Trueb Depth Imaging

  • True Depth Through Global Delta Determination
  • Traditionally the condition that a correct velocity model has been derived is that the migrated gathers are flat.
  • This can be accomplished by picking the correct interval velocities and epsilon fields.
  • However, to guarantee that the depth predicted bythe PSDM matches that of the refectors in the earth true depths are assessed from the well formation tops.
  • DIAMOND has a new way to determine a global delta field using the mismatch between the reflectors depths from the well logs and the seismic. in conjunction with the velocity and epsilon it produces an image that is accurate in depth.

Marine Time Processing

Advanced Signal Processing for Data Conditioning, Interactive Data Analysis and QC

  • Time processing at GTI includes topics such as advanced signal (time) processing for data conditioning, interactive data analysis, time imaging, broadband processing and integrity validation (QC). In addition, tools are available for qualitative and quantitative gather conditioning and AVO analysis for both time and depth gathers.

Marine Depth Processing

Advanced 3D and 2D Data Processing for Subsalt Imaging

Our Depth Imaging and Interpretation experience drives GTI advanced modeling, velocity analysis, anisotropic parameter estimation and imaging. Coupled with our time processing and. Furthermore, our global data library has provided a foundation of worldwide imaging challenges including, but not limited to orthorhombic anisotropy, gas chimneys and subsalt imaging.

Land Seismic Data Processing

GTI is a leader in advanced seismic processing for challenging onshore environments. We have the tools, knowledge, and global experience to take on land imaging projects including fracture detection in tight sands, shale plays, and carbonate reservoirs throughout the world. We partner with E&P operators to help them better understand the geology of unconventional reservoirs throughout the world, including shale and tight gas plays, enabling them to maximize exploration and production of their reservoirs.

Key services we offer in the land environment include:

  • Data Conditioning
  • Velocity Model Building
  • Azimuthal Anisotropy (AZIM) and Offset Vector Tiling (OVT) PreSTM
  • PreSTM
  • PreSDM
  • AVO Inversion
  • Multicomponent imaging
