DecisionSpace Geophysics software continues that legacy, featuring all our seismic expertise, with a special focus on making workflows faster, easier, and more scientifically robust than ever.

More and more oil and gas discoveries occur in highly complex, challenging settings. Solving today’s subsurface puzzles means leveraging geophysical data and collaborating across domains quickly and seamlessly. With Landmark’s multi-user workspace and innovative seismic interpretation tools, your team can contribute to a common sealed 3D structural framework while they interpret, then create presentation-quality maps – in minutes.

Accelerate traditional workflows.

Traditional horizon and fault interpretation can be tedious and time-consuming. DecisionSpace® Geophysics​ software's ezTracker™software  technology does automated or semi-automated waveform tracking for you. Interactive map, section and cube displays accelerate fault picking and QC. And proven high-performance 3D Probe technology enables rapid animation and validation of ideas.

Leverage innovative new tools.

Use the Vertical Images tool to display published cross sections and other images along any line of section with seismic data. Use the Geoshaper™ freehand drawing tool to interpret where there is no data, fill in lithology, and map out plays. With GIS integration, geo-reference images and view ESRI shape files in seismic context. Integrate prestack seismic into reservoir characterization workflows in the same workspace.

Build structural frameworks dynamically.

Building a structural framework typically requires manually digitizing fault polygons and other time consuming tasks. Landmark's advanced topology engine and Dynamic Frameworks to Fill® workflow lets each team member contribute directly to a dynamic structural framework with properly sealed faults, unconformities, and horizons, as they interpret. As new data is added, updates cascade through the entire model.

Revolutionize mapping.

Geophysicists spend as much as 80% of their time making maps. DecisionSpace® Geophysics software revolutionizes mapping workflows. It slashes interpretation cycle time by an order of magnitude while improving both accuracy and consistency. With the Dynamic Frameworks to Fill technology, structural and property mapping is only a button-click away from interpretation.

Integrate beyond seismic.

Built on the OpenWorks® database, DecisionSpace software easily integrates data types and expands workflows across traditional domains. Interact with classic Landmark tools, enhancing your workflows with the power of GeoProbe® software, for example. Applications share seismic data in memory, interacting dynamically via undocked windows, cursor tracking, and drag and drop.​

The DecisionSpace® Seismic Interpretation component provides the core seismic interpretation workflows for mapping subsurface geology. The application provides the geophysical interpreter with full 2D/3D seismic interpretation workflows from basic visualization in multiple views to advanced multi-attribute analysis.  The DecisionSpace Seismic Interpretation software also includes robust horizon and fault interpretation for trap definition workflows along with amplitude extraction for fill prediction.

In addition to fundamental geophysical interpretation tools, the software’s tight integration in the DecisionSpace Geoscience suite offers highly innovative subsurface workflows.

Basin scale analysis to better understand play fairways and basin trends
Built on the OpenWorks® project data management database, DecisionSpace Seismic Interpretation excels for interpreting in large scale complex 2D and 3D seismic projects with time and depth seismic of different vintages, which allows the interpreter the ability to perform seismic interpretation at the continental scale.
 
Accelerates interpretation and reduces rework
DecisionSpace software enables cross-domain collaboration to optimize all phases of the seismic interpretation workflow, from basin analysis through 4D earth modeling to appraisal well planning and drilling.  As you interpret, updates to interpretations are dynamically incorporated into the structural framework, enabling asset teams to quickly optimize, present, and defend technical analyses in complex environments.
 

The DecisionSpace® Seismic Analysis component is designed to provide the seismic interpreter with advanced geophysical workflows that leverage Landmark’s DecisionSpace platform benefits of subsurface visualization and dynamic project updating while extending unique geophysical approaches for quantifying and qualifying subsurface challenges. As seismic acquisition increases in cost and orientation complexity, the application helps ensure that asset teams can extract the maximum value from their seismic data during interpretive project phases.  Some of the high-graded workflows that make up the application’s toolkit include: advanced well-tie, prestack seismic visualization and quality control, and seismic horizon autopicking. Whether leveraged for stratigraphic or structural geologic challenges, the DecisionSpace Seismic Analysis component ultimately provides the interpreter with a better understanding of reservoir makeup, fluid presence, and optimal well planning.

Validates Geologic Assumptions with Seismic Data
The DecisionSpace Seismic Analysis component provides insight in understanding which seismic reflectors match specific geologic events within the well data, which allows for precise trap definition so that more accurate decisions can be made for well placement, reserve estimation, and even facilities setting.
 
Quantifies Best Prospects and Reservoir Potential
Analysis and visualization capabilities allow the interpreter to understand the seismic response to fluid and lithology changes that may be seen in the subsurface.   This can be essential in determining the actual reservoir makeup and help defend justification of the best potential reservoirs for prospect ranking, acreage capture, and well placement.
 
Interpretation Confidence
Through visual access and quality control of prestack data, the interpreter can better ascertain the quality characteristics of their seismic data, which, ultimately, increases their interpretation confidence.
 

From complex structure to subtle stratigraphy, seismic attributes remain one of the most dependable tools for direct hydrocarbon identification as well as providing an invaluable visual reference to the interpreter performing complex fault and horizon interpretations.  DecisionSpace® Seismic Attribute software provides the functionality to calculate seismic attributes as well as perform additional post-processing signal enhancements on any attribute or seismic volume.

Signal enhancement and volume calculations improve the seismic without processing cost or delays
The DecisionSpace Seismic Attribute integrated interpretation environment provides fundamental seismic processing tools for 2D, 3D, and volume processes, which gives the interpreter the ability to filter, enhance, or test different signature parameters directly from the interpretation workspace without having to wait for a reprocessing exercise.
 
DecisionSpace Geoscience Software Scenario Testing Enables “What If ” Prestack and PostStack™ Application Comparisons
The ability to interactively view the seismic data effects on the fly within a common viewing window allows for more precise understanding of data quality and interpretation readiness.
 
Multi-View 1D/2D/3D Provides Precise Geologic Perspective in context of horizons and faults
The interpreter has flexible yet precise control to view seismic data from multiple perspectives to gain the best understanding of the geologic influences on their horizon and fault interpretation. All windows can be interpreted within and dynamically shared between views, making activities like standard attribute based, fault interpretation picking, efficient and accurate.
 
Comprehensive Library of Proven PostStack Attribute Calculations
A thorough list of fundamental seismic attributes includes common amplitude, phase, frequency, shaded relief, dip, azimuth, Structure Cube™ application for discontinuity, and curvature attributes.

Time to Depth Conversion provides flexibility to work in any domain
The interpreter is provided the flexibility to work in time, depth, or both domains giving them the ability to craft a “best practice” workflow relative to their available data, interpretation challenge and delivery requirements.

The DecisionSpace® Velocity Modeling application provides a solution for building velocity models that incorporates raw, edited and interpreted data, as well as existing velocity model information, to build geologically sound velocity models between the well control.  Landmark’s innovative use of a multi-resolution model incorporates well and seismic information so that interpreters can easily build geologically sound models even in structurally complex geologic regimes. By giving the interpreter the ability to incorporate seismic, well data, interpreted horizons, faulted frameworks, and multi-Z salt-body objects, as well as other attributes like density and anisotropy, the software can be applied to a multitude of workflows, such as seismic imaging, depth conversion, seismic inversion, AVO analysis, fracture detection, pore-pressure prediction, and reservoir modeling.

More Value with an Integrated 3D Velocity Solution
Built in the unified DecisionSpace software suite, velocity models are displayed and evaluated along with seismic, well, and structural interpretations, which leads to increased confidence in the velocity model.
 
Velocity Models that Assimilate Well and Seismic on the Fly

Empowers True Interpretive Processing Workflows for Accurate Model Collaboration
Unique “hybrid” velocity model design provides for a memory-efficient model. This model can be shared between the processor and interpreter, enabling optimized seismic imaging activities like prestack reverse-time migrations.
 
Data Integrity in Complex Geology
Geologically accurate structures are built using Dynamic Frameworks to Fill® conformance technology. Velocity Modeling integrates the accurate geologic structures with all the relevant time and depth subsurface data from vertical/deviated/horizontal wells and seismic data to build a geologically optimal velocity model. This approach leads to a geologically sound model in complex geology.
 
Flexible Model Design can be Accessed Across Deepwater and Unconventional Workflows

Prestack interpretation remains one of the most reliable indicators of reservoir property identification especially in complex geologic environments where seismic data is essential to validating subsurface understanding.  DecisionSpace® Prestack Calibration and Analysis software offers a comprehensive prestack interpretation component that is completely integrated in the DecisionSpace Geoscience suite and provides the seismic interpreter with dynamic access to large prestack volumes for processing, analysis and correlation with other reservoir data types. The software also empowers workflows for calibrating seismic data to geology for the extraction of essential information to better generate quality prospects, seek bypassed reserves, or to enhance reservoir characterization workflows. The location of cross-plotted attributes classified for fluids or fracture response can be projected onto map, section, and cube view displays. The application supports seismic modeling activities to help interpreters understand seismic behavior, including normal incidence and offset modeling, P-P and P-S wavelet estimation, and synthetic scaling. To help the geoscientist validate their interpretation with observed seismic responses, log modeling tools are included and contain fluid and porosity substitution, saturation and mixed phase scenario modeling. The software also includes tools for extraction, synthetic generation, and manipulation.

 

Comprehensive Prestack Data Quality and Anomaly Analysis
The application provides a powerful set of features that can allow the interpreter to ensure the precision of the seismic data quality while also understanding the interpretive influence of acquisition and anisotropic conditions. Analysis capabilities allow for the ranking of seismic anomalies cause and effect, so that amplitude anomalies and their reservoir relevance are better understood. Also, the application can consume VSPs and other related project data.
 
Hydrocarbon Indicators Better Understood Though Lithology and Fluid Prediction
Prestack seismic remains one of the most reliable tools for hydrocarbon identification. DecisionSpace Prestack Calibration and Analysis software provides unique workflows for understanding the amplitude and azimuthal dependent effects on the seismic data so interpreters can more confidently discern between actual geologic conditions or seismic acquisition artifacts. Beyond that, advanced AVO and lithology features provide direct understanding of hydrocarbon presence.
 
Seismic Scenario Testing That Enables “What If” Prestack and Poststack Comparisons
The ability to interactively view the seismic data effects on the stacking or re-stacking of seismic surveys on the fly within the same viewing window allows for more precise understanding of data quality and interpretation readiness.
