FieldState Turns Brownfield Data Into Scalable Reservoir Surveillance

A reviewable workflow for fragmented production data, legacy documents and recurring QA/QC, from production baseline to reservoir evidence.

01
FFIELDSTATE
Your continuous production review

Recover value from production data you already have.

FieldState reviews every brownfield well on a recurring cadence and turns production signals into an evidence-backed action backlog: monitor, fix data, validate, or approve intervention.

See the asset-level backlog first, then drill into the well-level evidence.

Each candidate is ranked with screening-level economics before your team spends field or service dollars.

Your evidence

Concise at the top. Verifiable at the bottom.

Leadership gets the conclusion first. Engineers can drill into source data, formulas, segments and proxy assumptions before trusting the recommendation.

Top

Business conclusion

Recommended stance, value, urgency, owner and reason the prior read no longer applies.

Evidence

Source lineage

Production coverage, data-quality gates, selected intervals and excluded periods stay visible.

Math

Formulas and segments

DCA fits, economic inputs, segment choices, Basic NPV, IRR and confidence measures sit beside the result.

Assumptions

Proxy assumptions

Directional phase and rel-perm proxies are marked as proxies, not reservoir-model claims.

Drill-down

Calculation check

Technical pages let the operator trace the recommendation back to the underlying numbers.

03

Reliable Interpretation Starts With Reliable Data

Before any reservoir surveillance can be trusted, two interdependent workstreams have to move together: the data foundation that makes information usable, and the engineering interpretation built on top of it.

Data foundation and tools

Make structured and unstructured brownfield data usable without repeated manual collection, checking and re-formatting.

  • Scan, read and recognize legacy documents
  • Extract tables, facts, events and engineering signals
  • Normalize wells, rates, events and identifiers
  • Create shared analytical storage with traceable evidence

Engineering interpretation

Turn prepared and incoming data into a reviewed view of asset behavior that can be refreshed as conditions change.

  • One-time interpretation of existing data
  • Continuous interpretation as new data arrives
  • Operational event and intervention effects
  • Pressure, injection and connectivity signals

The bottleneck is not only fragmented data. It is the manual effort required to make that data usable every time the question changes.

02

Mature Assets Need Continuous Engineering Capacity, Not a One-Off Interpretation

A conventional service project can deliver a one-off interpretation. The harder problem is keeping interpretation accurate while assets keep changing, manual work accumulates and engineering capacity stays limited.

Point-in-time snapshot

A one-off report explains the data available today, then starts aging as soon as the asset changes.

  • Production baseline
  • Initial event chronology
  • Reservoir questions and data gaps

Manual change load

Even existing assets keep changing through rates, events, interventions, pressure updates and operating constraints, which creates repeated preparation and review work.

  • More trends to monitor
  • More assumptions to refresh
  • More evidence to review

Scaled engineering capacity

Continuous workflows help the same experts cover more fields while improving accuracy and reducing repeated manual rework.

  • Portfolio-level scaling
  • Reusable review logic
  • More current decisions

The value is not only interpretation quality. It is the ability to keep that quality current across more assets without scaling manual effort linearly.

Five Phases Turn Manual Data Work Into Repeatable Decision Gates

Each phase turns scattered inputs and manual checks into a concrete output and a decision gate. The timing reflects the current overlapping roadmap rather than a sequential waterfall.

Phase 1Production Intelligence
  • Rates, days-on, well metadata
  • Legacy documents
  • Extract, normalize, QA/QC
  • Build decline baseline
  • Trusted production baseline
  • Do-nothing forecast + economic limit
  • What the asset does today
  • How long it lives as-is
M1-M6
Phase 2Operational Intelligence
  • Workovers, uptime, choke settings
  • Operating events
  • Create event model
  • Build what-if and loss logic
  • Operational scenario workspace
  • Opportunity-loss view
  • Which levers matter
  • What to test first
M4-M10
Phase 3Reservoir Surveillance
  • Pressure, injection, well tests
  • Connectivity evidence
  • Run RTA and connectivity
  • Interpret pressure support
  • Pressure-aware reservoir behavior
  • Recovery impact view

  • Where losses and recovery remain

  • Well models, equipment limits
  • Surface constraints, historian path
  • Connect nodal/VLP logic
  • Add constraints and integrations
  • Constraint-aware workspace
  • Daily optimization view
  • Which actions are feasible
  • Which constraints block value

Data Needed by Phase

The discussion should confirm what data exists, what can be extracted quickly, and which later phases depend on sources that may not be ready on day one.

1. Production Intelligence

Minimum useful starting point.

  • Oil, water, gas rates
  • Days-on production
  • Basic well metadata
  • Legacy files for extraction
2. Operational Intelligence

Turns baseline into controllable scenarios.

  • Choke settings
  • Uptime and downtime
  • Workover / intervention history
  • Event chronology
3. Reservoir Surveillance

Moves from production behavior to reservoir behavior.

  • Pressure data
  • Injection history
  • Well tests
  • Connectivity evidence
4. Integrated Optimization

Connects engineering constraints to operations.

  • Well models
  • Equipment limits
  • Surface constraints
  • SCADA / historian path
5. Agentic Engineering

Requires validated workflows before AI can assist safely.

  • Engineering rules
  • Approval constraints
  • Workflow history
  • Review evidence packs
05

AI Removes Manual Work Around the Engineering Process

Document and table extraction

Legacy reports, scans and spreadsheets are converted into structured, source-linked facts.

Normalization and QA/QC

Wells, dates, units, events and gaps are checked before engineers spend time on interpretation.

Evidence packs for review

Assumptions, confidence and source references are prepared for SME review.

Workflow automation

Repeatable phase tasks and review gates become traceable workflows instead of ad hoc manual work.

Continuous refresh

New incoming data updates the surveillance state without rebuilding the whole interpretation from scratch.

AI is used around the engineering workflow: preparation, checking, evidence and refresh. Engineers still approve interpretation and decisions.

08

The First Discussion Should Confirm Where Manual Data Work Blocks Surveillance

We do not need to price the full program in the first meeting. We should confirm the asset scope, available data, manual bottlenecks and the first useful decision gate.

1

Asset scope

Fields, wells, systems and the surveillance priority you want to address first.

2

Available data

Production exports, legacy documents, event history, pressure, injection and well-test evidence.

3

Manual bottlenecks

Where engineers spend time collecting, checking, reconciling or explaining data today.

4

First decision gate

The first phase output that would be useful enough to plan in detail with your team.
