acquisitions and divestments.
Well operations support
Well proposals, evaluation programmes, wellsite supervision and pre/post-drill review.
Mentoring & capability building
Peer assists, structured coaching and modelling training for in-house teams.
Capability
From the seismic volume to the simulation deck.
Four things we are asked for most often, and what each one actually involves.
01 — Static modelling
Models built to be simulated, not admired.
A static model earns its keep when the reservoir engineer can run it and the result still honours the geology. We build the structural framework, zonation, facies and property distributions with the dynamic end-use in mind from day one — including the upscaling decisions and the history-match iterations that follow.
- Fault framework, horizon modelling and zone definition tied to the seismic interpretation
- Facies modelling grounded in a stated depositional model, not just a variogram
- Saturation functions QC'd against log Sw checked well by well
- Upscaling reviewed so simulation runtimes stay workable without losing the flow units
02 — Assurance
An independent read on somebody else's model.
Non-operated partners, boards and lenders often need to know whether a model can be relied on before money moves. We review the work that has been done, document what we checked and why, and give a clear position — including the case where the answer is "this is sound".
- Decision-based assurance against a structured static-model QA/QC framework
- Correlation, zonation and data-quality review before any property is questioned
- QC plots that make the argument visible: modelled saturation height vs log derived saturation, well sections, property distributions
- Findings written for the manager, not just for the geologist who built it
03 — Uncertainty & resources
Numbers you can defend.
A single deterministic case is a hypothesis, not a resource estimate. We build the uncertainty workflow around the parameters that genuinely move in-place and recoverable volumes, then carry a coherent low–mid–high set through to simulation, reporting and economics.
- Sensitivity screening to separate the parameters that matter from the ones that don't
- Stochastic realisations and volumetric distributions built from documented workflows
- Resource classification and reporting that stands up to audit
- Low, mid and high profiles handed over in a form the economics team can use directly
04 — Complex reservoirs
Fractured, faulted and carbonate systems.
Where flow is controlled by fractures or by a compartmentalised fault framework, the conventional property model is only half the story. We build fracture networks from ant-tracked seismic volumes calibrated to borehole image interpretation, then tune fracture intensity until the model reproduces the permeability seen at the wells.
- Ant-tracking and structural attribute work to map the fracture-prone volume
- Image-log interpretation used as the calibration basis, not as decoration
- Fracture intensity distributions tuned to interpreted fracture permeability at well locations
- Fault seal analysis and compartmentalisation testing for faulted developments
Where the work lands
Same discipline, different question.
Producing fields, exploration portfolios, gas storage, and CO2 sequestration all ask a version of the same question: how confident are we in the reservoir property distribution, and what would change the answer.
Development & production
Near-field appraisal, infill and development well locations, history-match support, reservoir characterisation, and the subsurface coordination that keeps an operator and a joint venture pointed at the same picture.
Exploration & appraisal
Prospect generation and evaluation, risking and ranking, volumetrics, appraisal well proposals, and pre- and post-drill resource and risk review for a drilling campaign.
Gas storage & CO2 sequestration
Storage-site characterisation, capacity and containment, stochastic models built for plume simulation, and the uncertainty analysis needed to establish whether a site is suitable in the first place.
Transactions
Data room evaluation, farm-in screening and technical due diligence under deal timelines.
Independent expert advice
Technical opinion for legal counsel, boards and investors on reservoir and modelling matters.
Non-operated ventures
Reviewing and influencing operator work, and preparing the JV's own independent position.
Government & research programmes
Multi-disciplinary subsurface studies delivered to milestone, scope and budget.
How we work
Scope it properly, then be straight about the result.
Most subsurface projects fail on scope and handover rather than on technique. We agree the deliverables and the decision they feed before any grid is built.
Scope & data audit
Define the decision the model has to support, then audit what the data can actually carry. Deliverables, timeline and the assumptions we are prepared to defend are written down at the start.
Build
Framework, zonation, facies and properties, built in tNavigator, Petrel, RMS or your own environment so the model stays maintainable by your team after handover.
Test the uncertainty
Sensitivity screening, stochastic realisations and volumetric distributions — and a plain statement of where the result is fragile.
Hand over & support
Documented workflows, QC plots and a walkthrough with the people who inherit it, plus continued support through simulation, history matching and partner review.

About PetroPeers
A peer, not a supplier.
PetroPeers is a specialist subsurface consultancy working with operators, non-operated joint ventures, storage developers, investors and legal counsel. The name is the brief: senior geoscience delivered as a peer to your team — close enough to be useful, independent enough to disagree.
Senior delivery, start to finish
The person who scopes the work is the person who builds the model and presents the result. No handing the build down a level once the contract is signed.
Operator-side experience
Three decades inside operators and joint ventures across exploration, development, production and storage — so recommendations account for what a project can actually absorb.
Built for the next reviewer
Workflows, assumptions and QC are documented as the work proceeds, so the model can be audited, updated and defended long after handover.
A straight answer
Independence is only worth paying for if it comes with candour — including when the finding is inconvenient, or when the existing model turns out to be fine.
Software
Work is delivered in the client's own environment wherever possible, so the model stays maintainable in-house.

A model review that changes nothing is still worth having. One that changes the drilling programme is worth a great deal more.
Independent review work has moved opportunities from the relinquishment conversation to the top of a campaign — and, just as often, confirmed that an existing model was sound and the team could proceed. Both outcomes are the deliverable.
