Transforming 2D Seismic Data into 3D Volumes

A Padetech Perspective

Seismic data is the foundation of subsurface understanding. For decades, geoscientists have relied on 2D seismic lines to interpret underground structures. While 2D data offers valuable insights, it often falls short in capturing the full complexity of geological formations. That’s where Padetech comes in.

As a consultancy recognized for its seismic imaging expertise, Padetech specializes in converting legacy 2D seismic datasets into high-resolution 3D volumes, delivering clarity, confidence, and a competitive advantage to operators across the energy and environmental sectors.

Why Padetech Leads in Seismic Transformation

Padetech’s team combines broad technical knowledge with deep domain experience. Our experts are highly regarded in seismic imaging, having worked with small independents, mid-sized operators, and Fortune 100 globalcompanies. We understand the nuances of every basin, every dataset, and every decision point.

By transforming 2D seismic data into 3D volumes, Padetech helps clients:

• Improve fault and horizon mapping

• Detect subtle geological features like channels and fractures

• Enhance reservoir characterization and volumetric estimates

• Reduce drilling risk and optimize development strategies

  
  

Understanding the Limitations of 2D Seismic

2D seismic lines represent vertical slices of the Earth’s subsurface. While useful, they lack the spatial continuity needed to interpret complex structures fully. Common limitations include:

• Incomplete spatial coverage

• Difficulty resolving faults and folds

• Limited visibility of subtle features

• Reduced accuracy in reservoir modeling

Despite these constraints, 2D surveys remain popular due to their lower cost and faster acquisition. Padetech helps clients unlock their full value.

How Padetech Converts 2D Data into 3D Volumes

We use a combination of advanced geophysical techniques and proprietary workflows to generate reliable 3D seismic volumes from 2D inputs. Our methods include:

1. Interpolation Between 2D Lines

When 2D lines are acquired in a grid, Padetech applies spatial interpolation techniques—such as kriging, inverse distance weighting, and spline modeling—to estimate seismic properties between lines and build a continuous 3D volume.

2. Seismic Reprocessing and Migration

Using original seismic records, we apply velocity models and 3D migration algorithms to reposition reflections in their actual subsurface locations. This enhances image fidelity and reduces artifacts.

3. Model-Based Reconstruction

For sparse or irregular datasets, Padetech integrates well data, geological maps, and seismic attributes to build geologically consistent 3D models. These models honor both the seismic data and known subsurface conditions.
