Vector High Fidelity (VHF) – High Frequency Enhancement and Noise Attenuation

VHF is a revolutionary new tool that has been proven effective in reducing drilling risk in virtually every petroleum province in the world. Based on important breakthroughs in seismic noise reduction and signal extraction, VHF has the unprecedented ability to simultaneously reduce noise and significantly enhance the natural bandwidth of virtually any seismic survey. By fully exploiting the dynamic range of modern seismic data and effectively and reliably removing more noise than any other product in the geophysical toolbox, VHF exposes stratigraphic detail previously buried in the seismic image. Many of Vector's clients are using post-stack 2D and 3D VHF on their existing seismic database to identify overlooked prospects and to help explain recent drilling history. In many cases, full reprocessing is not required to succeed in these objectives. If you have tried other high frequency algorithms and methods and come up short, it is time to try Vector High Fidelity (VHF).

Iterative Velocity Toolbox (IVT) – Beyond Interpolation

No matter how densely velocity control is picked on 2D and 3D seismic data, there is always the problem of error introduced by interpolation. A fundamental drawback of traditional velocity analysis and normal moveout correction has been the fact that crucial velocity information is constrained by the data at velocity control points only. IVT was designed to solve this problem by iteratively focusing the 2nd and higher-order residual normal moveout to produce a complete velocity field.

IVT produces optimally-corrected gathers and sample-by-sample, CDP-by-CDP RMS and interval velocity fields.

IVT can also determine eta, the 4th-order NMO coefficient, and extract and correct anisotropy effects.

Azimuthal Denoise (AZDN) – True Amplitude, True Azimuth 3D Noise Cancellation

Early in the 3D seismic revolution, Vector realized the need to attenuate organized source noise and at the same time recognized the difficulty of implementing noise-discriminating filters that would not only preserve amplitude but also be effective in non-uniformly-sampled domains such as azimuth. In response to this challenge, Vector has specifically engineered AZDN to attack seismic noise in azimuth domain.

A terrific new tool to complement and enhance the power of 3D stacking, AZDN also eliminates the need for summation, partial stacking, coherency, or other low-fidelity 3D pre-conditioning processes commonly-used to assist 3D auto-picking, processes which are known to compromise subtle velocity indicators of anisotropy and other important detail carried in the unsummed 3D traces.

For true amplitude, true azimuth, and full waveform integrity 3D pre-stack noise cancellation, AZDN is the clear choice.

Features

Pre-Stack Azimuthal Time Migration (PreSATM)

With the recent interest in azimuthal anisotropy and fracture detection from seismic data, Vector Seismic recognized that the only way to eliminate the inherent ambiguity between dip and azimuthal anisotropy was to develop a method of full pre-stack 3D time migration that did not compromise the valuable azimuthal attribute. This was a challenge that Vector, one of the industry leaders in processing seismic data in azimuth domain, could not ignore. The result is PreSATM, yet another innovative Vector proprietary algorithm, and a crucial piece of the puzzle for explorationists who require properly-imaged gathers in preparation for anisotropy analysis.

PreSATM is a sophisticated 3D pre-stack time migration algorithm that provides high-integrity subsurface imaging and razor-sharp focusing of fault surfaces without sacrificing azimuthal detail.

Now there is PreSATM—the right tool for full 3D pre-stack time migration in preparation for anisotropic analysis.

Features

3D Kirchhoff PSTM

A Superior Solution for Complex Imaging and AVO

This robust implementation of the Kirchhoff Method provides excellent solutions for imaging complex faults, intrusives and overthrusts.  The enhanced imaging and ability to produce preserved amplitude offset-dependent data for AVO plays a significant role in improving exploration success.

Radon DMO - 3D Dip Imaging for Full Azimuth and AVO

A method ideally suited for wide azimuth land 3D surveys. Production-proven, it has been used successfully on an estimated 500 land 3D surveys to date. Consistently outperforms EQ DMO, ProMAX 3D DMO, and many other 3D DMOs available for land 3D processing. Trace interpolation or superbinning schemes are not needed to obtain good results on sparsely populated surveys, bin fractionation studies or irregularly-sampled 3D surveys. Parallel computing has been implemented to provide maximum computing efficiency. Modest system resource requirements are needed relative to other DMOs. Published papers (available upon request) demonstrate advantages for preserved amplitude and high resolution processing. Radon DMO has the distinct advantage of outputting both, full precision gathers and "stack on the fly". Patented in the U.S.; patents pending in Canada and the U.K. 2D version also available.

Tracker - 2D/3D Residual Statics Software

3D autostatics based on Ronen-Claerbout. Fast results that consistently outperform the competition. Special features allow user to handle any kind of data problem including poor signal-to-noise, complex structure, and conflicting dips. It runs 5 to 10 times faster than most competitive programs, greatly reducing velocity statics iteration cycle-time. Extensive internal production use since 1989. 2D version also available.

Features

Silencer - 3D Prestack Noise and Demultiple

This was derived from Radon DMO research work. Successfully attenuates complex, long-period 3D multiples if there is adequate separation in apparent delta-t at far offsets between primaries and multiples. The algorithm also works effectively to suppress source noise (ground roll) and random noise. It is the perfect tool to improve signal-to-noise in 3D gathers for: AVO analysis, velocity analysis, attribute analysis, etc. Performs well on land surveys with poor or non-uniform trace-populations.

PSPI 3D One Pass Migration

Performs 3D migration on stacked data using phase-shift migration, plus interpolation. However, when PSPI is not needed, PSPC migration results can be obtained. This is a full V(xyz) migration that can handle complex temporal and/or spatial velocity variations. Parallel computing has been implemented to obtain maximum computing and yield fast results. A turning wave option for overturned geology is available in PSPI.

3D FK One-Pass Migration

A simple, fast, resource-efficient 3D migration. Quality of output often exceeds industry standards for F-K algorithms, and often is better than "high-end" migrations. The 2D version of this algorithm adapts well for 2D prestack time migration and has been used for 2D prestack migration at Vector for more than five years.
