Seismic Processor on Delfi

Enables geophysicists to easily and intuitively manage seismic data and projects, build tailored geophysical workflows, quickly analyze, visualize and quality control both signal processing and depth-imaging results with the ability to interactively generate velocity solutions.

Includes Omega Processing Suite.

Access Omega software advanced technology bundles

Time-processing bundle

With the time-processing bundle, geophysicists can access a wide array of geophysical algorithms to enable signal processing, geometry and statics, velocity analysis and picking, de-multiple algorithms, multicomponent processing, and time migrations. The time-processing bundle enables pre-stack and post-stack 2D and 3D migrations, including Kirchhoff time migration (CPU and/or graphics processing unit [GPU]) and finite-difference algorithms.

Depth-processing bundle

The depth-processing bundle enhances the time-processing bundle by adding algorithms that enable common image-point model building and pre-stack and post-stack depth migrations (isotropic and anisotropic velocity models), including Kirchhoff depth migration (CPU and/or GPU).

Advanced signal-processing bundle

The advanced signal-processing bundle includes technologies in four areas: near-surface characterization, post-imaging data conditioning and enhancement, broadband processing (de-ghosting, noise attenuation, and bandwidth extension), and simultaneous source separation.

Advanced de-multiple bundle

The advanced de-multiple bundle addresses the free surface, shallow water layer, and internal multiples, to create multiple-free data, which is critical to the success of subsequent imaging and reservoir-characterization workflows. The techniques are velocity independent, work in 3D, and typically can be applied to most acquisition geometries without the need to perform interpolation or regularization.

Advanced interpolation bundle

The advanced interpolation bundle includes several advanced techniques that ensure robust interpolation and regularization of sparsely and irregularly sampled data, including data with large gaps. These techniques are multidimensional, i.e., 2D, 3D, 4D, and 5D, providing protection against aliasing by using domains where un-aliased low frequencies are used to interpolate to the higher aliased frequencies in the input data.

The use of 5D-interpolation techniques to increase the sampling of sparsely sampled full-azimuth land or ocean bottom cable/ocean bottom node (OBC/OBN) surveys, while still preserving the azimuthal variations in the subsurface is critical for subsequent detailed azimuthal AVO workflows. The algorithms included are matching-pursuit Fourier interpolation (MPFI) and time-domain Radon interpolation (TDRI).

Advanced imaging bundle

The advanced imaging bundle offers algorithms that can handle complex and rapidly changing velocity models, and image steep dips compared with conventional Kirchhoff approaches, providing superior images of the subsurface. This includes reverse time migration (CPU and/or GPU), finite-difference modeling (CPU and/or GPU), adaptive-beam (CPU only), and Gaussian packet migration (CPU only).

VISTA IVA

A comprehensive, interactive velocity-picking tool for 2D and 3D datasets, integrated into Omega software. It brings the user on-the-fly interactive velocity and analysis using semblance, offset stack gathers, constant-velocity stack (CVS), or multi-velocity function stack (MVFS). Other interactive features include cross-section and time-slice views of velocity data, and the interactive base map, where the user can modify parameters in real time. VISTA IVA also includes automatic and manual-picking options, 2D and 3D attribute views, eta semblance picking, AVO angle display, and muting options.
