Full wave modeling

We use Tesseral to complete 2.5D full wave modeling, which enables the construction of realistic 3D models that include

• the ability to define a true elastic model
• the ability to account for thing-layering effects
• tilted transverse isotropy of the media
• fractured media.

Tesseral 2.5D provides full wave finite-difference elastic modeling for a multi-parameter medium model including anisotropy, fracturing, and absorbing (Q) properties. The forward modeling is performed in true 3D and the media within the model is simplified to 2.5D. This provides virtually the same results as the full 3D wave equation modeling and can be used for the creation of 3D-3C data sets for survey planning.

Ray tracing and illumination studies

Use the NORSAR-3D modeling package to generate target illumination maps consisting of hit maps, amplitude density maps, and simulated migration amplitude maps and verify that a candidate acquisition survey will illuminate a reservoir target adequately.

Full-wave acquisition design

MESA is the industry standard for 2D, 3D, 4D, and full-wave acquisition design. Plan, model, and track surveys in simple or complex acquisition scenarios; lay out source, receiver, and bin patterns, and “shoot” the survey; and analyze acquisition attributes such as fold, offset, and azimuth distribution. The programs can also be used to analyze migration halo, spatial sampling, line spacing, offsets and a host of other geophysical calculations that are critical for properly imaging geophysical objectives, as well modeling energy with full 3D ray-tracing and creating synthetic traces for experimentation.
