Frame the decision
Define the uncertainty, expected signal, decision threshold, and monitoring cadence.
Time-lapse subsurface intelligence
See the reservoir. Understand the change.
Explore documented 4D seismic projects, compare the acquisition choices behind repeatability, and connect observed change to monitoring decisions.

Three direct routes
Start with the engineering question.
The Hub is organized around three practical tasks: locate an analogous field project, compare the technical choices behind performance, and understand what the evidence can support.

Find a relevant field case.
Browse projects by monitoring objective, reservoir setting, sensor system, region, evidence scope, and source grade.
Compare technical choices.
Inspect NRMS, repeat interval, bin size, water depth, signal driver, and provenance without collapsing unlike metrics into a synthetic score.
Interpret the evidence.
Read decision-focused analyses that separate source records, editorial synthesis, limitations, and community review.
Latest field notes
Evidence distilled for engineering reuse.
Recent analyses focus on the monitoring problem, the evidence produced, and the operational judgment that followed.
Gullfaks 4D seismic: 10 years of experience
How repeated streamer surveys moved 4D seismic from an experiment into routine reservoir-management decisions at Gullfaks.

Cases with explicit evidence boundaries.
Each record connects the monitoring uncertainty, acquisition response, observed evidence, operational outcome, and limits on transferability.
Middle East Carbonate OBN
Detecting subtle pressure depletion in stiff carbonates using high-repeatability OBN.
View in library →Gullfaks Main Field
The pioneer of 4D. Identified undrained compartments leading to over $1B in added value since 1996.
Read case →Valhall LoFS
First Life-of-Field Seismic (PRM). Over 20 surveys acquired, driving virtually every infill well decision.
View in library →The 4D decision chain
Monitoring value is created across the whole loop.
A strong program connects acquisition repeatability to interpretable change, then connects that change to a reservoir or storage decision.
Design for repeatability
Control geometry, positioning, equipment behavior, environmental variation, and timing.
Separate signal from noise
Process the difference while tracking repeatability metrics and interpretation uncertainty.
Act on the evidence
Translate observed change into well, injection, depletion, compaction, or storage action.
