Deepwater Fields

Clear vision when you’re "in deep".

Global oil markets are rebounding. Commodity prices are rising.  If you’re ready to “go deep” again, how about making AspenTech Subsurface Science & Engineering (SSE) your technology partner?

In deepwater acreage, the ability to image complicated salt features and associated overturned sediment rafts and overthrusts is invaluable. The comprehensive velocity modeling and imaging capabilities of AspenTech SSE provide high-quality anisotropic velocity models and volumes, suitable for volumetric interpretation, classification, prospecting, QSI activities, pore pressure prediction and modeling.

In addition, our modeling, formation evaluation and well planning solutions are well suited for operations in high-pressure and high-temperature regimes, and are particularly effective for deep water, subsalt objectives.



Imagine lowering a camera into the earth's subsurface and recording a continuous animation in all directions and angles. EarthStudy 360™ makes this level of detail possible. The full-azimuth angle domain depth imaging and analysis system uses the complete recorded wavefield to provide a highly accurate and detailed description of the subsurface. Unlike traditional approaches that use limited surface azimuth sectors of imaged seismic data, this process recovers 360 degrees of full-azimuth data, in situ, in depth, and over all reflection angles. Rays can be identified as upward/downward, inward/outward, and filtered accordingly to achieve the desired image - this is particularly useful in salt regimes. Customized diffraction energy images and specular images can be generated for prospecting in the presence of salt and subsalt. As a result, observation, measurement and interpretation of subtle structure, salt flanks, fractures and elastic properties are more visible, repeatable and quantifiable. Equally important, project turnaround times are dramatically improved so that geoscientists and reservoir engineers can effectively use outputs when developing the field.

This patented imaging technology is complemented by Reverse Time Migration (RTM), highly suitable for subsalt imaging objectives in the presence of salt.  RTM can also be run in forward modeling mode to validate subsurface models.



You want more than commonplace “me too” functionality for your teams; you want to equip them with tools which will deliver competitive advantages. AspenTech SSE offers a distinct collection of powerful, easily accessible interpretation tools.  Eliminating the need to move data or leave the interpretation platform reduces your non-productive time and lowers the learning curve.

Machine Learning Techniques for Seismic Facies Classification, Multi-attribute Volume Classification and Lithofacies Prediction

  • Quantitative Seismic Interpretation (QSI), including a rich library of AVO and seismic inversion methods, can be carried out without ever having to leave the interpretation canvases. These methods greatly enhance prospecting, ranking and well planning activities.
  • Advanced Attributes, RGB/HSV Visualization and Voxel-based Interpretation, including a rich library of physical and geometric attributes, multi-volume blending techniques and advanced formation sculpting and voxel detection methods, ideal for tracking depositional features like turbidites.
  • Advanced Structural Interpretation methods, including computer-assisted and Automatic Fault Extraction to rapidly assess complex fault systems, including those exposed by proprietary diffraction imaging methods, Fault Likelihood and Coherence Cube® attributes.
  • Chronostratigraphic Interpretation for solving difficult correlation problems in the presence of faults and complex stratigraphic sequences.  Interpretation can be automated and validated at unprecedented speed.

Operating on the Epos™ database, interpreters have access to a true multi-user environment, allowing teams of geoscientists and engineers to simultaneously work across an entire deepwater basin, with customized data security and access. Does the deepwater basin cut across various Coordinate Reference Systems? Not a problem. AspenTech SSE manages data presentation to the user across CRS.


Understanding pore pressure is very important in deep prospects. Pore pressure predictions can be made based on seismic velocities calibrated to well and field test information.  Seismic velocities can be better defined with a 3D model that includes the major structural and stratigraphic elements. Additionally, the well tie can be facilitated through the use of a desktop global tomography algorithm which does not require prestack gathers or cluster computing and honors constraints for both geological and geophysical systems.  Anisotropy (VTI, TTI, Tilted Orthorhombic) can be modeled and updated with model-based and grid-based solutions.

Subsalt imaging can be very tricky. The illumination analysis tools integrated into our interpretation environment provide key diagnostics to evaluate the dependency of the seismic acquisition and velocity model on the seismic image.

Geomechanical risks associated with deep water plays need to be understood. Borehole methods incorporating well bore stress and well bore stability can be deployed. New hybrid geomechanical grids can be generated for subsequent analysis and geomechanical simulation.

Creating a drill plan for high pressure and high temperatures is supported in our drilling application. For example, Sysdrill™ Fluid Temperature Modeling enables accurate prediction of ECD and ESD downhole mud density and rheology under HPHT conditions.
