MARVEL™

MARVEL is a complete, fully distributed seismic processing system. Each integrated module in MARVEL streams data through both local and broadband network channels. MARVEL automatically detects the available resources on each node and selects the optimum parallelization and efficiency strategies to maximize performance. MARVEL is a full 64-bit system and is available on a wide variety of platforms and operating systems, including Linux, Macintosh OS X, and SGI. It is optimized for speed and efficiency, and can run on Intel-based cluster systems and NVIDIA GPUs, and communicates over virtually all network implementations.

eyeBeam™—High Speed Beam Migration

The eyeBeam module in Merlin is an ultra fast solution to many imaging and velocity analysis problems. eyeBeam decomposes seismic data into effective beamlets and images those beamlets along rays generated by MARVEL's anisotropic raytracer. The eyeBeam module is

• isotropic, VTI, and TTI capable;
• capable of imaging from topography;
• parameterized using Thomsen notation: ε, δ, VNMO, ϕ, and θ;
• capable of producing full volume, and target line or crossline images;
• 20 to 50 times faster than Kirchhoff migration.

KDM—Anisotropic Kirchhoff Migration

Like its beam-based counterpart, the KDM module is fully paralleled over input and output so that large volume jobs are completed in a single run. It is also based on MARVEL’s anisotropic ray tracer so it incorporates many of the features that the raytracing module uses, including

• imaging with isotropic, VTI, and TTI models;
• imaging from topography;
• parameterized using Thomsen notation: ε, δ, VNMO, ϕ, and θ;
• full volume and target line or crossline output.

MERLIN®—Anisotropic Reverse Time Migration

• full waveform, isotropic, acoustic TTI, and full elastic imaging;
• user selection of an optimized finite-difference stencil;
• parameterized using either Thomsen (ε, δ, VNMO, ϕ, and θ) or stress tensor notation (σij);
• migration from topography;
• precise amplitudes.

MERLIN provides full waveform data synthesis and two-way migration. Merlin utilizes a user-selectable finite-difference stencil to compute variable density isotropic, acoustic TTI, or even full elastic synthetic seismic data. This module is the most accurate application in Marvel's arsenal since finite differences are the only approximations used in the implementation.

MERLIN provides the foundation for the most accurate illumination studies possible. Its full waveform capabilities assure high quality assessment of acquisition designs, and its efficiency ensures rapid turnaround. Merlin produces the most accurate amplitude volume used to extract horizon-based illumination maps you can find. Merlin is

• insensitive to strong velocity variations;
• less sensitive to velocity anomalies then Kirchhoff or other ray-based approaches;
• parameterized using either Thomsen notation (ε, δ, VNMO, ϕ, and θ) or stress tensor notation (σij);
• capable of migration from topography;
• ultra fast when run on NVIDIA GPUs.

MORK™—Anisotropic Phase Screen Module

MORK provides one way wavefield propagation for both migration and demigration using a dual-domain phase screen approach. It can be applied in the shot-profile, common-azimuth, or common offset domain as either a migration or as a de-migration. The methodology enables you to test various velocity alternatives and make significant velocity modeling changes prior to applying more computationally intensive methods. Key features include

• isotropic, VTI, and TTI migration and de-migration;
• parameterized using Thomsen notation: ε, δ, VNMO, ϕ, and θ;
• migration from topography in shot-profile mode;
• steep dip imaging;
• extreme wave equation migration speed—for example, 16 km cubes at 500 shots per hour.

3D SRME

The multiple bounce prediction and matched filter suppression approach used in MARVEL’s surface related multiple attenuator, SRME, is very robust. Unlike other implementations, Panorama Technologies' SRME predicts more than one multiple bounce and uses all of them to design optimal match filters for the multiple suppression stage. The SRME module includes adaptive data regularization for improved prediction capabilities, and is implemented in the frequency domain for superior speed. It includes three-dimensional data regularization and multiple bounce prediction and match filter suppression.

It is fast and can suppress multiples in 40 Blocks of Gulf of Mexico data in 48 hours using just 16 12-core nodes.

VIEW3D™

Earth models are derived from a combination of redundant seismic data, borehole data, and interpreter intuition. The View3D module can produce complex geologically consistent models in a straightforward manner. This module includes the technology to:

• visualize data in three dimensions, including interpreted horizons, and 2D lines as a function of CDP, line and offset;
• construct complex, geologically consistent Earth models from well log data and interpreted horizons;
• integrate borehole data into the seismic imaging process using either statistical or horizon-based projection.
