Custody Measurement Layer

Agree the measurement.
Reconcile the transfer.

Run an automated custody transfer reconciliation between refinery and pipeline operator based on verified flow measurement at the transfer point. Anchored flow data reconciles custody transfer volumes between the two parties on data both trust, so small measurement discrepancies no longer accumulate into disputed amounts.

The Foundation

The Execution Mechanics

Turn accumulating measurement discrepancies into an automatic reconciliation on data both parties trust.

01.

Verified Flow Measurement

External Data Oracles anchor flow measurement at the custody transfer point, so the volume that determines billing rests on data both parties can verify.

02.

Two-Party Reconciliation

The refinery and pipeline operator reconcile against the same anchored measurement, so a transfer volume is agreed rather than contested.

03.

Discrepancy Detection

The Audit Logs module flags any measurement discrepancy at the transfer point, stopping small differences from accumulating into large disputed amounts.

04.

Automatic Settlement

Escrow and Conditional Settlement settles the reconciled volume between parties, removing the manual measurement dispute process.

05.

Transfer History

Every transfer measurement and reconciliation is retained, giving both parties a verifiable history of custody volumes over time.

06.

Dispute Elimination

Because both parties settle on shared measurement data, disputes over refinery-to-pipeline custody volumes are eliminated at source.

The Custody Measurement Lifecycle

Follow a single refinery-to-pipeline transfer from flow measurement through reconciliation to automatic settlement.

Smart Contract Anatomy

Cerulea decomposes custody measurement reconciliation into modular contracts. Each layer anchors flow, matches parties, checks discrepancy, and settles automatically.

Applicability Across the Spectrum

Automated custody measurement reconciliation is a horizontal capability. Here is how different actors at the transfer point put the shared ledger to work.

Refinery Operators

Settle product transfers on measurement both parties trust, ending the accumulating discrepancies and disputes that came from unmatched custody meters.

Network & Execution Architecture

Whether you are bridging custody metering systems or reading directly from the transfer-point flow computer, Cerulea routes both into one reconciliation ledger.

Track A: Custody Metering Bridging

For operators on legacy custody metering systems. Measurement data is translated into signed on-chain transfer records through the API gateway.

Technical Methodology

The legacy timeline reflects custody settlement integration benchmarks. Wiring custody metering, building custom reconciliation logic, and shipping automatic settlement for an average transfer point takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your measurement and settlement rules into pre-audited WebAssembly binaries and provisions the reconciliation ledger instantly.
