DecisionSpace Geosciences (DSG) is an integrated subsurface interpretation platform developed by Halliburton Landmark. It is used by geoscientists and engineers to interpret seismic data, well logs, geological structures, and reservoir properties for oil and gas exploration and development. The software helps teams understand the subsurface structure and reservoir characteristics to make better drilling and field development decisions.

 

 

DecisionSpace Geosciences is designed to support:

• Seismic interpretation
• Geological modeling
• Well correlation
• Reservoir characterization
• Prospect evaluation
• Field development planning

It integrates multiple types of subsurface data into a single interpretation environment.

Core Modules and Capabilities

1. Seismic Interpretation

This module allows geophysicists to interpret 2D and 3D seismic data.

Key capabilities include:

• Horizon picking
• Fault interpretation
• Seismic attribute analysis
• Seismic amplitude analysis
• Structural mapping

It helps identify:

• Reservoir structures
• Fault systems
• Traps for hydrocarbons

2. Well Log Interpretation

DecisionSpace can import and analyze well log data such as:

• Gamma Ray
• Resistivity
• Density
• Neutron
• Sonic logs

Functions include:

• Well correlation
• Stratigraphic interpretation
• Log visualization
• Petrophysical property analysis

3. Geological Modeling

The platform allows geologists to build 3D geological models of reservoirs.

These models include:

• Structural framework
• Stratigraphic layers
• Facies distribution
• Reservoir properties

This helps visualize the geometry of the reservoir in three dimensions.

4. Seismic Attributes and Advanced Analysis

DecisionSpace provides tools to compute and analyze seismic attributes, such as:

• Amplitude
• Coherence
• Curvature
• Spectral decomposition

These attributes help identify:

• Channels
• Fractures
• Thin beds
• Reservoir boundaries

5. Prospect Evaluation

Geoscientists can evaluate potential drilling targets by analyzing:

• Structural traps
• Reservoir quality
• Seal integrity
• Hydrocarbon indicators

This helps determine the risk and potential value of exploration prospects.

6. Data Integration

One of the key strengths of DecisionSpace is integrating different data types, including:

• Seismic data
• Well logs
• Core data
• Geological maps
• Production data

This integration helps build a complete subsurface interpretation.

Visualization Tools

DecisionSpace offers advanced visualization features such as:

• 3D seismic visualization
• 3D reservoir models
• Interactive cross‑sections
• Well path visualization

These tools help geoscientists understand complex geological structures.
